Why these dates work in zone 9a

Zone 9a's last spring frost averages Feb 28 and first fall frost Nov 30 — about 275 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.
