Planting grass seed.
Planting grass seed is a pretty simple process, but there are a few things that you should know.
What Kind of Grass Seed Should I Buy?
There are People in Your Town that Would
Love to Buy Small Plants from You. Seriously!

First, let’s start with selecting a good grass seed for your situation and some mistakes to avoid. It’s best to buy a grass seed that is made up of a variety of different kinds of grass seeds all blended together.
Why a blend? Why not just 100% Kentucky Blue Grass?
There are several reasons for using a blend of grass seeds in your lawn. Like all living things, grass seeds can be attacked by different pests or conditions and if you have only one kind of grass seed in your lawn you could lose your entire lawn to an attack from insect, disease or other pests.
For instance, perennial rye grasses can be killed by pythium blight which is a disease that is triggered by really humid conditions.
This isn’t something to be overly concerned about if you have a blend of grasses in your lawn because the Kentucky blue grasses and the fescue grasses won’t be affected by the blight.
But you want perennial rye grasses in your lawn because they are quick germinating, they have a nice green color and most of the varieties used today have a fine texture, almost as fine as Kentucky blue grass.
Secondly, it takes Kentucky blue grass a long time to germinate, up to 28 days, whereas perennial rye grasses can germinate in as few as 5 or 6 days.
Quick germination is important because if you planted a lawn of 100% Kentucky blue grass chances are the lawn will be full of quick germinating weeds before the Kentucky blue has a chance to even come up.
So when you use a blend of grass seed, the fast germinating perennial rye grasses act as a nurse crop protecting the Kentucky blue grass seeds while they go through their long germination period.

The Price of Grass Seed Matters.
Like everything else, with grass seed you get what you pay for. My suggestion is to go to a place that sells bulk grass seed, maybe a full-service garden center or farm supply store and shop price.
Find a good middle of the road blend of grass seed. Don’t buy the lowest price and don’t buy the highest-priced seed.
If you buy really cheap grass seed it’s likely to have a lot of annual rye grass and other not so desirable grasses. You’ll end up with a lawn with a lot of thick bladed grasses that would be more suitable for a pasture.
A good blend of grass seed will have a blend of different kinds of fescues, different kinds of perennial rye grasses and some Kentucky blue grass.
Don’t get too worked up over the percentages because I don’t believe that the percentage of Kentucky blue grass in a pound of grass seed is accurate or relevant because Kentucky blue grass seeds are really, really tiny and have a lot more seeds per pound than do rye grasses.
I was once told that in a pound of perennial rye grass there are approximately 250,000 seeds whereas a pound of Kentucky blue grass will have close to 1.5 million seeds per pound! True or not? I don’t know. If you count them let me know what you find.
But in any case, use a blend of grass seed and opt for the middle to upper price range of seed. If you live in the south where grasses are warm-season grasses the same rules apply, it’s just that the kinds of grass you have differ.
Preparing the Ground Before Planting Grass Seed.
Before you start preparing the area you want to seed, give it a quick visual evaluation. Is it weedy? Does it contain thick bladed, undesirable grasses that you don’t want in your lawn?
If so, I highly recommend that you first spray the area with a non-selective herbicide that will not linger in the soil. I use something that contains glyphosate.
But keep in mind, non-selective means that the herbicide will kill any and all vegetation that it touches so read the label and wear the proper protective clothing.
Once you apply the herbicide you usually only have to wait about 72 hours then you can till under the weeds that you sprayed. They may not look dead yet, but they are.
If you prefer to not use an herbicide then just till the weedy areas. Wait about 5 days, till them again, and keep repeating this process. This constant turning then drying will kill the weed and any roots in the soil as well. I’d continue this process for at least two or three weeks.
You need to prepare the soil before you plant grass seed. If you just sprinkle the grass seed on hard-packed soil as soon as it rains or you water all of the seed will wash into puddles and you’ll have a lawn full of bare spots.
To prepare the soil you should work the soil to a depth of about 2″ to 3″ then rake the soil smooth, but leaving small clumps of soil won’t hurt a thing and will actually help to hold the seed in place.
By working the soil before planting you are giving the soil the ability to absorb water and not have it all run off. This allows the seed to get wet and become slightly embedded in the soil without it washing away.
If you work the soil too deep it will be difficult to get it raked out and it will later settle into a very uneven surface.
Planting the Grass Seed.
Once you have the soil prepared you want to spread the seed evenly over the area to be seeded.
A good rule of thumb for planting a blend of grass seed is 5 lbs. per one thousand square feet but I suggest you read the label on the bag or talk to your seed supplier just to make sure of what they recommend.
Just sprinkle the grass seed over the surface of the soil. If you use a rotary type of spreader you will get good even coverage.
You can buy a spreader with wheels that you push, or if you are doing a relatively small area they make small handheld spreaders that you crank. Either one works just fine.
Once you have all the seed applied what I do is take a push broom and drag the push broom over the surface of the area that I just seeded.
What this does is lightly mixes the seed and the soil and covers some of the seed with a light layer of soil.
This aids in germination and also hides the seeds from the birds. But don’t overdo it. Just drag the broom backward with a slight amount of down pressure.
Mulching Over Grass Seed.
Once you have applied the grass seed to your lawn you should apply some kind of mulch over the seeded area. There are a number of options.
Straw is the old standard and considered somewhat old fashioned, but straw has its advantages.
When you spread straw over your seeded area the straw lays in a criss-cross pattern and some of the staw is against the seed and the soil and some of the straw is slightly elevated over the seeded areas because it is crisscrossed.
Think about the size of grass seed and how tiny it is. With a single strand of straw suspended over a grass seed that single strand of straw actually provides a great deal of shade over the seeded area like lattice over a patio.
That’s one of the advantages of straw. The disadvantage? It blows all over the place.
What about peat moss?
I don’t like using peat moss over grass seed because peat moss is either wet or dry. When it’s dry it’s hard to get wet. It actually repels water.
