Growing Pumpkins in Jacksonville
Jacksonville sits in Zone 7b, with an average last frost of March 1 and first fall frost around November 22 — giving a 266-day frost-free growing season. Warm-season crops like pumpkin need soil at 60°F or above before transplanting; Jacksonville's frost calendar puts that window clearly in the late-spring to early-fall range.
Jacksonville's moderate climate supports pumpkin on the standard transplant calendar with minimal special accommodation. Succession planting — sowing fresh seeds or setting new transplants every 2–3 weeks through spring — stretches the harvest window and gives you a backup crop if pests hit the first planting.
Jacksonville's Zone 7b is classic transition territory for pumpkin. The season is long enough for a full warm-season crop without needing aggressive indoor starting — 6 weeks before last frost is enough for most varieties. Late frosts are the main risk; keep row cover available until 2 weeks after your average last frost.
Jacksonville's heavy clay soil benefits from raised beds or deep organic matter amendment before planting pumpkin. Clay retains moisture well but compacts easily — add 3 to 4 inches of compost and work it in to 12 inches before planting. Consistent watering (2 inches per week) is especially important in clay soil, which can crack and pull away from roots during dry spells; mulch around plants to stabilize moisture.
