Why these dates work in zone 7b

Zone 7b's last spring frost averages Apr 5 and first fall frost Nov 1 — about 210 frost-free days. Tomatillo 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 6 weeks ahead gives strong transplants ready the moment the soil warms.

Common questions

How long does tomatillo take to grow in zone 7b?

Will tomatillo survive frost in zone 7b?

No — tomatillo is frost-sensitive. In zone 7b, wait until after the last frost (around Apr 5) to plant, and harvest before the first fall frost (around Nov 1).
