When to plant scorzonera in zone 3a

In USDA zone 3a, sow scorzonera around May 16, and harvest from Sep 13.

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. Scorzonera takes about 120–150 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. Scorzonera tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. 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.
