When to plant eggplant in USDA Zone 6b

Plan your eggplant planting around local frost risk and soil temperature, then work backward from the harvest week your buyers need. The calendar below is a starting point, not a field-level weather forecast.

Boone NC, northern VA, central KY, southern IN. Average last spring frost April 24, first fall frost October 8 — a 167-day frost-free season.

Zone fit: good

Eggplant is frost-tender, so timing the outdoor transplant to the last frost matters more here than in warmer zones. Row cover buys 2 weeks of head start.
