  3. FYI for people with dogs, onion and garlic are poisonous for dogs. Dogs will get into everything you think they won’t. They won’t go near the Neem oil, because it stinks. That stuff smells like pine sol except worse. I have pretty good luck with Neem oil alone, but with slugs I use pesticides. In the bad heat they’re going right under your plants, which is where they were. I can’t salt the grass, I just seeded it last fall. And tobacco is hugely expensive compared to simple pesticides It hasn’t affected the birds, butterflies, or pollinators at all They’re all over the place, squash are getting pollinated in their starter pots already.
    However, I do pray over everything I use and place and intention in it asking that no beneficial insects are harmed. That is working. We manifest what we believe, hard as that is to understand. And technically this nursery moved into their natural area so it’s expected I suppose. Can’t blame them for trying, but they’re still gonna die.

  4. hi mike, we’ve had an ongoing problem with whiteflies on our tomato plants and some flat leafed evergreens, i can not recall what they are called at the moment. last year those evergreens were loaded with whiteflies. i expect it will be the same this year.

    my problem is not knowing if what i spray on them will affect the birds that go into them. they are the usual mundane variety flat leafed evergreen you can get in any nursery or place that sells plants. wish i could remember what they are called…:o) there are 3 or 4 of these evergreens planted in front of the west facing windows in our 3 season room. i don’t know how old they are as we just moved here 3 summers ago. but they are quite tall, at least 7 or 8 feet tall.
    we live in illinois, zone 5b.
    thanks mike, i really enjoy your articles.

  6. I wish you utilise cow urine also for spray as it saves a lot against red mite. My friend used to create his own insecticide in COPPER utensils. He used 4 containers and put about 1 lb of Tobacco,1 lb of chillies,one lb of
    Garlic and one Lb of Neem leaves in separate vessels and with the mouth covered he would allow the mixture to ferment for 15 days. He used to finally mix all andfilter after grinding each content in mixi. The same was used as a concentrate and the result were great. He was illiterate and could not explain the insects the solution eliminated. You may try it.
    He used sea salt a cheap solution against snails. He used to spread salt around his pols and were seen as snail free.

  7. What a wealth of information Mike. The garlic formula applied in a fine mist nearly anywhere it is dark and moist will also kill Mosquitos on contact leaving your yard nearly free of those pesky little critters! Garlic does not have an odor that last too long with our smeller! The formula lasts for just about 2 weeks.

  8. This was a very good article and you have to read it all to understand what you are doing wrong. A longtime gardener came to my house this week and saw the ring that went around several trees and asked if I had chemically killed all of the grass. He said “I he thought that after you sprayed with that type of chemical you couldn’t plant anything for l year. I said, I’ve just planted all of those plants after I sprayed and if you look closely you will see all kinds of new weeds coming up in the middle of the grass I killed. He had me thinking, was all of these plants I just put down going to die. Your article reaffirmed that I was correct. It kills whatever green you spray it on thru the leaves, not the soil. I used 4l% and new plants are already coming up where all of the brown is so I will have to take care of that.
    Thanks again Mike McGroaty

  12. I’d forgotten about the Epsom salt, and the tobacco grows wild around here- strong stuff! I so needed this, because I have been putting things off until perfect happened – Mirage! This also sounds like it would be a good soil cleaner for starting seedlings – Mike, Thank You!

  15. Thank you for these recipes!!! I have been fighting a losing battle against squash bugs, ants, and cabbage worms. Neem oil doesn’t seem to affect the squash bugs– but I think it killed my squash leaves. I have red about some of the ones you suggested, but noone ever said to use mild organic soap– I was using dish liquid in the mixes and I think my plants have suffered for it. Thank you for the advice of not putting the tobacco juice on my nightshades, for I certainly would have done it — I just bought some tobacco last week to make the elixer with it. LOVE the wealth of information I have gotten from reading your newsletters and learning from your backyard growing system this year. Thanks so much. Dulcie

    • .Stink bugs were destroying my opuntia cactus (prickly pear). I read on a forgotten web sift of how to get rid of them without using chemicals. What you will need is a shop vac ( an electrical cord to get to the plants) a nylon soc and duct tape. Cut the sock about 6 to 10 inches from the toe end. Stick the toe end first into the wand of the vacuum cleaner and fold the end over the wand about an inch or two and secure with duct tape. Now here comes the fun part: vacuum the stink bugs up. Do this a few times over several days until stink bugs are gone. Remove the sock, twist. The open end and dunk in water to kill bugs.
