Why these dates work in zone 5a

Zone 5a's last spring frost averages May 10 and first fall frost Oct 1 — about 144 frost-free days. Pumpkin 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 3 weeks ahead gives strong transplants ready the moment the soil warms.
