Growing Potatoes in Bowling Green
Bowling Green sits in Zone 7a, with an average last frost of March 15 and first fall frost around November 15 — giving a 245-day frost-free growing season.

Bowling Green's moderate climate supports potato 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.
Bowling Green's clay-loam soils are productive but benefit from annual compost amendment — 2 to 3 inches worked in before planting improves drainage and nutrient availability for potato. Consistent watering (1.5 inches per week) paired with organic mulch maintains the even moisture that clay-loam holds well. Avoid working wet soil in spring, which causes severe compaction in clay-loam blends.
