Dill is an annual, self-seeding plant with feathery green leaves. It is used most commonly in soups, stews, and for pickling. Dill is easy to grow and attracts beneficial insects to your garden, such as wasps and other predatory insects. As soon as the plant has four to five leaves, you can start harvesting. Pinch off the leaves or cut them off with scissors. In your garden, plant dill next to cabbage or onions, but keep the dill away from carrots.
