Dill has a long taproot and does best planted from seeds. Dill grown from transplant often bolts more quickly than dill grown from seed. If you plant transplants, choose young transplants and handle roots very carefully.
Plant dill seeds 1/8 inch to 1/4 inch deep. Thin seedlings to 4 inches apart. Keep soil moist until the seeds sprout.
Dill prefers rich, loose soil and full sun.
Broccoli, kale, kohlrabi, and Swiss chard are good companion plants for dill. Do not plant dill near carrots.
