Zone 6a covers 28 days of last-frost dates. We measured Omaha, NE at Apr 14 and Flagstaff, AZ at May 12. Give us your town or ZIP and we'll use ten years of daily lows recorded at your own coordinates instead of the middle of that range.
Why these dates work in zone 6a
Zone 6a's last spring frost averages Apr 22 and first fall frost Nov 1 — about 193 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

Will pepper survive frost in zone 6a?
No — pepper is frost-sensitive. In zone 6a, wait until after the last frost (around Apr 22) to plant, and harvest before the first fall frost (around Nov 1).
