Dill is an herb which can be grown for both its leaves and seeds. It is a self-seeding annual which will return year-after-year if seeds are allowed to mature in place.

When to plant: Direct from seed or transplants Mar–May (maybe June) or Sept–Oct

Harvest window

  • For leaves, harvest as soon as they are big enough to be useful.
  • For seeds, cut seed heads 2–3 weeks after blooming (before they turn tan). Place heads in a paper bag and hang in a dry location. Collect the seeds after they have dried and fallen off.

Care overview

  • Dill grows about 3' tall. Stake plants if needed
  • New leaf production stops when plants bloom. For a steady supply of fresh leaves, make successive plantings a few weeks apart..
