Beneficial Insects
Did you know that for every 1,700 insect species, only one of them is a pest? By focusing on spraying chemicals to target the one pest, all of the good insects and pollinators are harmed as well. If you instead focus on companion planting, you can trap pests and attract beneficial insects to target the pests.
For example, dill helps trap hornworms from tomato plants and basil helps deter aphids and whiteflies. To help you get an idea of what crops to plant together and to not plant together, I made a free companion planting guide here on my site.
