Hydrangeas: When do I prune them? Why didn’t they flower?

Updated : June 17, 2024

Hydrangeas can be divided into two categories.  Those that bloom on the current year’s growth, and those that bloom on old wood, (last year’s growth).

The Hydrangeas that bloom on old wood are from the macrophylla family.  These include Nikko Blue, Endless Summer and many other pinks and blues.  When I say they bloom on old wood I mean that they are busy right now setting flower buds for next summer.   So next year when they take off growing in the spring, the flower shoots will actually emerge from the older wood, the wood that was produced this year.

The hydrangeas that bloom on new wood are typically the white hydrangeas like Annabelle and Paniculata Grandiflora (PG).  They put on new growth in the spring and then later in the summer the flower buds are actually produced right at the end of that new growth.  That’s why the Annabelle and PG are such prolific bloomers.  They set flower buds and almost immediately those buds produce big, beautiful, abundant flowers.  Almost nothing can go wrong with their blooming sequence.

But with the Blue and Pink Hydrangeas (macrophyllas) all kinds of things can go wrong with the flower buds.  Since the flower buds are produced in August and September they have to make it through the harsh winter before they can bloom.  The flower buds can be damaged by extreme cold.

Pruning?  You should prune macrophylla hydrangeas right after they bloom, before they have a chance to start making new flower buds.  Annabelle and PG hydrangea and other hydrangeas that flower on new wood can be pruned during the late fall, winter or early spring.  Once they start growing in the spring, do not do any pruning until after they bloom.

One of the most popular new varieties on the market is “Endless Summer Hydrangea” and it is known to bloom more than once in a season.  It’s in the macrophylla family and sets flower buds on old wood, but it is also known to set more buds and produce flowers during the growing season.  It should still be treated as a hydrangea that blooms on old wood.

So . . . with all of that said, if your hydrangea did not bloom then the flower buds might have gotten pruned off, or more likely the flower buds were damaged over the winter.

Hydrangeas like more water than most plants, and at least a smidgen of shade helps them stay healthy and happy.

    I pruned my macophyla too early and now this spring it doesn’t have any buds growing, some growth from the bottom. Will growth come back on the old sticks I pruned next year? Or should I cut everything to the base to allow the new growth to grow?

      Wait about two weeks and just remove the dead wood. Probably has nothing to do with when you pruned. They just do that sometimes.

    Does a Granny Smith Green Apple Tree need another apple planted near by to
    help Granny Smith bare apples. This is second year; other apple tree planted in same area died; so do I need to get another kind of apple tree to replace or can I
    just plan on one Granny to bare apples for a home garden.

    I have old, very established hydrangeas that, for the past four years, developed brown spots all over the leaves. It used to affect only half of the bushes but, this summer, all of them were affected. Many leaves turned yellow and fell off all summer. Since getting these spots, I have less than half the amount of flower clusters on the bushes than I had before the plants developed these spots. What is afflicting my hydrangeas and how can I repair the condition?

      It’s probably something that has to do with humidity and lack of air circulation. Prune them to allow air to circulate around the those branches.

    I live in Houston and have a 20 feet tall persimmon tree that blooms every year. However, it drops alot of its fruit when they get to the size of a large marble. Even so, there is still a large amount of fruit that gets to grow very nicely but the darn squirrels do a number on them and I don’t get to salvage but maybe 3 or 4 persimmons per year! I don’t know how to handle these critters. They are such cute creatures but oh so distructive! Anybody have a idea how I can handle this issue?

    I have had several Hydranges for several years in the same area that grow great but never a flower. I thought they were the pruning type so I did that but since never a bloom I left them alone and still no blooms. I see they grow new growth in the spring so then is when I trim out the old. What can I do to get them to bloom?

    My neighbors have very large hydrangeas, about 5 to 6 foot high. Mine die back every winter and form new shoots from the bottom. I have Niko Blue. It had two sets of flower buds on it, but a wild rabbit ate one of the. My concern is that even though I get flowers, the dieback in the winter keps them at only less than 2 foot high..

