When to Plant Pumpkins in Maryland

From jack-o-lanterns to pies, pumpkins need space and time but deliver a uniquely satisfying harvest.

The Short Answer

In Maryland, pumpkins planting dates vary by region. In Western Maryland, your average last frost is around May 1 - May 15, while Eastern Shore sees its last frost around Apr 1 - Apr 15. Since pumpkins are frost-sensitive, start seeds indoors 3 weeks before your last frost, then transplant outside 2 weeks after frost danger has passed. Clay soils in Piedmont. Sandy loam on Eastern Shore. Acidic in most areas. Rich alluvial soils along river valleys.

Growing Pumpkins in Maryland

Pumpkins in Maryland's Climate

Your season comfortably supports both short and long-season pumpkin varieties. Direct sow in late May to early June for October harvest. Give vining types plenty of space — 5-6 feet between hills. Powdery mildew is nearly guaranteed in humid summers — choose resistant varieties. After harvesting, cure pumpkins in sun for several days to harden the skin for storage.

Soil Considerations for Maryland

Clay soils in Piedmont. Sandy loam on Eastern Shore. Acidic in most areas. Rich alluvial soils along river valleys. Make sure soil has warmed to at least 65°F before planting pumpkins outside.

Maryland Climate & Growing Season

Moderate climate with four seasons. Hot, humid summers. Good growing season. Diverse growing conditions across the state. Pumpkins cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.

Growing season length varies across Maryland: Western Maryland (5b, 6a) has a last frost around May 1 - May 15, while Eastern Shore (7a, 7b, 8a) sees frost end around Apr 1 - Apr 15. This difference matters for pumpkins — transplant timing shifts by several weeks across the state.

Growing Tips

Count backwards from when you want ripe pumpkins (usually October). They need 90-120 days, so mid-June to early July is often ideal.
