Why these dates work in zone 7a

Zone 7a's last spring frost averages Apr 15 and first fall frost Oct 25 — about 193 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.

Will tomatillo survive frost in zone 7a?

No — tomatillo is frost-sensitive. In zone 7a, wait until after the last frost (around Apr 15) to plant, and harvest before the first fall frost (around Oct 25).