    This year, my potted hydrangea had several beautiful heads, just one plant, assorted colors, periwinkle, pink and lavender. The largest was 1/2 periwinkle 1/2 lavender. Thankfully I’d taken pictures! The next morning there was NOT ONE bloom on the plant! All gone. The stems seemed pretty straight, fairly flat as though cut but the patio is not visible outside our yard, we have 6ft privacy fence and locked gate. There were no ‘crumbs’ of petals or leaves Lying about as though eaten by a critter (and we live in an adult community…)

    How could this happen?There are squirrels, opossums, rats around but nothing I’ve read states they eat hydrangea blooms. And seriously? Every mophead, no leaves, nary a crumb or leaf dropped? What say ye?

          The local arboretum had a collection of fancy hybrid rhododendruns that got eaten every year at the bottom, up to the height of a deer’s reach. They put up an 8′ fence but had to increase it to 12 feet to keep the deer out.

          I read something in a book on fences a few years ago about an effective way to keep deer out. It is to put the fence sloping inward on an angle of about 40-45 or lower. They will not jump over the fence because they can’t tell for sure where the top is or what is on the other side. I moved last fall into a house with a 4 foot fence around the whole back yard. The deer don’t eat my hydrangeas but they feast on the hostas in the front yard. When I moved in it was November and the hostas along the front path looked sunburnt. One night the deer ate everyone of them down to the ground. In a week or so, they all came back up and many of them bloomed as if it was Spring although it was December. This year, they have been eating the hosta leaves for several weeks in several places in the front yard. They might come over the fence or through the open gate at the end of the driveway (it is hard for me to close so I leave it open most of the time) but they leave the hydrangeas alone. I trimmed out dead wood in them in the Spring down to the point where there were buds or new branches were growing and they all bloomed. The large light blue one was covered with large blossoms that I have not trimmed off yet. Some were also light purple or pink. The two smaller ones nearby had fewer and smaller flowers. They are all in full sun in the afternoon but the bigger plants did well this year.

            Update on my hydtrangea pruning. I cut off the dead old wood down to the highest pair of buds and they did well–all the big ones bloomed. I took a chance because I did not know what type they were when I moved here in November 2021. We had several days in the 60s and 70s this week but the buds started to swell before the warmer days so I’ll prune them the same way this year, just down to the highest (and often biggest) buds near the ends of the old branches. Knew they would not bloom on dead wood so left most of the old wood below those top buds. Did not know if the buds were new wood or leaves or flowers but they grew all of those and bloomed heavily. That large bush is next to my back deck and as high as the top of the deck railing; some of the branches and flowers come through the railing posts. I picked some of the flowers when they were fresh and put them in water in a vase. The water evaporated but the flowers dried blue and still look good. Some I picked in the Fall turned brown within a few days but were not in their prime when I cut them. Most of them still had small hints of color when I cut them but all turned brown soon after. There were too many to put in water so I tied some stems together and hung them up to dry. Will cut some more while they are still fresh and put them in vases to dry this year. I was worried that the afternoon sun was too much for them but it did not interfere with growth and blooming last year. A small one in the other end of the backyard in the shade did not bloom much but that might be because it is still too small. It had a few flowers and new growth of stems and leaves. It gets some midday sun but not the full afternoon sun the big blue one gets.

            How so I find out what my gardening zone is? My post office address is for an area that is about a mile south and east of here but I am closer to some other small communities. One large spread out one about 1-2 miles away is in zone 6 but our address is zone 7. Most olants I look at in catalogs give a range (3-9 or 4-9) so either 6 or 7 is in the middle and they should be hardy here. I lived in zone 6 for 32 years, only about 5 miles from here and a lot of the things growing in gardens at my new house are thriving, whatever the zone is. There are irises, daylilies, echinacea, shasta daisies, etc. and the daffodils are already blooming. March can be wintry here in SE PA or warm and it is unpredictable. 3 years ago, I had a fire in my old house and there was fresh snow on the ground on March 3 when we walked out of the house at 5 a.m. Yesterday it was 73 degrees, but that is unusual in mid-March.

    I have a blue hydrangea bush, with lush leaves, this year. It’s a few years old, and only bloomed once. I pruned it after the second season, because it hadn’t bloomed. It never bloomed again. It has sun most of the day, perhaps that is to much. What do I do now?
    I also bought several of the endless bloom variety, which also get a lot of sun. Is it advisable to move them, and when is the best time?

