Why these dates work in zone 10a

Zone 10a's last spring frost averages Jan 31 and first fall frost Dec 15 — about 318 frost-free days. Celery 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 10 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Sep 1 for a second harvest before frost.
