Below is a list of common plants pests and easy ways to kill the little buggers. As an organic nursery, we use only organic insecticides on our plants. Since many of the herbs you grow are going to find their way to your dinner table, we recommend you use only organic insecticides too. These days, they are available at most garden centers. You will usually need to reapply all controls a couple of times to kill the young insects hatching from existing eggs and break their lifecycle.
Soaps can burn tender leaves.
Apply in the evening, in the shade, and rinse off about 15 minutes later. Oils also can burn leaves but must be left on the plants to suffocate the insect, so leave the plants in the shade for a couple of days after treatment. Don't apply soaps or oils on extremely hot days. These are small, round, winged insects that suck plant juices. They usually congregate on new plant growth, where they shed their wings and stay to dine.
