Zone 7b covers 44 days of last-frost dates. We measured Oklahoma City, OK at Mar 12 and Reno, NV at Apr 25. 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 7b
Zone 7b's last spring frost averages Apr 4 and first fall frost Nov 12 — about 222 frost-free days. Sage tolerates light frost, so you can set plants out 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.