Once it’s wet it stays wet and if you keep it wet it’s fine. But if it dries out it’s difficult to re wet it. Is peat moss terrible to use over grass seed? No, but it doesn’t provide the shade that straw does.
What about Grass Seed Starter Mulch?
You know, the green stuff in a bag that looks like hydro-mulch? I actually like this stuff because most it also contains just the right amount of starter fertilizer for grass seed and it’s easy to apply by hand or with a spreader.
When it gets wet it swells up and holds moisture pretty well. I’ve used it a number of times with really good results. I like it.
What about Hydro Seed?
Hyrdo seed shmyro seed! Hydroseed is okay but there is no magic in hydroseed. Hydroseed contains three things. Grass seed, whatever kind you select, hydro-mulch which is okay but nothing special, and fertilizer.
I’ve done a lot of hydroseeding and I can assure you, hydroseed works exactly as I described above. When you hydroseed you fill a big tank with water, then you dump in grass seed, hydro-mulch, and fertilizer.
Sometimes if you are seeding on a hill they dump in glue. Yes, glue. Does the glue work? I dunno. It holds for a while but when it does wash it takes large areas with it.
The big advantage of hydroseed is that the seed is thoroughly soaked before it is applied. So if you seed manually then water really well you’ve accomplished the same thing.
Hydroseed can and will wash out easier than a hand seeded lawn. And with hydroseed, everything is mixed together then applied as a slurry.
But this means that some of the grass is in touch with the soil and some of it is stuck to the hydro-mulch and is actually on top of the mulch instead of under it.
So . . . if you’ve got a lot of money and don’t want to do the work yourself let somebody hydroseed the area for you but don’t think that only a hydro seeded lawn will grow.
Grass seed is grass seed and the only difference between hydroseeding and hand seeding is the application process.
Take Care of Freshly Planted Lawn.
Freshly planted grass seed needs to be watered on a regular basis. You have to be really careful to not miss a watering because once you water the grass seed the first time germination is initiated.
If you miss a watering allow the seed to dry out once it has germinated the little tiny grass plant will die and the seed will be spent.
That’s why watering after you seed is so critical. Those little tiny grass plants are really, really fine, like baby hair. If you let them dry out they will die for sure.
That’s why I like seeding in the mid-fall or early spring. The soil temperature and air temperatures are warm enough for good germination but the sun is not as hot as it is during the summer months.
Spring and fall are the ideal time for planting grass seed. And it usually rains more in the fall and spring.
Okay, what did I miss?
Thank you, I have been trying to grow grass and I haven’t been successful.
Planting a new lawn, again. The last time I planted, the moles loved the soft earth. About 10 days after planting, I had a soft green covering of new grass, After about 10 days, the moles moved in and they had tunnels all over the yard, I gave up. Time to try again. Rototilling will begin within days but I need to know how to keep the moles out of the yard BEFORE this project begins. Thanks!
Joanne,
You have to get rid of their food source. See this; https://mikesbackyardnursery.com/2015/10/skunks-digging-moles-tunneling-why-are-they-digging-up-my-lawn/
You’ll never get rid of all the earthworms. Usually one mole can do all that damage! They are very territorial. When you first see them step on the tunnels instead of trap. I use a piece of conduit pounded into the ground and attach it to the trap with a hose clamp. Make sure the times are sharp! Works every time for me.
Over the winter I removed a huge rotting log, leveled out the area about 10×20 and about the 7th or 8th of April planted seed. It usually sprouts quickly and within 10 days it looks like success. Well it honestly looked like nothing was happening at all so 5 days ago I sprinkled a light covering on dirt over the seed. It was more like peet. Still nothing. I have never felt like a failure with grass growing so I reseeded. Two days later the grass is sprouting. However at least half of it is coming up red. I pulled one of the blades out and it is actually red. What could possibly cause this and will it turn green or did I kill it?
Marlene,
I wouldn’t be concerned but I would be careful to not over water. Here in Ohio it’s not usually to have an orange rust covering our grass when it’s hot and humid. As long as you had good seed I’d just be patient. Grass won’t grow well until temps are close to 70 degrees.
I’m doing an experiment and i need to grow grass fast. how can I grow my grass in a pot in winter? What steps do I need to take in order to fulfill a pot full of strong grass?
u guys are no help
u guys r no help
Davs,
Tell us more about the experiment. This article pretty much explains what you need to do. Indoors? You’ll need a light source. Maybe just a window. Grass should be up in about 6 days.
i followed what you said and i have 4 completely full pots of grass growing very healthily. thank you!
Mike,
I just found your article on seeding lawns. I moved to Rhode Island last year into new construction and like many people leaving comments, my contractor left me with a yard of shale and bread loaf sized rocks. I brought in nearly 50 cubic yards of loam this past year. I should have let it sit, kill the weeds then seed, but I didn’t and ended up with a yard of crabgrass. I killed most of the crabgrass and pulled up about 7-8 leaf bags worth of it.
My question is what should I do next spring to keep the crabgrass at bay and then what should I do to over seed the yard with hard, compacted soil? In the worst spots I have about 40-50% KBG coverage. I bought a John Deere spreader/spike aerator and have used it a few times, but I don’t think it does a great job. Thanks in advance for your advice.
Mark,
Your situation sounds challenging but not unusual. Cold weather will take care of the crabgrass. Normally you can apply a pre emergent in the spring for crabgrass but not if you intend to over seed. I’d forget the pre emergent, run the aerator over the lawn in the early spring, over seed, water as needed and really water as needed when it gets hot and dry. Crabgrass loves thin lawns that are easy to invade. Even if you get more crabgrass next summer just ignore it and and let the first frost in fall take care of it. My neighbor’s new lawn was a sea of crabgrass this summer, its’ now all gone and the grass is thriving.
We live in the western suburbs of Chicago and our backyard is on the east side of the house. We have what we believe to be a fairly large sugar maple in the backyard between the house and the fence. Growing grass between the tree and the house has thus far been an exercise in futlilty. This area is almost constant shade. What, if any, grass, can be grown in this area?
