Why these dates work in zone 8b

Zone 8b's last spring frost averages Mar 15 and first fall frost Nov 15 — about 245 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.
