Zone 7a covers 30 days of last-frost dates. We measured Fayetteville, AR at Mar 31 and Ogden, UT at Apr 30. Give us your town or ZIP and we'll use ten years of daily lows recorded at your own coordinates instead of the middle of that range.
Why these dates work in zone 7a
Zone 7a's last spring frost averages Apr 13 and first fall frost Nov 12 — about 213 frost-free days. Chives tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. Starting seeds indoors 8 weeks ahead gives strong transplants ready the moment the soil warms.
