What you need to know to Plant & Grow
Pumpkins are heat-loving crops that require full sun, rich soil nutrition, and a long growing season to achieve massive fruit size.
-
Direct Sowing (Recommended): Direct sow seeds outdoors from late May through early June once soil temperatures have warmed thoroughly. Plant seeds 2.5 cm deep in hills spaced 2.4 m apart, placing 4 to 6 seeds per hill. Thin to the 3 strongest plants per hill after emergence.
-
Indoor Starting: Start seeds indoors 3 weeks before outdoor planting. Sow directly into paper or fibre pots to prevent root disturbance during transplanting.
-
Giant Pumpkin Care: Work generous amounts of compost or well-rotted manure into the soil before planting. For competition-sized, maximum-weight pumpkins, prune vines to allow only 1 or 2 pumpkins per plant to mature, directing all plant energy into those fruits.
-
Harvesting & Storage: Harvest after approximately 120 days, before the first hard frost. Cut from the vine leaving a generous stem section attached. Be prepared to ask for extra help when hauling these heavy beauties in from the garden!
