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. Zucchini is frost-sensitive, so the 1w 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.
