How to Grow Pumpkins: A Delightful Fall Harvest

Want to learn how to grow pumpkins? The secret is to begin planting sooner than you might think!

These fall staples are easy, inexpensive, and generally low on maintenance, thriving in almost all climates.

Native to North America, pumpkin (Cucurbita spp.) comes in various shades and sizes, including red, pink, white, blue, and the popular sizeable spherical orange, ribbed rind fruit type.

All pumpkins are edible, but the ornamentals are best for carving.

Like most squash, pumpkins are low-growing vining annuals with large coarse leaves, blooming in July and August with orange-to-yellow funnel-shaped flowers.

They’re warm-weather lovers, requiring quite an extended period of frost-free weather to mature.

The seeds usually germinate within ten days in warm soil temperatures of at least 600F. Therefore, plant as soon as the soil is warm enough in the spring.

Start the seeds indoors—two to four weeks before your area’s last spring frost—especially in areas without the essential long growing season.

There is a little more to just the temperature requirements, but before we explore it all, here are the answers to some of the commonly asked questions about how to grow pumpkins.

Once you decide on the pumpkin variety and the planting time, go ahead and prepare the growing site.

  • Pie pumpkins are best for roasting and making pies. You want to try varieties like the Winter Luxury, New England Pie, or Baby Pam.
  • Miniature Pumpkins—great for decorative purposes. Try Jack-Be-Littles; they’re tiny with a relaxing orange tone.
  • Jack-O’Lantern pumpkins—They are less flavorful and larger than pies; they are best for carving. Try Rock Star, Howden, or Connecticut Field.

Preparing the pumpkin bed, planting, and care

  • Pick a spot that receives full sun most of the day. The location should be open enough (preferably twenty to thirty feet) for the far-reaching pumpkin vines to spread freely.
  • Till the soil tp four inches deep and work in organic compost to give the plants a boost of nutrients and also help improve the soil drainage.

Pumpkins love rich, moist, well-draining soil with pH levels of 6.0-6.8. Consider a soil test and amend with lime, compost, or bone meal.

  • Build a small mound(s), depending on the number of pumpkin plants you would like to grow.

Building mounds for starting pumpkin seeds

Mounds help warm up the soil, reduce pests, and improve drainage.

  • In the mound center, sow three pumpkin seeds (approximately 3 inches deep), then pat the soil over the seeds. Water thoroughly after planting.
  • Ensure a spacing of at least 1.2-2.4 meters if growing two or more pumpkin plants. 0.9 m (3 feet) is okay for the mini varieties.

You may want to consider sowing in a trench to help enhance the plants’ establishment process, primarily if you reside in an area with strong winds.

  • For transplants, space five feet apart; for easier sprawling and optimum yield.
  • Note that adequate spacing helps optimize the fruit size and not the number of fruits produced per plant.

Watering pumpkin plants

Water regularly, preferably in the morning, to keep the soil moist (not soggy).

Reduce your watering frequency once the pumpkins begin to turn orange, and then cut the watering entirely about a week before the estimated maturity time.

  • Right after the seedlings sprout, fertilize by spreading compost around their (seedlings’) base areas—to help encourage healthy growth.
  • Thin as needed, leaving the most robust plants.
  • Clip off the vines’ tips once they’re about five feet, so more side shoots can grow, which helps boost pumpkin production.

Pumpkins, in most cases, are bothered by pests like the four-line beetles, striped and spotted cucumber beetles, squash bugs, and aphids.

Hand-pick or spray them off with a stream of plain or soapy water; or ammonia-water solution.

Harvesting Pumpkins

A uniformly bright orange color (except for the mottled or white variety), tough skin, and shriveling vines are signs of a ready-to-harvest pumpkin.

Using shears, cut the stem, leaving a few inches at the top of the pumpkin fruits—to help prevent them from going bad too quickly.

Store them in a cool, dry place and enjoy them throughout the winter season!
