Why these dates work in zone 9b

Zone 9b's last spring frost averages Feb 15 and first fall frost Dec 10 — about 298 frost-free days. Pepper is frost-sensitive, so the 2w after frost timing builds in a safety margin against a late cold snap — setting plants out too early risks losing them to frost. Starting seeds indoors 8 weeks ahead gives strong transplants ready the moment the soil warms.

Common questions

How long does pepper take to grow in zone 9b?

Pepper matures in about 70–90 days from transplanting. In zone 9b that means setting plants out around Mar 1 and first picking around May 10.

Will pepper survive frost in zone 9b?

No — pepper is frost-sensitive. In zone 9b, wait until after the last frost (around Feb 15) to plant, and harvest before the first fall frost (around Dec 10).