    Down south we have the kind in which the soil pH determines the color of the bloom
    It dies back to the ground during the winter but new stems evolve from the roots in the spring and blooms on new wood. It can be changed from blue to pink if one changes the soil pH.
    .
    I have imported the Ottawa, On kind which blooms beautiful white blooms profusely. The bushes are everywhere in that area of Ontario and always filled with white blooms. These spread from the roots and eventually a plant will become a mass..These are easy to divide, as I took rootings with stems, year before last, and about 6 bloomed last year in Ontario..
    My plant is now showing blooms on old wood and it is still in its container. This must be confusing. I garden in eastern Ontario and NW Georgia.

They have not fallen off the stems. Do I cut them off and if so where? Just under the bloom head? It has been about 3 weeks or so and I have been waiting for them to fall of and no go. They are slowly making a couple of new bloom heads on the plant. Just not sure what to do from here. Thanks Brenda

    my hydrangeas are prolific with healthy, compact leaves. the buses stems are not growing higher than the leaves. While they appear to be robust plants the flowers are scant to nil and the bloom is more flat on the underneath side, rather disc shaped and pink in color. They are ideally located on the sunny east side of the house and well watered and well drained and mulched. my question how do I get the plants to produce fewer leaves and larger and more blooms.

    • Mike says

      June 16, 2012 at 10:46 am

      Kate, if you are fertilizing your hydrangeas I’d stop fertilizing them. Fertilizer produces a lot of vegetative growth, but in order for plants to bloom they sometimes have to slow down growing so they have time to make flower buds. You can fertilize with something that is low in nitrogen and higher in phosporous. Phosphorous helps produce more flowers.

    Hi Mike, Love all the information on Hydrangeas. I have white ones out front but last winter I did not cut them back because they look nice for winter landscape and the birds love being able to get underneath and perhaps eat the dried flowers. Now I have this hugh ‘patch’ with lots of little flowers on them. Is that because I didn’t prune? It looks wonderful, however!

    My hyg. plant is beautiful, but 2 years ago I put it on the front porch and the wind here in Ok. like to have blown it to death so I brought it back into the house and for the last 2 years it hasn’t bloomed at all. For about a month now I have been giving it some miracle-Gro bloom booster every other week and I still have no blooms. What is wrong with it? Oh yes and I have pruned it back a little bit. Please give me some info about it. It is red when it bloomed.

    It is early Sept, and my hydrangeas have been ravaged by deer. Most of all the leaves have been eaten off. While I know I have to do something to keep the deer away, will these plants recover and hopefully bloom next summer?

    I have an Endless Summer hydrangea that we planted last early summer and had been doing well with new growth. Sadly, I came home from vacation yesterday only to find our yard mowed by the neighbor in a good gesture but completely mowed my hydrangea down. There is a small stem left, is there any chance it will recover or should I just replace it?

    Hi Mike
    I really appreciate all your advice. I have blueberry plants and I have a boron shortage, what fertilizer can I use for acid loving plants. Everytime I fertilize with 10-10-10 they look sick. Ammonium sulfate works but it doesn’t help the boron problem. Thanks

    Aloha Mike and your beautiful wife, I am so greatful to you and your wisdom in plants. However I do have them in my yard, but it is a small bunch. My landlord had them in here already and they are blue and a greenish pink color with a tinit of very light purple. They are beautiful to the eyes. However in different places here on the island on a higher elevartion where it’s temperature is much colder it grows beautiful and humungus. I mean huge and they are very happy there. Temp is about in their 50’s and it’s about 3000ft level high. Beautiful. There are times during the year when it’s pruned back and then later it’s gorgeous, just gorgeous. Well, I will always love those that I have in my back yard, I need to care for them and appreciate them. I live on the big island of hawaii a beautiful place. Well have a great week and god bless you and yours. Regards, Natalie a happy gardener….thanks to you.

    I work for a landscape company, and to be honest with you. Triming Hydrangias has always been by guess and by golly. Been lucky so far. Thanks for the information now I can skip luck. The bigest problem I have is keeping them alive. Plenty of water. Good drainage. Adequate shade. One hundred fifteen degrees. Watch them melt. Do you have any ideas how I can help them out with that. By the way. Live in Texas.

    Mike, I’m glad you reported on the Hydrangea. I have 3, I cut then back in late fall, 2 of these bloom each year although this year has been hard on them, so hot and dry. I water them at least once a week. I have one that is a pretty as can be with green leaves, but it has not bloomed since I planted it. So I guess it is a different kind, so I will not cut it back this year to see what it does next year. Thanks

    I have a beautiful white (Bridal) hydrangea that blooms every year — cut it back to about 6 inches in late fall or early spring. Like another person on here, I noticed brown colored spots on the stems. It doesn’t seem to have affected the plant as it has grown HUGE this year. It must be at least 36″ tall and is almost 5 feet wide!

