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. Eggplant is frost-sensitive, so the 3w 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 eggplant take to grow in zone 8b?

Eggplant matures in about 70–90 days from transplanting. In zone 8b that means setting plants out around Apr 5 and first picking around Jun 14.

Will eggplant survive frost in zone 8b?

No — eggplant is frost-sensitive. In zone 8b, wait until after the last frost (around Mar 15) to plant, and harvest before the first fall frost (around Nov 15).
