Planting Guide and Seed Saving Notes for Dill

Dill (Anethum graveolens)

How to Grow Dill from Seed

Bed Preparation

Dill is an annual that prefers well-drained and slightly acidic soil. Choose a site with full sun. Provide moderate water.

Planting

Direct sow dill seed outdoors in spring after all danger of frost has passed. Optimal germination occurs when soil temps are 45-75°F. Sow seeds 1/8" deep and 4-6" apart. Seeds will sprout in 7-21 days. Thin seedlings so that mature plants are 8-12" apart.

For multiple harvests, plant seeds every 2-3 weeks. In areas with hot humid summers, dill may bolt, but can be replanted again when temps cool in the fall.

Harvest

Harvest leaves anytime during the growing season and seeds as they mature in summer.

How to Save Dill Seeds

Dill self-sows readily in the garden. Seeds mature in summer-fall. Collect seeds when flowers have dried and turned brown. Store seeds in a cool dry place. Seeds will remain viable for 3-5 years.