    My question has to do with the color. Last year, when the bush flowered, the heads were a light green and then changed to white. Some changed back to a light green. This year when the buds flowered, they were a light green color and then only some of them turned white. Most of the flower heads remained a light green.

    I have done nothing different in my treatment of this hydrangea. Does anyone have a clue as to why this is happening?

    I am glad to hear about transplanting and how to propogate cuttings. I was going to ask about that, but I don’t have to. I do want to ask a clarifying question about transplanting though. Since my hydrangea is so huge and keeps spreading, how should I go about dividing it?

    Thanks,

    For the person that wanted to start a lot of African violets….many years ago, just on a whim, I put African violet leaves in each of the holes in a ‘frog’ {glass thingy for arranging flowers in a vase} and had the ‘frog’ in a low bowl in which I kept the water level about half way up the ‘frog’. The holes were just the right size to keep each leaf upright. Since I didn’t really care how many plants I got, wouldn’t you know that every single leaf developed a small plant! Being the ultimate procrastinator, the plantlets eventually died because I never transplanted them to tiny flower pots. Good luck! It sure beat my mom’s method of putting the leaf stem through a hole in wax paper and into a small glass. I guess you would use plastic wrap now.

    I know how to make the blossoms on my mopheads pink (lime) and I know how to make them blue (sulfur of some variety), but how do I make them dark purple? Several years ago, a neighbor gave me a cutting from her hydrangea that had the most beautiful royal purple blooms. I have made several plants from it (and from the offspring of that cutting) but lavender has been the best I could achieve from the flowers. I really want that dark, rich color that I took the cutting for originally, but it has totally eluded me. She said she put cottonseed meal on her plants, so I dutifully put cottonseed oil on mine, but no dark purple. Wahhhh! (stomping foot) I want PURPLE!

    What interesting reading, I have Endless Summer hydrangeas, about 10 of them. I understand they like to remain a bit stressed, therefore, I use Holly tone, just follow directions onthe bag, I use it again in the Fall, about half what is used in the Spring. I understand they grow on old and new wood, what could be any easier? Early in the Spring, I cut them back to about 18-20 inches and will have bushes about 3-31/2 foot tall. When in Italy a few years ago, I was told they put aluminum nails in the hole when planting, and there endless summer hydrangeas had unbelievable color, makes sense, that would be like using aluminum sulfate, which I have used, it is so good for getting (gradually) that pretty blue.
    I also have the Limelight Hydrangea that’s a beautiful plant also, it comes on (later August) just as the others are starting to look a bit tired.
    Love to hear comments. Linda

    We live in Northern California, and I have seen hydrangeas in Golden Gate Park, but they hate my garden. I planted several in a dappled shade with lots of water, but no go. Small plants that died over the Winter. There is an old estate called Filoli where the things are 8 feet tall and covered with blooms. Somebody knows more than I do about them!

    Hello all, I have found that hydrangea is probably one of the easiest and most reliable blooming shrubs in the landscape. Here in Eastern Tennessee (Smoky Mountains area), site all macrophylla and arborescens in an Eastern or Northern aspect (morning sun and afternoon shade), with moist, rich, well draining soils. I have found that they are pretty carefree in regards to maintenance. Add aluminum sulfate or soil sulfur for blue hues in macrophylla. Color can not be manipulated in arborescens so don’t waste your money adding chemicals to your soil.

    Arborescens can be “mowed” to the ground in late fall-early winter for size control and bloom (new wood bloomers). You can cut macrophyllas to the ground for re-shaping purposes, however, do not plan on any blooms the next season. In the more northern climes (zones 5 and lower), a layer of winter mulch would be recommended. The following season (2nd) they should flower nicely.

    I have found that it is always better to fertilize too little than too much. With good soil preparation at planting, your hydrangeas should not need any special fertilizing. Just some grooming from time to time. If you make your own compost (we gardeners all should be), include the hydrangeas in your compost broadcasting. Your hydrangeas will thank you for it!

