Frequently Asked Questions
When do I plant pumpkins for Halloween?
For Halloween-ready pumpkins, plant 75–100 days before October 31 — late June to mid-July in most US climates. Smaller varieties like Sugar Pie need 90–100 days; large jack-o'-lantern types like Howden need 100–120 days. Plant too early and pumpkins ripen in August; plant too late and frost kills the vines.
How much space do pumpkins need?
Pumpkin vines need 6–10 feet per plant to spread. Standard varieties produce 2–4 pumpkins per vine and require at least 50 square feet per plant. Bush or semi-bush varieties like Small Sugar or Jack Be Little stay compact and fit in 25 square feet. Plant at the edge of the garden so vines can run into unused space.
Should I start pumpkin seeds indoors?
Only if your season is short (Zones 3–5) — start 3 weeks before last frost in large peat pots that go directly in the ground. In most climates, direct sowing works better. Pumpkins grow extremely fast once conditions are warm, and they dislike root disturbance at transplanting time.
How do I know a pumpkin is ripe?
A ripe pumpkin has fully colored orange (or mature color for the variety), a hard rind that resists fingernail puncture, and a dried, brown stem. The ground spot turns from white to yellow or orange. Leave 2–3 inches of stem when harvesting and cure in the sun for 10 days to toughen rinds for storage.
What should I plant with pumpkins?
The Three Sisters combo with corn and beans is classic — corn provides a trellis, beans fix nitrogen, and pumpkins shade out weeds with their large leaves. Nasturtiums and marigolds deter squash bugs and cucumber beetles. Avoid planting near summer squash or zucchini — they share all the same pest and disease pressure.
