How to Grow Pumpkin — Croft & Covey

Growing Conditions

Pumpkins need warm soil (65°F minimum), full sun, and a long frost-free season. They are drought-tolerant once established but produce better with consistent moisture during fruit development. Vines spread widely — plan for 50–100 square feet per plant for standard varieties.

Cold climates: Direct sow after last frost or start indoors 3–4 weeks before for an earlier start. Choose varieties with 100 days or fewer for reliable harvest before first fall frost in Zone 5.

Warm climates: Direct sow after soil warms. Long seasons support large storage varieties.

Sowing & Planting

Sow 3–4 seeds per hill, 1 inch deep, thinning to 2 plants. Space hills 6–8 feet apart for standard vines; 4 feet for bush types. Or start transplants indoors 3 weeks before last frost in individual cells — handle roots carefully.

Care & Maintenance

Water deeply at the base — avoid wetting foliage to reduce disease. Feed at planting with compost; side-dress when vines begin to run. Once fruit sets, reduce watering slightly to encourage sugar concentration. Place a board or straw under developing fruit to prevent rot.

Common Problems

Squash vine borers are a serious pest in many regions — larvae tunnel into vine bases, causing sudden wilting. Row cover until flowering prevents egg-laying. Powdery mildew affects foliage late in the season — largely cosmetic at that stage. Cucumber beetles transmit bacterial wilt — use row cover. Poor fruit set from inadequate pollination — hand-pollinate if needed.

Harvest

Harvest when skin has hardened (fingernail doesn’t easily pierce it), the vine has died back, and the stem is dry and corky. Leave 3–4 inches of stem attached — pumpkins without stems rot quickly. Cure at 80°F–85°F for 10 days to harden skin further, then store at 50°F–55°F. Properly cured pumpkins keep 2–6 months depending on variety.

Varieties

Sugar Pie and New England Pie are small, sweet cooking pumpkins with dense flesh — far better for eating than large carving types. Jarrahdale is a blue-gray heirloom with excellent flavor and long storage. Cinderella (Rouge Vif d’Etampes) is a French heirloom with outstanding flavor and beautiful appearance. Large carving types (Jack O’Lantern, Howden) are bred for size and appearance, not flavor. For cooking and storage, choose pie or specialty varieties.
