How to Grow Pumpkins

Why Grow Pumpkins?

Pumpkins are versatile and rewarding to grow. From sweet pumpkin pies to savory soups, this crop can be used in countless recipes. Pumpkins also make beautiful fall decorations and are perfect for carving during Halloween!

Preparing the Soil

Pumpkins thrive in rich, sandy soil high in organic matter. Before planting, work compost into the soil to improve drainage and fertility. Additionally, add a balanced fertilizer to give your pumpkins a healthy start, as they are heavy feeders.

Planting Pumpkins

Follow these steps to plant your pumpkins:

  • Timing: Direct seed pumpkins after the last frost when the soil temperature reaches 60–65°F.
  • Spacing: Plant seeds in hills spaced 3–5 feet apart. If you’re growing giant pumpkins, allow 150 square feet per plant.
  • Thinning: When the seedlings have two true leaves, thin each hill to the two or three healthiest plants.

Watering and Mulching

Water pumpkins deeply but infrequently. Drip irrigation works best for consistent moisture. Use organic mulch to conserve water, but wait until the soil temperature is at least 75°F, as mulch can have a cooling effect.

Pollination and Seed Saving

Pumpkins require pollination to set fruit. If you want to save seeds, be mindful of cross-pollination between different pumpkin species:

  • Cucurbita pepo: Zucchini, acorn squash, and Howden pumpkins.
  • Cucurbita maxima: Giant pumpkins like Big Max and Cinderella.
  • Cucurbita moschata: Butternut squash and Musquee de Provence pumpkins.
  • Cucurbita argyrosperma: Cushaw pumpkins.

To ensure true-to-type seeds, hand-pollinate flowers early in the morning and bag the female flower to prevent other pollinators from entering. Learn more in our companion guide on growing gigantic pumpkins.

Dealing with Pests

Watch for squash bugs, which can damage your plants by sucking out their juices. Check the base of the stem and leaves for eggs, nymphs, and adults. You can also use traps, hand-pick the bugs, or place a piece of cardboard near the plants to catch them hiding.

Harvesting and Curing Pumpkins

Pumpkins are ripe when their rinds are hard, and they are fully colored. Harvest before the first frost, leaving a 3–4-inch handle on each pumpkin for better storage. Cure pumpkins in a sunny spot at 80–85°F for 10 days, ensuring they are kept dry. After curing, store pumpkins in a cool, dry place at about 50°F for extended shelf life.

Conclusion

Grow your own pumpkins for the best pies, decorations, and more. Grow organic for life!
