Zone 8b covers 47 days of last-frost dates. We measured Fort Worth, TX at Feb 18 and Eugene, OR at Apr 6. 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 8b
Zone 8b's last spring frost averages Mar 6 and first fall frost Nov 22 — about 261 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.
