Soil

Rich, well-draining soil with pH 6.0–6.8; amend generously with compost; pumpkins are heavy feeders requiring nutrient-rich medium

Frequently Asked Questions

Why aren't my Pumpkin flowers turning into fruit?

Pumpkins produce both male and female flowers that require pollination to set fruit — if pollinator activity is low, hand-pollinating with a small brush between male and female blooms can improve fruit set.

How much space do Pumpkins need?

A lot — they're vigorous vines requiring ample space and a long growing season of 75–100 frost-free days to develop their characteristic size and deep color, so plan for several feet of sprawling room per plant.
