Overview
Growing pumpkins beside the right neighbour
Pumpkin (Cucurbita pepo) is a vegetable in the Cucurbit family. Sprawling warm-season vine grown for large autumn fruit.
Pumpkins can stand in for squash in a three sisters bed — give the vines room to run.
Give plants 36–60 in in full sun. Aim for rich, well-draining soil with plenty of compost. In most gardens the crop sits in USDA zones 3-11 and is ready in about 90-120 days.
