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. Oregano tolerates light frost, so you can set plants out 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.
