Why these dates work in zone 7a
Zone 7a's last spring frost averages Apr 15 and first fall frost Oct 25 — about 193 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 Aug 30 for a second harvest before frost.
