    We seem to have an infestation of red spider mites in the greenhouse. I have been reading up on this. We are trying to stay as organic as possible. Who has an effective treatment?

    I had a major spider mite problem in my greenhouse last year and I tried ladybugs (didn’t work at all), spray of water on underside of leaves (didn’t seem to work much) and neem oil and didn’t have any luck. I cleared out my greenhouse and kept it empty for the summer. I’ve noted some signs of mites already and I’m cutting out suspect leaves, bursts of water and Take Down Garden spray. So far it seems to be working. I also planted brown mustard seeds all over my outside and inside gardens in hopes that it will help with the dreaded mites.

    Try mixing in a spray bottle a few squirts of Dr. Teals Tea Tree and Peppermint essential oil shampoo and a few squirts of isopropyl alcohol. This was the mixture we used at a plant company I worked for when we didn’t want to use pesticides.

      Come hell or high water I will prevail. If you want to give mustard seed a try I can send you four or five ounces (the seeds are tiny and I bought a ridiculous amount…I live in the suburbs not a farm). A couple of handful produce a ton of plants.

        Mustard repels them? If so I will plant lots!

    1 clove garlic, Crushed and smooshed or blender in 2 cups of water. whisk it up well. leave for 24hrs. Strain through a fine strainer. Dilute with 12 cups water. put it in a sprayer and spray plants.

    I had that problem with new trees and planted dill around them. It didn’t work immediately but the next season they were gone. On singular plants in a pot I had to use several methods first neem twice, second trim off badly infected leaves, third I sprayed all over with hot water, a few times. They are hard to get rid of.

    in the book square foot gardening answers by Mel Bartholomew page 119 he suggests

    buttermilk-spray (page 123)

    salt-spray (page 128)

    or garlic-spray (page 129) for predatory mites for heavy infestation


    1/2 cup of flour

    2-1/2 gallons of water

    and 1/2 cup of buttermilk

    you may need to apply 2 or 3 times


    1/2 cup of epsom-salt

    1 gallon of warm water

    also works on cabbage-worms


    chop up a large head of garlic and soak then with 1 tablespoon of cayenne-pepper in about 1 quart warm water strain and fill a spray bottle the water mixed with a few drops of organic dishwashing-liquid

    spray your plants liberally

    you’ll need to spray again every couple of days and for a week after all insects disappear

    thus spray repel slugs cutworms whiteflies aphids and many other insects

    i have not had to test these out myself thus good-luck and let us know what you find works best for you and your area

    Interesting. I wonder what the local seafood houses do with their shells!
