When to plant winter squash in USDA Zone 7a

Plan your winter squash 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.

Asheville, Winston-Salem, Roanoke, Nashville, Little Rock. Average last spring frost April 15, first fall frost October 15 — a 183-day frost-free season.

Zone fit: good
Winter squash 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.
