Why these dates work in zone 8a

Zone 8a's last spring frost averages Mar 25 and first fall frost Nov 10 — about 230 frost-free days. Bok Choy 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 4 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Sep 15 for a second harvest before frost.
