Position and Soil
Give Pumpkin full sun (at least 6 hours a day). It does best in free-draining soil with a pH around 6 to 7. Dig through plenty of compost before planting, and mulch to hold moisture and keep weeds down. It needs an open garden bed rather than a pot, getting too big or deep-rooted for containers.
Sowing and Spacing
Sow seed about 3 cm deep. Thin or space plants to about 150 cm apart. Seedlings usually appear in around 8 days, fastest when the soil is between 20 and 32 degrees.
Needs real estate, a single vine can sprawl 4m. Plant on a compost heap and walk away. Harvest when the stem is dry and corky.
Care
Water consistently, roughly 15 L per plant every 3 days in warm weather, less in cool or wet spells. Feed every few weeks through the growing season with a balanced organic fertiliser, and keep mulch topped up.
Pests and Diseases
Keep an eye out for Powdery mildew, Squash bug and Pumpkin beetle. The main diseases to watch are Powdery mildew, Downy mildew and Fusarium wilt. Good spacing, watering at the base rather than over the leaves, and crop rotation prevent most problems. See our Pest and Disease Guide to identify and fix any issue.
Harvesting and Storage
Pumpkin is typically ready to harvest in around 120 days (about 4 months). Whole pumpkins in a cool dry place, up to 3 months. Cut pieces fridge for 1 week.
In the Kitchen
In the kitchen, pumpkin is good roasted with butter and maple, pureed into soups and pasta sauce, stuffed and baked whole and seeds roasted as a snack. Nutritionally: high in beta-carotene and vitamin A and rich in potassium and fibre.
Companion Planting
Pumpkin grows well alongside Corn, Beans, Nasturtium and Marigold. Keep it away from Potato. Our Companion Planting Guide has the full pairings.
