About pumpkins
Pumpkins combine autumn decoration, pie filling, and seed snacking in one sprawling vine that anchors fall harvest celebrations.
Spacing & yield
Pumpkins wants 48×72 inches and about 8 lb per plant at ~110 days to maturity.
Growing tips
- Direct sow or transplant after frost danger passes — count back 110 days from your desired harvest.
- Train vines in one direction to use space efficiently in smaller gardens.
- Limit each vine to 2-3 fruits for larger pumpkins by pinching off later female flowers.
- Slip a board or straw pad beneath developing fruit to prevent bottom rot.
Common mistakes
- Under-estimating space needs — each plant requires roughly 24 square feet minimum (48 by 72 inches).
- Starting too late and losing fruit to first frost before rinds harden.
- Overwatering mature fruit, which can cause splitting near harvest.
Harvest & storage
Cut stems 3-4 inches from the fruit when rinds are fully colored and hard, about 110 days from sowing.
Cure at 80-85 F for 10 days, then store at 50-55 F in a dry spot for 2-3 months.
Companion planting
Good neighbors for pumpkins: corn, beans, marigold, nasturtium. Avoid planting beside: potatoes, other cucurbits in close proximity.
Planting calendar
Start indoors about 3 weeks before last frost, then transplant 2 weeks after frost. Direct sow is also an option around 1 weeks after frost. Use the seed-starting calculator above with your real county frost date — the April 15 default is only a worked example (zone 6 style).
Estimates only — consult your local extension office for advice specific to your land and animals.