Maybe you should buy a farm here in North Carolina, I’ll bet the growing season is long enough to grow them here, then you just have them harvested here and shipped to you. I’ll bet there are people here already that would have them in abundance and be willing to sell them to you. DRINK SQUIRT! g

    Mike, you of all people should know when you sow seeds that you don’t always control what happens and when… So goes the weddings and the dresses and female “growth patterns”. Good luck.

    Personally, I would rather deal with deadheading, and analyzing lack of blooms on my Hydrangeas. Thus my questions…Have had weak blooms this year on this little plant put in 6.5-7ph soil. Not blue but definitely not pink. Seattle is really cold this year. Neighbors have delightful blooms, think mine need viagra. Did you ever put out a hydrangea check list???

    Yeah, so the dahlias are wimpy too. One bulb didn’t even put out a shoot. Usually by August they are 4-6ft tall.

    I am in southern Indiana and the heat here has disrupted the normal cycle of plants. I have watered daily and yet the plants do not do well. Pumpkins did not set on, tomato plants look awful and tomatoes rotted on the vine, when they even set on. My strawberries had an early short production period. Blackberries also had a short early season. Young fruit trees did not set blossoms or the blossoms just dried up in the hot air. Few people planted any kind of flowers, trees, shrubs, etc. Hydrangas that did well last year looked like rejects this year, blooms small, dry, and not many on plant, leaves dried and curled. Temps reached as much as 105 with a heat index of 115. If winter is as bad as summer, we are in for trouble.

      My Hydrangeas bloomed blue in early June, but soon after began to dry up. They’re along the east side of our covered deck. Seems the only plants that did well this year are the Marigolds! Didn’t even plant them, they just came back in full glory!
      My Hydrangea trees look really sick, have lost all leaves up to near the tops. They’re now 2 years old and are around 20 feet tall!
      We’ve had 100+ temperatures with 115 to 120 heat index for almost two months. Finally has cooled into the mid 90’s now, but heat index still over 100. Humidity has been horrendous!

    A couple of years ago, I purchased two very sad looking hydrangeas from a nursery I buy many of my plants/trees from. These sad looking plants were 50% off since it was at the very end of the season and I wasn’t sure they would survive, but had not invested much money in them. We were having some landscape work done at the time and the landscaper tossed my newly purchased plants in the yard until he was finished with what he was doing, saving the planting of these hydrangeas til the very end. I knew then they would not make it since they had been lying in the yard, all dried up and in the heat of late summer for some time. Lo and behold, the following spring these two plants bloomed and bushed out to my delight. I have never pruned them at all and this spring, once again, they were the best looking flowering plants I had in my yard. One is in full sun and the other is in mostly sun with late afternoon shade.

    I planted 3 lilac trees and although they bloomed each year, the deer tore all the bark off the trees and they finally died a slow death. We had to have them dug up and had an oak tree put in the yard in their place but this time we put some protection around the trunk of the newly planted oak tree along with our other fairly young trees. The deer have no mercy on trees and plants and everyone needs to put something around each tree trunk to save them if you have a deer problem.

    I purchased a hydrangea from Home Depot several years ago around Easter time. I planted it in my flower bed shortly after I purchased it but it has never bloomed since. After about 4 blooming seasons I read up on the old growth, new growth info. I had never pruned it so at the end of the season 2 seasons ago, I cut it back, thinking it was needing new growth to bloom. It had several years to bloom from old growth so I assumed it needed new growth to bloom. However, it still has never gotten another bloom. I have no idea what type or variety it is. The bush itself is now huge and healthy. Do you have any suggestions what to do to get it to bloom?

However they are getting sparce, the plant is in the shade in a pot on the north sise of my house, I add new potting soil every year, and lift the crown, but the blooms and the leaves just look leggy. Besides pruning it back, what should I be doing for the plant so it will get a little bushier, and have bigger (and more) flowers?

    My hydrangas bloomed but hardly had any color. They weren’t really blue, pink or white–just a blah kind of beige…is there something I can supplement the soil with so I get prettier blooms next year?

      I had the same issues and tried a product called Hoffman Blue Magic aluminum sulfate. I put it in the soil in the spring every other week for about 2 months and my hydrangeas bloomed like never before. They were beautiful! I stopped doing that and the blooms turned that blah beige again so I started putting the product in the soil again and now the new blooms are a deep sky blue. The directions say to keep hydrangeas blue mix 2 tablespoons of product in 2 gallons of water and apply every 2 weeks.

