Why these dates work in zone 3a
Zone 3a's last spring frost averages May 30 and first fall frost Sep 10 — about 103 frost-free days. Parsley tolerates light frost, so you can sow ahead of the last-frost date and keep harvesting into the cooler fall. Starting seeds indoors 8 weeks ahead gives strong transplants ready the moment the soil warms. There's also room for a fall succession sowing around Jul 2 for a second harvest before frost.