Barry,
Honestly? Probably none. Not just the shade but it’s extremely dry under that tree. I’d just mulch it and move on.
Hello,
We planted new seed this spring and it is coming up beautifully. Our only issue is that the ground is still soft when walking on it and mowing. We rolled it twice after adding the new soil. Will it harden up over time or is there anything we can do?
Jen,
Not really anything you can do, it will settle and hopefully still be level.
Great article! I have a bunch of leaf mulch. Would it be a good idea for me to cover my freshly seeded area with it? If so, how much of the area should be covered (i.e. how much of the grass seed should still be visible) and how deep a layer of mulch should I spread?
Nick,
You could and it would probably work fine but I’d make that layer as thin as possible, less than 1/4″ for sure. Landscaper recently did my neighbor’s lawn like that covering it with compost and it came up fine. Now it’s a weedy mess but I’m not sure why. All new lawns get weeds. Just get the grass established then deal with the weeds later.
I planted fescue mix a few weeks ago, i have a decent stand. I want to put more seed down to make it thicker but i don’t want to rake it in because i don’t want to disturb the grass that’s already growing. Will the seed grow by spreading it and watering it?
Nate,
It will, since there is already grass there that will act as a nurse crop.
I am in Connecticut, just had about 4,thousand square feet of new lawn installed. The landscaper covered the new lawn with Shredded straw. The next day we had a very heavy rain which caused a large area to wash out and the straw is now bunched up in a lot of places with bare topsoil showing.
I guessing a lost a lot of the seed but I don’t know.
Do I need to rake the shredded straw off the soil first and start over?
Can some of the straw be raked into new top soil in the washout area?
Do I need to reseed the entire area?
It appears the straw really floated around which I think means the seed has floated around or is completely gone.
Paul,
You’re probably right. Just move the straw around and put it back over the areas, then level the ground as needed. Reseed right over top of the straw and you should be fine.
I found it very interesting when you talked about tilling the weedy areas of your lawn before planting grass seed. My husband and I bought a fixer upper and the lawns are just weeds and almost no grass, so we want to at least turn the front lawns into grassy areas that we can walk on. Thank you for the advice about constantly turning the soil every few days for a few weeks before you plant the seed to dry and kill the weeds and any roots that might be lurking in the soil.
I had a moss problem in my yard. I killed off the moss and did my best to rake up the dead and still green spots of moss. I’ve self thatched and had it core aerated. I’ve just mowed and am ready to apply lime, overseeding and Milorganite. In what order should I apply each product or do I mix them all together and apply? Then since it’s already the beginning of June, how often should I set my sprinklers; like to come on beginning at 5am for 15 min and continue this schedule say again at 9am, 12noon, 3pm, and lastly at 6pm ?
Laurie,
The order doesn’t matter but don’t mix them. Your watering schedule should be fine. If too wet shorten the duration.
What do you do if you’ve planted sod and now its greening up ok but very lumpy? :/
Not much you can do but roll it if the ground is soft enough. Ground should be very smooth before sod is laid.
i have a 50 pound bag grass seed i`ve had for 5 years
is it any good has 3 or 4 kinds of grass seed
Ron,
That’s a long time and I honestly don’t know.
Hi Mike,
I always love your informative e-mails. You do a great job! Love your donkey buddies too.
I have bermuda grass (I think) that is invading my lawn. It is in several places and around this neighborhood. I have a location that I need to till up and put in grass see but it is loaded with that darned grass. It has extremely deep roots and I have tried roundup with no luck. It seems impossible to kill. Any suggestions on what I can do so I can have nice grass in that area so it matches the rest of my lawn.
Thank you so much,
Jan
Jan,
I believe the roundup will do the job but if there is nothing to replace it, seeds will grow. Spray, wait 72 hours, till and replant immediately.
I have a lot of weeds in my yard. and have compacted soil. My lawn is probably more than 50% weeds. In addition, the grass I have now seems to only grow to at the most 2 inches high. . I was going to use a weed and feed before planting, but wonder if it’s better to kill everything and start over? . If I do kill everything what is the best way to remove the vegetation? A sod cutter? Also, what is the best way to loosen the soil? Should I use my roto tiller or spread something on it? I live in central Ohio and only have about 6 weeks for the grass to establish before the first frost.
Carrie,
Only you can decide whether or not to kill the entire lawn. If you do, be sure to use something that does not linger in the soil like a glyphosate product. You do not need to remove the vegetation and do not roto till. Simply over seed, ideally with a rented over seeding machine that will loosen the soil slightly. The frost isn’t going to harm your new grass but you do need to get in done while still warm enough for the seed to germinate.
Mike
Can you please help.
we just did a large extension in south N.J. and the excavator brought in some “topsoil” to cover parts of the yard that was too sandy and rocky. Turns out the topsoil was from another site and had lots of large rocks glass and other garbage in it , though the dirt is much darker and moister than the sandy dirt before. So, what should be our game plan for planting grass seed. additionally he put in 4 dry wells.
Also, parts of the yard are always shady and parts sunny at times.
Thanks
Jeff,
I’m sure the soil is fine, just rake it out and plant the seed and use plenty of straw. This article contains a lot of information; http://mikesbackyardnursery.com/2014/02/lawn-installation-hand-seeding-hydro-seeding-or-sod-which-is-better/
Hi Mike,
We recently had a fairly large retaining wall, patio paver project.
A lot of new soil was brought in.
The soil was seeded, straw added and watered appropriately.
I think we just got in under the wire here in Wisconsin as I now have a green haze peeking through.
Possible conundrum…
The area is soft. I did not think to roll the soil.
Will the weight of our winter snow compact the earth enough to allow mowing in the Spring without fear of sinking in?
If not, do you have other suggestions? Would we roll it in the Spring even though grass is now growing?
Thanks for your help
Robin,
It should settle pretty well over the winter, then roll it in the spring. If you have to touch it up in the spring do so really early or just wait until fall again. I really like planting grass seed in the fall. It’s almost effortless compared to all other times of the year.
