Dill seeds should be sown directly into the garden (dill puts down a taproot, so like carrots, it doesn’t transplant well) after the threat of frost has passed in the spring.
The soil temperature should be between 60 and 70ºF (15 and 21°C) for the best germination results. Seedlings should appear in 10 to 14 days.
Plant dill every couple of weeks until mid summer to ensure a constant supply into fall.
CHOOSING AND PREPARING A PLANTING SITE
Plant in full sun.
Choose a site that has well-draining soil that’s rich in organic matter. The pH of the soil should ideally be between slightly acidic and neutral.
Make sure to shelter dill from strong winds, as it can be blown over easily.
HOW TO PLANT DILL
Sow dill seeds about ¼-inch deep and 18 inches apart.
After 10 to 14 days, young dill plants should appear in the soil. Wait another 10 to 14 days, then thin the plants to about 12 to 18 inches apart (if they aren’t already spaced well enough).
