I am a Community Gardner and we are 100% organic. We use a variety of insecticidal soap products, Safer is one I use myself. Works well, is organic and safe for edibles.
Example is at the link, but Lowe’s and other hardware stores sell it as well.
There is at least one insect you can purchase online that will help in your garden. The praying mantis will eat any bug that gets in it’s sight. They are the best insect in your garden and you can’t have too many of them. Try praying mantis/garden.com and you can purchase any amount you need. Also there is a repellent that i use in my garden that i mix up in the kitchen and will not harm your plants at all. Take a regular 32 oz sprayer that you can buy at the local garden market or any hardware. Mix 2 table spoons of lemon scented dish washing liquid with 3 table spoons of lemond juice in the 32 oz of water in your sprayer. Spray under the leaves and down the stalks and this will stop 90 percent of your insect problem. and will not harm your plants.