Hi,
Love your advice. Question. Live in upstate ny Syracuse area wher it can get cold. Took a 27 ft above ground pool out. big area. contractor filled it in with fresh top soil and seed, lime etc. He did this on sept 23rd, in upstate ny, a little leate but temps have been ok for sure. After only 1 week, I can see little tiny grass coming up. Will these die in a couple weeks if we get a frost which is possible. Also, My biggest question, he put a LOT of straw on it , I mean a lot, Seems like its blocking the sun, but grass is still coming through. Do I have to rake this straw up if the grass does become and inch or two high? It seems like it gets entangled in the straw and I would kill it all if I raked it up. Can I leave this straw down over the winter to protect from frost and weather? Don’t know what to do.
Thanks so much
Mark
Mark,
No reason for concern your grass will do just fine over the winter. Don’t worry about the straw it will settle down and the grass will completely consume it. I just planted grass seed at my place in Northern Ohio today, September 30th.
Hi mike, just found ur site, I live in the middle of lower mi .just built a house, there’s no way I de be able to water the whole new seeded area,, now what? Haven’t seeded yet, what’s the best time 4 my location for sucessjudy
Judy,
Best time would be mid to late September. The grass will come up a bit slower but it will come up and will not be killed off by the intense sun. Just keep the weeds at bay until then. Me? I’d spray them with roundup it won’t harm the seed that you plant later.
I just prepared my new lawn and spread the seed three days ago, but forgot to rake the seed into the soil. Should I rake it in now, or is it too late?
Derrick,
Just take a broom and drag it over the seed backwards, then apply a nice heavy layer of straw. Straw is really important this time of year.
Hi my neighbor sprayed weed killer on my grass 3 weeks ago and burnt my grass. I brought some miracle grow top soil and grass seeds and a rake I attempted to take out burnt grass apply seeds and top soil I just wanted to know will the seed grows and how long will it take before I see results. I live in Maryland and I just planted the seeds in late May. Thanks for your help.
Jeanean,
If your neighbor used something like roundup the seeds will grow just fine. Keep them watered and I’d mulch with straw this time of year.
Hi Mike – I live in NJ and have a backyard full of weeds, bare spots, a hole where a tree was just taken down and a mud plot where a sizable yard shed was removed. I have hired a landscaper to dig out the whole yard, level it and seed it. He was supposed to do this 3 weeks ago, but due to rain and other delays, it hasn’t happened yet. He’s supposed to do it this week, but the temperatures are suddenly spiking to the 80s and are forecasted to stay that way for at least 10 days (lows at night, high 50s/low 60s) with a smattering of thundershowers also forecasted. Figures – just my luck – the temps are going from consistent 55-65 to 85 in a matter of days. But I can’t stand the lawn as is, it’s awful and embarrassing, so something needs to be done – I can’t look at it like this all summer. However, I’m pretty spooked because every article I read warns about planting during the summer in the northeast. Many say it’s a recipe for disaster and money down the drain. Although, it’s unlikely these high temps are here to stay – I know we’ll get another spell of more typical late spring/early summer temps – that’s just how it works in this part of the country. Given how much I hate the yard as is, I’m super committed to doing whatever it takes to make this work. I have bought sprinklers and timers and work part-time, getting home by 2:30-3 every day so I can supervise a 2nd and 3rd watering if needed. Do I have a prayer of it at least working enough so that it looks better than it does now? I don’t expect a full, beautiful lush lawn, I expect that will come in the fall when we can aerate and overseed, but I do want it to come in enough that it looks better than it does now, the kids can play on it and that it’s strong enough to mow (I’m picturing babyhair-like grass all summer). Any advice – from you or any other knowledgable readers – would be greatly appreciated!
Julie,
Keep in mind, growing grass in the heat of the summer is challenging, but not impossible. Landscapers and contractors plant grass all summer long. I highly recommend a heavy layer of straw, you can google the amount per thousands square feet but I’d say no less than one bale per 1,000 square feet, maybe up to two. Keep it well watered and you’ll be fine. If at all possible water in the early morning, mid day and afternoon, but come evening allow it to dry before the sun goes down. High humidity at night are perfect conditions for pythium blight which can kill rye grasses. But don’t stress over that. If it happens it’s not the end of the world, the rest of the grasses in the mix will be fine.
Thanks, Mike. So should the schedule be something like 7am, 12pm and 4pm? And how much time do you suggest for each watering? I’m as worried about over-watering as I am about under-watering.
Julie, That schedule would be fine, then adjust as needed. If the soil is still wet, just skip a watering.
Can you spread more seed over the top of straw if the seed has just been put down?
Bob,
Absolutely. The seed will find it’s way to the soil and germinate.
Mike, we planted our grass seed but the staw was blown away while we were trying to get the first watering. Now half has no grass and half has likely too much. The seed hasn’t blown away. It is supposed to rain tonight and tomorrow morning. I do have straw still but the wind isn’t due to die down for a couple days at least.
Suggestions?
Lori,
You can buy green mulch pellets for new lawns, like hydro mulch, actually work pretty good. Just keep what you have watered.
Hi Mike
Can you advise for Central Florida? I don’t care of type of grass just green and one that Hardy strong and tuff! I have 2 large dogs that run jump and tackle at fast rate of speed in playing. This has killed my grass in spots. It’s now last week of August and hot as all. The ground dirt is nothing I’d ever call soil! I’m from Ohio and this dirt is more like a dusty sand. Surprised anything grows in this! I seeded by getting a bag of Scott’s tall fescue in the spring and I did nothing just threw it about by hand watered a few times the dogs kept running about I thought I’d get nothing. But to my surprise it grew! Only thing is I wish I had put more down still have bare spots here and there seems dogs pushed it in some areas where it is now super thick. Where it is real thick seems to be holding up thru their running about better too. And also this seems to have choked out the weeds of many too. Only in those places where the seeds all came to gather. My question to you is can I do this over seeding and I mean by lots of heavy over seeding now? To hopefully get a strong tuff lawn? Choke out weeds? By just simply getting bags and tossing it everywhere? And what type would you recommend? I can’t till this ground cuz these dogs would just have a hay day and track too much more dirt in the house…. I just want a tuff lawn don’t care otherwise…. Dirt brings more fleas and dogs make more mess so need green! Thanks for your time my friend…..