      I was given a violet start and watered it once a week. It loves getting coffee pot rinse water and has been blooming quite a bit this year (it’s going on 2 yrs now). Don’t get the leaves wet when watering. Deadhead old blossoms when dried up.

      African Violets are so easy to start. My mother taught me how when I was a little girl. Take a leaf cutting as long as you can off one you want to start. Cover a small drinking glass – clear so you can see it – with aluminin foil and cut a small slit in it. Put the stem cutting into the slit so the water covers and inch or so of the stem (add more water if you see it is getting low). In about two or three weeks you should see roots coming out. Then it you leave it long enough – a month or more – a small plant will grow underwater. Simply take it out and root that into some African violet mix and cut the top cutting off. You can stick that in water again if it’s still long enough and do it over!

    Hi Mike, I have Hyg. that are supposed to bloom on the old wood. You can see the straight
    spikes with fat bugs in the late summer, but no matter what I do to protect them, the frozen snow and the deer ruin them and by spring all I have are cute little green leaves coming up that grow bigger and bigger with no flowers at all. I’m up 2,000 feet high – in Peru, MA. So the cold winter is no friend to my hygrangeas. All the other houses around have the type of hyg. that grow flowers at the end of the new wood stems. Loads of white puffy flowers….. for my neighbors but not for me. I think I’ll change my plants to the kind that flower on new wood!

    Thanks for the tip!

      Hydrangeas, like many other plants, need to go dormant and get some rest over winter. They can’t go dormant if they’re kept in a warm house all winter. It’s best to leave them outside in their natural environment. Give them some protection from the drying effects of cold winter winds.

      Hi Linda, I’m going to assume that you have an arborescens hydragrangea. Where you live the climate is very similar to mine here in mid-minnesota. It may have something to do with the weather this year, or, when was the last time that you fed them ? I recommend a bi weekly feeding with a water based plantfood like Miracle grow. Use a higher phosphorus content (the middle number of the total yield) it will make a difference. Don’t exceed the recommended dosage. Your practice of mowing them to the ground is a sound practice that many people utilize with excellent results, especially when they’ve gotten out of hand. Good luck, and, good gardening !

    I love Hydrangeas. Mine is beautiful this year – two different colors on the same bush. Amazing. It has been in the ground for 7-8 years. Not huge. Poor thing does not get much care, water, sunshine. I don’t know how it does so well. It MAY get pruned occasionally – if it is lucky. Maintains itself. I want to get a tree, but do they require a lot of care? I love them too. Did a wedding with fresh and dried several years. Beautiful. Wish I could give you some hints, but less may be better.

    I understand about the differences and how to change the colors etc. but my problem is more basic that that! I bought a blue hydrangea 8 years ago and planted it in my flower bed near the house. The following year it greened up beautifully but alas, no blooms! I left it in that bed for 3 years with the same results and then moved it to a large circular bed about 10′-15′ from the house. It has been there ever since and makes a beautiful 4 1/2′ tall bush but never blooms. It has very little if any dead wood that needs to be cut out. I have given it every kind of chemical recommended and even tried a lot of the “”old timers” tricks used 100 years ago but nothing worked. My grandmother used to put egg shells and coffee grounds on hers to make them blue! Some said to bury old iron nails around the bush but NOTHING has worked . It never has bloomed. Is it possible there are some bushes that are grown and sold that will never bloom again no matter what you do? I live in Maine but I do not believe this is winter damage as my son’s blooms every year and he is farther north in Maine than I am. Both of ours are planted in about the same type area as far as protection from winter elements. HELP??????

    I have three different kind of Hydrangeas: Lace cap, Forever Pink, Forever & Ever and Endless Summer. What I noticed this spring was the older canes didn’t look healthy and by that I mean they had an odd brown spotting up and down them. It took a long time for the leafing to begin (I wasn’t sure if they were even alive). Is there something wrong with my plants and if so is there anything I can do to help out my plants? Also, I did have a lot of the flower buds die off from the harsh winter. Do you prune these tips off?

Maybe the trees need some limbing up. They have always done well in dappled sunshine. Should I fertilize them with something. I live in the jersey pinelands. I was up in northwest connecticut recently and they are all over and just beautiful. Definetly thinking they need more sun.

    People have been asking, “How do I prune my hydrangeas?”

