When to plant dill

Plant dill from the last spring frost to 2 weeks after it. Wait until the soil is at least 60°F. That works out to zone 5b (early May to mid May), zone 7a (mid April to late April) and zone 9a (early March to mid March).

Dill has a taproot and transplants poorly, so sow it where it will grow.

It reseeds freely.

Dill feeds swallowtail caterpillars, so plant extra.

When to harvest dill

Snip leaves any time after plants are 8 inches tall; harvest seed heads when they turn brown.