I would just spread seed over the entire area, but you’ll have to get a seed recommendation from a local full service garden center. Don’t trust advice from a big box store, it could be fine, it could be the worst advice ever.
Hi Mike. I have 2 out side dogs that are just ruining my back yard. It seems no matter what I do to try and fill in all these bare spots they have made nothing is working. Please help! I loved my new yard when we for our house and I miss my grass!
Thanks,
Miranda
Miranda,
Not a lot you can do but fence off those areas for a few months while you get the grass replaced.
Mike, Thanks for all your great info. I am a Japanese Maple Junkie and not sure what fertilizer to use. Some recommended by the nursery is very expensive. I have access to well composted chicken/mushroom compost. I put a 5 gal bucket in a 30 gal trash can and let it ferment for a week and use it on my veggies and flowers. I dilute it first. Will this compost tea be sufficient nutrient for my maples. Thanks again for all your help.
Vasile,
Cheap fertilizer is the worst thing for Japanese maples. The compost is a good thing, but in all honesty I never fertilize any of the plants in my landscape. Never have and they always look fantastic. So don’t think that you “have to” fertilize anything planted in the ground.
Hello Mike,
We have alarge section of our yard that is covered in wild violets. It looks pretty now, they are blooming, but we really would like it to be just grass. We have tried re-seeding, but the violets are persistent and now covers a 20×20 foot section of our front yard.
And then there are other areas of the lawn covered in moss. Over the years we consistently add lime, but probably not enough.
Oh, and the moles are all over the same lawn, making the entire yard soft (their tunneling is everywhere).
To top it off, our well is located in this same area, making it difficult to determine what is safe to apply.
Havebeen reading your site for years and really trust your advice., soany guidance will be appreciated.
Tom and Sharon P.
Woodbridge, CT
Sharon,
With the well and all I would recommend just tilling the area, let it dry, till it again, let it dry and repeat this process for a period of weeks. This should get rid of the violets. The moles are eating insects in the lawn, probably Japanese beetle grubs. You can try Milky Spore which is organic.
hi Mike i want to know what you use to keep insects from eating up your plants?
Patricia,
I rarely, if ever, spray any kind of an insecticide in my nursery. I don’t worry about a few bugs. The insecticide kills all of the bugs and some are important to the balance of nature.
Just finished counting the Kentucky blue..
1lb equals 1,468,902
Nice Rob. We appreciate you doing that for us.
Hello,
I am in need of some major lawn repair this year. A lot of the back lawn is dead/thinning due to high traffic area from kids running around on it. This has been an ongoing issue for quite some time and we have usually just fixed up the spots in the spring. We have moved the entire play area to our front yard but I’m afraid it was probably a little too late. Winter is now over here in Maine, spring is starting to arrive and the area to be redone is now a large area. What/how do you recommend we fix this? Should we till the entire area; have loam hauled in or not; what type or mixture of seed to buy; straw vs. mulch; etc.? Any tips would be much appreciated. Thank you!
Laurie,
I’d just get enough topsoil to fill any holes, spray any weeds or thick bladed grasses with a generic herbicide, seed and straw. You don’t have to till but you should scratch up the surface before you seed. Buy a good blend of seed, not the cheap stuff. Cheap grass seed produces a very cheap looking lawn.
Mike
I think you might have answered above about soil, but I am still a little confused. Although I probably shouldn’t. Long story short, we had to have a sewer line replaced and they brought a backhoe and dug up the lawn in front of my house from the house to the hedges ( street curb ), They put the dirt back into the long hole after it was done but there are so many stones. I bought a landscaper rake and wanted to rake away some of the rocks on top and then put soil down that I got at Home D- ( not sure if u want whole store names mentioned ) – then after reading some things you say here, it dawns on me that this dirt/soil that was “turned over” is the same that the remaining untouched grass was planted on originally. My big concern was I thought if I just put seed down on this hard dirt, would it penetrate or grow past the many smooth stones ? Or should I still put a layer of lawn soil down anyway ? Not sure what previous owners did, they are long since passed and I never discussed it. Am I over thinking ? If I just sprinkle seeds and keep moist I could have success without lawn soil ? My other fear is birds eating it, so perhaps a layer of lawn soil gently broomed over would be a good idea……I hope I make sense 🙂
Pete,
I understand your concerns but I have installed lawns in some of the rockiest soil imaginable. Put that store bought soil down right before you seed certainly isn’t going to hurt anything. Put the soil down, seed, then take a push broom and drag it backwards over the seed area. That will mix the seed with the soil. Then a fairly thick layer of straw would help to keep the birds out, but it shouldn’t be necessary this time of year. Just don’t miss any waterings once the grass starts to grow.
I planted winter ryegrass after having a new driveway installed to cover the dirt left by the construction . Can i just spread new kentucky blue grass seed or any other grass seed to establish my new lawn as the ryegrass dies off or must I till my yard under to seed my lawn with the new grass seed?
Tom,
As long as you are happy with the grading of the soil and don’t need to adjust that at all I’d just cut the winter rye close and over seed with a blend, not just Kentucky blue, but a blend that contains perennial ryes, fescue and Kentucky blue. It should come in fine if you seed it early in the spring.
I need plant grass in big patches around my yard. I just raked up the old straw from last fall. So its broken down and pretty fine stuff. Can I use that to cover my new seed???? and if i shouldn’t why ?
thank you.
getting ready to seed next week!
Kathy,
Absolutely you can use that old straw, it should be fine, good for the soil. Especially now when shade isn’t as critical. Fresh straw might provide more shade but maybe not.
