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. Lettuce tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. Starting seeds indoors 4 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Aug 1 for a second harvest before frost.
