When to plant dill in zone 3a

In USDA zone 3a, sow dill around May 16, and harvest from Jun 25.

We don’t publish a planting calendar for zone 3a, because every date on one would be counted from a last-frost date this zone doesn’t reliably have. Dill takes about 40–55 days from sowing to first picking, and that part holds anywhere. For real dates, tell us where you are below and Garzed reads ten years of weather at your own coordinates.

Why these dates work in zone 3a

Zone 3a's last spring frost averages May 30 and first fall frost Sep 10 — about 103 frost-free days. Dill tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. There's also room for a fall succession sowing around Jul 23 for a second harvest before frost. One caveat: we haven't yet checked zone 3a against the weather archive, so those frost dates are an inherited estimate rather than a measurement. Give Garzed your location and it works from that location's own ten-year record instead.