    The answer is simple. Just prune them to the shape you desire. Do not cut them all the way to the ground unless you want to completely reinvigorate the plant. But if you have blues and pinks, (macropyllas) that will cost you all of your blooms for next season. If you have PG or annabelle that probably won’t hurt a thing.

    But don’t do that kind of heavy pruning until after Thanksgiving.

    For general pruning, just prune them to the shape and size you desire. They’ll love you for it.

      Endless Summer help!

      Everyone in my zone 3-4 has had many problems with the Blue Hydrangeas blooming. They have lush leaves but no blooms. I have 4 bushes and had 2 blooms on them this year. Last year I had a few more blooms but two years ago I had many many blooms. This year I was the only person who had Hydrangeas for our two flower shows

      After asking someone on a forum at gardeners site he said they have to be fertilized many, many times to get them to bloom. Well, I only did the Aluminum Sulfate on them early spring and fertilized then and expected some blooms. I guess I should have used Miracle grow acid fertilizer every week as this person suggested. Up here I leave the old canes on my bushes and use them to trap the straw covering, in the Spring I cut back the old canes to new growth which is usually down to the crown of the plant… since we have hard cold winters up here. Right now they have lush leaves and no flowers! When we bought these they were said to bloom on old and NEW wood. !!

        It looks like I’m not the only one having trouble with hydrangeas. I have planted 17 this year throughout my landscape. Ughh! I had the biggest lavendar blooms, on the north side of my home and they lasted a few months and then they almost died as the summer took off and the thermometer climbed. I’ve fertilized with miracle grow and special fertilizer especially for these plants. It is as if the forces that be are not working with me. I have raspberry parfait hydrangeas on the west side and they have lost all leaves and look like they are dead to the bone. The white and pink hydrangeas planted as small about 4″ have all died to nothing. I had 9 blue hygrangeas planted on the north side of a building in the south lawn. Wouldn’t you know it they all died but one! I am so frustrated I could scream! I spent far more than I want people to know on my landscape just to have these plants up and croak or almost croak. I’ve given them plenty of water and fertilized carefully. Yikes!!!! I’m up for any and all advise I can get at this point.

          Judy,

          The basics of hydrangeas are pretty simple. Good rich soil that drains well, some sun but not full sun, adequeate amount of water and a minimal amount of fertilizer. When in doubt, use no fertilizer at all or just miracle grow mixed with water. Miracle grow is really safe, but with all other fertilizers you must be really careful. Plants that are under stress really should not be fertilized. It’s more important for them to establish themselves before they are fertilized. With the really young, small plants more shade would be helpful.

          Roses? Same advice except the shade, roses like more sun. But they do need to be treated for insects and disease. Bayer three in one rose and flower care has worked really well for me and it contains just enough fertilizer. It’s also systemic so it lasts longer.

      Mike, My mom received a white lace cap hydrangea 2 years ago I took it and planted it after its blooming cycle.It grew out nicely from its 8″ root ball size and 18″ high to about 26″ over the summer.No blooming of course.I pruned it back to about its usual height it was at 18″ at the end of august and it filled with buds all down the stalks. Last year…when the darn thing bloomed..it was the blue hydrangea ! I was sick about it. I can have all those darn things I want…the white lace cap was special..it was from my moms sisters funeral. It had 3 small blue blooms the size of an orange. The plant grew out nicely. Surely when I cut off 8″ it didnt affect its white blooming glory? I was wondering if the grower had grafted the thing to a blue hydrangea to get what HE wanted and it lost its DESIRE to bloom white.
      Any suggestions?

        Edward (Feb, 2011) Your problem is probably your soil. A few years ago I accused a nursery of mislabeling a hydrangea because the flowers were blue, not pink. What I learned is that hydrangeas react over time to how acidic the soil is…particularly the aluminum ions in the soil. I live in the NW and our soil is very acidic! The hydrangea simply adapts to its environment. If you are fertilizing yours, be sure you use very low or no phosphorus or sulfur.

        It is very difficult to change soil properties permanently and you can shock or harm your plants messing with PH, but you may add some wood ash and rich organic matter….but be careful; it is a slow and persistent process to change natural soil PH. I can’t guarantee this will push your bluish flowers back toward white, but it may. You might be better to enjoy the plant as it has adapted to your environment and cherish the memories associated with it.
