How to grow dill

Dill is a tall annual herb in the carrot family, native to the Mediterranean region and Asia Minor. In a bed it becomes a vertical column of fine, blue-green, thread-like foliage on hollow, branching stems that typically reach two to three feet and need shelter from strong winds or physical staking to stay upright. Gardeners grow it primarily for its aromatic leaves and seeds, both central to pickling and to a broad range of savory cooking. It bridges the cool and warm parts of the growing season and must be direct-seeded into its permanent spot, because its long taproot makes transplanting consistently unreliable.

The hardest thing to manage is dill's rapid bolting in summer heat. A gardener who makes one spring sowing harvests well through cool weather, then watches the plant race to flower as temperatures rise. Once the yellow umbels open fully, foliage flavor drops and the tender-leaf window closes within days. The practical result is a bed of mature flower stalks at the exact moment fresh leaves were expected. Succession sowings every two to three weeks through midsummer are the only way to maintain a continuous foliage harvest.
