Vegetable seeds used in organic production must be free of chemical treatments. If a crop is unavailable in non-treated form, authorization from certifiers is necessary before making purchase.
Choose varieties with the best insect and disease resistance and select early maturing cultivars. Late maturing vegetables are more prone to disease and insect problems. Earlier plants mature the less time insects and diseases have to compete for the vegetables. Vegetable rotations that have been used by organic growers in Northeastern United States are:
Sweet corn before potatoes, cabbage family before sweet corn, tomatoes before peas, beans before tomatoes, root crop after cucurbits and potatoes before root crops. Remember, vegetables from the same plant family usually have the same problems. Beans-potatoes, peas-carrots, cabbage-beets, peas-turnips, kohlrabi-beets, spinach-eggplant, corn-cucumbers, corn-beans, and spinach-cauliflowers are vegetables that do well when they are planted together.
There are some ways to repel insect in your garden; one is repellents, sage repels cabbage moths and black flea beetles but don’t count on sage working under pressure from these insects. But it might be worth awhile to plant a little sage with cauliflower, cabbage, and broccoli and chives have some repellant properties for aphids. And another is attractants, dill attracts the tomato hornworm, plant the dill on the opposite side of the garden from the tomatoes.
