Also question is, how do I keep bugs off my plants?
A dish soap and water solution sprayed over your plants is the perfect way to keep aphids away. In a clean spray bottle mix 1 part dish soap to 10 parts water. Spray it over your plants, and the aphids will go find their lunches elsewhere. A small amount of dish soap will not harm your plants or anyone who eats them.
Moreover, does vinegar kill bugs on plants?
White vinegar blasts bugs on plants as an ingredient in a homemade soap spray. Mix a 3 cups water, 1 cup vinegar in a spray bottle and add 1 teaspoon of dish soap. Spray it on plants, including trees and shrubs, to get rid of pests. Direct the spray at the underside of the leaves to make contact with whitefly eggs.
Dawn liquid dish detergent in approximately a 2 percent concentration is a fairly safe alternative to commercial insecticidal soaps formulated to kill insects such as aphids, mites and scale on plants and keep them away.