I live on grass seed farm in Oregon and I can grow an entire lawn with just straw after the seed is harvested. It’s a bit uneven but it fills out just fine. What I’m saying is straw is a great start for mulch. If it’s wheat straw be prepared to pull a stalk or two.
My grass seed is doing great and sprouting everywhere. I planted just before my oak had finished shedding all its leaves so some have built up on top of my seedlings. How soon is it ok to rake them.up without disturbing my young grass?
Tonia,
Just about anytime, you really shouldn’t disturb the grass too much. It probably will do better with the leaves up rather than cover the new grass. Just rake gently to not uproot the grass.
Hi Mike, I just recently bought a house in Arkansas with a rock yard and want grass. The soil here is tricky and I was told that I had to bring in top soil. Is that correct or could I just remove the rock top they added and plant grass seed in the original soil that is rocky itself? And can i plant the seed now before winter comes. Thank you very much for your help.
April,
Years ago I installed hundreds of lawns. Back then we never brought in topsoil, we just worked the soil that was there. Sometimes it was sand and gravel, sometimes clay, others rocky as can be. In each case, with no topsoil, we got a beautiful lawn. Topsoil is loaded with weed seed or worse, maybe nut sedge. I’d just work what you have. You’ll never get rid of all the rocks, just rake it smooth and plant your grass. Yes, you can do it this fall. It might look sparse over the winter, but the roots will growing when the tops are not. Maybe over seed bare areas in the spring, you should be fine.
Mike…we certainly need your help. We have an area approximately 80′ x 40′ of previous grass that is enclosed by a 6′ fence in order to keep our German Shorthair Pointers within our property. In very little time, they, the dogs, destroyed the lawn. What was once grass covered became extremely muddy with every rainfall. We have since covered the area with straw, repeatedly, in order to curtail mud being brought into the house. Now we have approximately 4-5″ of compost under the current layer of straw. Here is our dilemma. We need to somehow restore that area of lawn before we even consider attempting to sell our home. As stated…we NEED help. Should we attempt to remove as much straw as possible before seeding? We have enough garden areas within which we could spread the straw. I don’t know that we will be able to roll the area anytime soon. The compost remains moist 24/7. Your advice, help and considerable knowledge greatly appreciated.
Jim
I should have mentioned that we live in the Dayton Ohio area.
Jim,
This is a bit tricky. If the composted straw is well composted it will perfect for growing grass seed. I think at this point I’d try raking up some just to be sure you have a seed bed for the grass seed. Rake up what you can and seed early this spring, probably right around April 1st in Dayton would be a good time. You might have to do a seconding seeding near the end of April. It really depends on the state of composition of that straw base. But I think you’ll be fine.
Mike,
We recently bought a house where the lawn is primarily weeds and moss. Some grass has survived but not much. There is also very little topsoil remaining and shows evidence of continued washing during rainstorms from the runoff due to poorly located gutters and the hill behind the house. We plan to install better drainage, reslope the yard, bring in topsoil where needed and start fresh. We know the soil is very acidic and we will need to apply lime as well as a non selective herbicide to deal with all the weeds in order to get a fresh start. In what order and timing would you recommend doing this? We will not be able to get the drainage addressed before we exit our prime grow time of September (we are in CT) and will be growing the grass in the spring. The yard currently receives a decent amount of shade though the front does get several hours of uninterrupted sun. We will be doing some more prunin/removal of overgrown trees so we will likely end up with more sun when we go to replant. I know fescues are the best for shade. Do you have any other recommendations for a blend? Given we do get some sun should we go with a perrenial rye and kentucky blue grass blend as well?
Thanks!
Lindsey
Lindsey,
For sure use a blend, if you have a significant amount of shade skip the Kentucky blue and get a blend of more than one perennial rye and at least one fescue if not two. You can apply the lime at any time, but spraying for the weeds can be done now, but more weeds will come. Best to spray 10 days or so from the time of seeding. Topsoil? I’m not a big fan of bringing in topsoil to install a lawn. I know that today that’s how all landscapers do it, but years ago we did not. We just seeded what was there, clay sand and gravel, didn’t matter we just worked it and seeded it. Topsoil has some nutrition, but not enough to sustain a lawn for very long. Lawns that are expected to stay really nice and green need to be fed anyway, so in my mind topsoil is just a waste of effort and money.
Thank you. The reason we have been discussing topsoil is given how much soil has washed away. For example cement footings which used to be level with the soil are now 4 or more inches exposed in many areas. There are signs of this all around the foundation and throughout the property. Would you suggest something else to bring the level back up to where it once was or just work with what is left?
Lindsey,
If you need soil to correct the grade, topsoil is fine. It’s just that all too often people are told that they “have” to bring in 20 or 30 yards of topsoil when in fact the soil they have is just fine.
Hi, a place down the road from me has a tow behind seeder for an atvthat drills the seed into the ground. Would this prevent me from having to add straw tho the area?
Matthew,
That will work just fine and if you wait until cooler weather it will work great without straw. What the straw does is protects the young grass plants, once the seed has germinated, from the intense summer summer. Here in northern, Ohio I would do what you mention with the drill seeder in late September and I would not use straw. That will give you the best results. You don’t want to waste the seed or your time so do as you suggest, just wait a few more weeks. Here in northern Ohio the 3rd week of September would be ideal.
HI Mike, I live in Michigan. We had hydroseed done 4 weeks ago. Luckily I work from home and kept the soil moist all throughout July and August thus far. The grass is spreading nicely, but since we have lots of elevated areas in our 1 acre lot, there are plenty of thin and bare areas. Granted, many areas will fill in on their own, but I purchased grass seed through a local bulk seed company anyway. We had some heavy storms that washed some of the seed away, so I figured it would be best to apply more seed in the Fall.
