Why these dates work in zone 7b

Zone 7b's last spring frost averages Apr 5 and first fall frost Nov 1 — about 210 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 6 for a second harvest before frost.
