Zone 7a covers 30 days of last-frost dates. We measured Fayetteville, AR at Mar 31 and Ogden, UT at Apr 30. 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 7a
Zone 7a's last spring frost averages Apr 13 and first fall frost Nov 12 — about 213 frost-free days. Pole Beans 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.