I plan on overseeding the entire 1 acre lawn this Fall just to give all the areas a nice kick start going into Fall and the following Spring. My question is about applying the seed. I should mention we’ve had a landscape company bring in 450 yards of topsoil as we are a new construction over clay soil. So things aren’t compact. Would it be best to apply the grass seed via spreader and use a roller to insure good seed to soil contact? Or will a couple of deep waterings (non puddle) help push the seed into the soil more. I was worried about using a roller over 6 week old grass.
Thanks!
Matt,
I’d use the roller. The weight of the roller is spread over the length of the roller, it should not harm your grass. Or use an over seeder that makes a slit in the soil, you can rent them. The over seeder gives the seeds a place to hide which makes washing away more difficult.
How do I get rid of large patches of moss in my lawn?
Jan,
Moss usually means that the soil is way too acid, apply some agricultural lime.
Hi Mike,
I live in Colorado and planted grass seed about a week ago after receiving lots of guidance from my local garden center. I have clay/rocky soil and they recommended bringing in a tri-mix of topsoil (with manure), which I did. I then planted the seed (about 350 sq. ft.). It has been stormy, cold, and rainy ever since. I am not sure how long to wait until I should start seeing seed or at what point I should think about replanting. I have a sinking suspicion the rain has ruined all of my hard work. Also, if I do need to replant can I just rake over the area and lay more seed? Thanks!
-Rachel
Rachel,
If the temps are above 60 you should see some grass plants in a week or so. You can lightly scratch up the area with a rake and re-seed, or just sprinkle more seed over top now and water it in and you should be fine.
Hello,
We just had our yard tilled and seeded two days ago. We’ve been watering it at night, but I noticed today the soil is dry by midday. I just reset our irrigation for morning, midday, and evening. After reading your article, I’m worried two days of dry soil may have killed the seed. Is it too late or will keeping it moist now be ok?
Thanks!
Katie
Katie,
You should be fine, your seed has not yet germinated. Once it germinates, that’s when the water really becomes critical.
Hello! I just planted grass seed in a large area. Tested soil, good. Tilled, good. I sprayed multiple times but some weeds were still very alive but there were so many they were hard to get rid of. To avoid hot summer temperatures we decided to couldn’t wait any longer and just need to plant the seed. We raked a little but I’m noticing the job was not well done and the ground isn’t that level and after many light rain storms water is pooling in small areas all around. Is that grass seed done for? Is there any way to level it better now (4 days later)? Thanks!
At this point there’s not a lot you can do without starting over. I wouldn’t be concerned about a little pooling water. For now keep it watered and hope for the best, unless you’re really unhappy with it, then start working the ground now before the grass comes in.
Thank you so much! You seem so knowledgable about all of this! So I shouldn’t get a roller to flatten more? I also used straw to cover seeds. I’m concerned it wasn’t that sterile. Should I try to try to remove it or just treat it all the weeds once the grass has grown in? Thanks again for your input. Much appreciated.
Most weeds are easy enough to control with some lawn weed and feed later. Almost all new lawns come up with some weeds present.
Hey Mike. I’ve recently ripped up my backyard and plan on spreading 20 yards of top soil combination 3-4 inches thick in some spots. Do you recommend tamping the area before seeding or should I seed and let it settle by itself? Thanks in advance.
Jamin,
The new soil should be reasonable compacted, then the top inch or so should be loosened to create a nice seed bed. If you don’t compact it, you will have all kinds of uneven settling.
I live in an extremely windy place and whenever i put straw over grass seeds it just blows away ,any suggestions on how to keep straw in place until seed germinates…
I think they make a jute netting for that. If you sow your seed early in the spring or in the fall, you don’t need straw, just use the green pelitized mulch they sell in bags. I like that stuff, whatever they call it, it works really well, holds lots of moisture. It doesn’t shade the seed, but it’s still easier than straw.
This weekend, i will be ripping up my entire front yard, leveling the ground, laying 7 yards of new topsoil mix. I have been looking the scotts bluegrass mix to use in east coast. I was told by a few landscapers to lay peatmoss over the newly spreaded seeds. I know you stated in your article to not really use it because of the water situation. Can you please provide any inside before i start this project on saturday.
George,
The peat moss is a terrible idea and extremely, extremely old school. Once peat dries out it’s nearly impossible to re-wet and it actually sheds water. The new green mulch with starter fertilizer works great. Make sure that blue grass mix has at least three or four other types of rye grasses and fescues in the blend.
Hi Mike! I have a Question, I want grass but my yard is big rocks and red clay. I am thinking bringing dumptruck of soil/fertilizer mixed and dumping, then spreading grass seeds and fertilizer, but my question is would I need to use bales of straw to cover or should I splurge and get the pre-rolled mats that has some seed built in to hold everything down? Just wanted your opinion. I will check back here to see if you reply, or you can email me
and put your name and growing grass in the subject. Thank you in advance & have a blessed day! 🙂
Gena,
I think you are about to create a mess. Grass tends to grow just fine in clay, it appreciates the moisture holding ability of clay. Just work the soil, rake out the rocks to get it level, then just seed and apply a grass seed starter fertilizer. Or better yet use the green granulated mulch with fertilizer in it. Do it now, not when it gets really hot. Bringing in soil is more than likely going to bring in a ton of weed seed of all kinds.
I live in Michigan, zone 5b and we built our house on top of a very high hill . Planted about an acre of grass seed (Pennington Ultimate). The ‘soil’ was hard clay and stone with some areas pure sandbox sand. The clay was like concrete and very difficult to rototill. We put down 1/2 to 1 inch at most top soil on the clay and a good 2 inches over the sand. Spread this Pennington Ultimate and applied a Scotts starter fertilizer. Watered every day with well water, high iron content, and now 3 seasons later it is so beautiful I and the Misses just like to sit on the porch and admire the beauty. A deep emerald green. I am no expert on growing anything but have learned so much from you. TY mike & tuey.
Thank you Mike for you kind words and congrats on a great job installing your new lawn.
I put dow weed and feed and covered that with straw was that a goid idea or did I mess up.
