Why these dates work in zone 10b

Zone 10b's last spring frost averages Jan 15 and first fall frost Dec 31 — about 350 frost-free days. Beets tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. Starting seeds indoors 0 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Nov 5 for a second harvest before frost.
