Why these dates work in zone 6a

Zone 6a's last spring frost averages Apr 30 and first fall frost Oct 10 — about 163 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 Jun 27 for a second harvest before frost.
