Why these dates work in zone 6a

Zone 6a's last spring frost averages Apr 30 and first fall frost Oct 10 — about 163 frost-free days. Cantaloupe 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.
