About Dill

Dill self-seeds prolifically — plant it once and it will return year after year in most gardens.

Direct sow — dill does not transplant well. Let some plants go to seed for self-seeding next year. Harvest before flowering for best leaf flavour; harvest seeds once ripe. Good companion for tomatoes.
