Why these dates work in zone 8b

Zone 8b's last spring frost averages Mar 15 and first fall frost Nov 15 — about 245 frost-free days. Cabbage 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 6 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Aug 23 for a second harvest before frost.
