Why these dates work in zone 9a
Zone 9a's last spring frost averages Feb 28 and first fall frost Nov 30 — about 275 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 Sep 7 for a second harvest before frost.