Mike, when you till the ground , should it be dry? The reason I ask is because the snow just melted away yesterday . We got out there today and did a little bit. I have no idea what I am doing! But it will get done.
Thank you!!
Jessica,
Soil is much easier to work with when it’s dry and you don’t really want to sow seed on cold soil. It takes warm soil for seed to germinate so you don’t have to be in a hurry. Get the soil worked and make sure it’s sill a bit loose when you sow the seed. Till it and rake it flat, then sow the seed. If the air temps are warm it will germinate in a matter of days.
I have been researching how to fix up my wreck of a backyard and everything gives so much unnecessary information. This was straight to the point and is wonderful! Thank you so much!
Kace,
Thank you, I appreciate that. I try hard to make gardening and landscaping as simple as possible. Be sure to check out my original site, http://freeplants.com for more great down to earth information.
Makes great reading. I have recently applied topsoil (taken off the park from mole holes) to my garden as the grass was not growing propperly. My friend advised me to add grass seed, so i did, then he said i should slightly turn it over, i did that too. Now i have lost contact with my friend who is on holiday, im unsure what to do now, maybe i should have flattened the soil first, as now it is looking abit off a mess out there. Can anyone advise me please ? Thank you

We just seeded and grew grass in a small area but the grass is sticky, any reason for that?
Trish,
Not sure what you mean by sticky, but I don’t think I’d be concerned as long as it’s growing.
I have this same problem. Very fine and thick grass. Sticky feel to it. After a few weeks of being one of the best looking areas in the neighborhood it completely turned to hay. It has been hot however watering has been done consistently. Haven’t mowed yet after a month because I’m afraid where the wheels run, the grass will not stand back up and smother itself.
John,
I’d mow the grass, I’m sure the lawn mower won’t hurt it. Come fall you can spot treat areas that have undesirable grasses. http://mikesbackyardnursery.com/2010/09/quick-easy-technique-to-fix-areas-in-your-grass/
I really hate it when an article metions peat moss to cover new grass seed! Like really hate it! I am the garden pro at my Home Depot. I have been doing this a very long time.
There are 2 distinct reasons we don’t cover new seed with peat moss. The first was mentioned here. Peat moss is one of the best natural water repellants there is. If you take a small mound of peat moss and put it on your lawn and hit it for 2 full minutes with your hose nozzel on the rain setting, and then push aside the top half, what;s left below will be bone dry! In the old days (long before my 59 years) farmers would take a pre-measured amount of peat moss and water and make a slurry by letting it sit until the water is absorbed, and then placing it on acid loving plants like blue berries.
The second reason we don’t use peat moss is the acid I just mentioned. Peat moss is highly acidic. Here in the northeast and at the end of our winter, our lawns have a PH (potential hydrogen) of between 5.2 and 5.8. Because the PH scale is between 0 and 14 with 0 being very acidic and 14 being very alkaline, we are trying to raise that PH to anywhere between 6.4 and 7.0 (7 is neutral on the PH scale). Because the PH scale is a logarithm, every whole number is 10 time the number before or after it. That means that every time we go up or down one whole number it will be 10 times the previous number. That is a huge jump! OK….so we are trying to get the PH of our lawn soils up after the winter. This is why we add lime. So we want to raise the PH by adding lime. Not for nothing folks, but peat moss has a PH of around 4. Looking at the PH scale you will see that is extremely acidic! You all see the so called “landscapers” use peat moss telling you…”hey Mr. homeowner! I just did you a big davor by covering your new seed with peat moss so you won’t have to water do much! What he just did was add an acidic product that reverses the action of the lime you just paid good money for. What does lime do? Lime does nothing for the grass plants…per sey, but it makes the nutrients in fertilizers “available” to the grass plants. In our soils is a substance called Colloids. Colloids are what holds Jello together and are also present in milk fats, which is why spilled milk becomes jell like. These colloids trap the nitrogen, phosphorus and potassium in fertilizers and keep them from the grass plants. Lime breaks the colloidial bond and releases those nutrients. Now just for the sake of mentioning it, when you purchase your spring lime, and unless you have a huge piece of property, do not use granular lime. This lime is pulverised dolomitic limestone and is actually incredibly tiny pieces of whole lime rocks. This lime works by water errosion and can take up to 2 years to travel 4 inches into your soil! I always suggest pelletized lime which resembles freeze dried coffee and reacts the same way to water. It disolves right away and begins working within a day or two, raising the PH quickly. Granular limestone is beneficial to golf courses and large pieces of propertry but the lime they put down now may well not work until next year or the year after. Go with the pelletized on your average 1000 sq ft lawn. By the way…the rule of thumb for lime is 40 lbs per 1000 sq ft of lawn. The actual formula is measure your lawns length by width. Multiply that number by 44 giving you the perfect amount of lime for any given area.
If you want to cover your grass seed with the correct product, my store carries a very good top soil for $1.98 for a 40 pound bag. Seed only needs to be covered by a small amount of top soil, keeping it moist and keeping it from “seeing” the sun so the seed doesen’t germinate popping the hull of that seed and drying out and dying. New seed should be watered twice a day for 20 minutes per areas at 6am and again at around 4 pm. This will keep the soil from drying out.
I agree with the mixture of seeds but I do not recomend Rye grasses. These are “feed” grasses and ar known as bunch or clump grasses. Bunch grasses grow out from a central point in the soil and growing up in the shape of an upside down umbrella. The only problem with thiese grass plants is that they leave open areas of soil below inviting weed seeds. I have and recomend Kentucky Blue Grass…especially if you have an underground sprinkler system and are good with the several feedings it requires over the course of the season. KBG is dense and won’t allow weed seeds a place to plant themselves.
I hope this helps! I have an e-mail address where I have over 3500 of my customers on my list. Every week I send out e-mails telling my customers what they should be doing at any given moment according to weather, temperature and time of season. They can also ask questions and send photos of their lawns and gardens. I do this on my own time. I love giving my customers great lawns and gardens…..that is the reward for both of us!
