Pie Pumpkin

Cucurbita pepo

History & Nutrition

History

Pie pumpkins represent the original culinary purpose of American pumpkins—small, sweet-fleshed fruits grown specifically for eating rather than decoration. While Native Americans cultivated pumpkins for millennia, the distinction between "pie" and "carving" varieties developed after European colonization, as gardeners selected for different traits. The New England Pie Pumpkin, documented as early as 1863 in American seed catalogs, became the gold standard for baking—its dense, fine-grained, non-stringy flesh producing smooth, sweet purees without the watery quality of larger field pumpkins. Interestingly, what most Americans know as "canned pumpkin" is actually made from Dickinson squash—a Cucurbita moschata variety more closely related to butternut squash, grown commercially by Libby's since 1929. This commercial reality has caused confusion, but home gardeners growing true pie pumpkins like Sugar Pie, New England Pie, or Long Island Cheese discover flavors superior to anything canned. The Long Island Cheese pumpkin, named for its resemblance to a wheel of cheese, has been grown since at least the 1800s and was the pumpkin most commonly used in early American cooking. These compact 4-8 pound fruits yield approximately 2-3 cups of puree each, perfect for a single pie. The resurgence of interest in heritage foods has brought renewed attention to pie pumpkins, with farmers' markets now featuring multiple varieties each fall. Making pumpkin puree from scratch requires simply roasting, scooping, and pureeing—a simple process that yields results far superior to commercial canned products.

Humidity

50-70%

Moderate humidity ideal. Good air circulation reduces powdery mildew and other fungal diseases.

Plant Size & Growth

Height

12-18 inches (sprawling vine)

Spread

10-15 feet

Growth Habit

vine

annualRoot Depth: Extensive root system with shallow feeder roots spreading wide and tap roots to 24-36 inches.
Growth Stages

Germination

5-10 days

Seed coat splits, cotyledons emerge and unfold. Fastest in warm soil (85°F).

Seedling Stage

Duration: 2-3 weeks

True leaves: First true leaves are rounded with scalloped edges, developing after cotyledons

Transplant ready: Ready to transplant when 2-3 true leaves developed and roots fill cell

Vegetative Growth

Duration: 4-6 weeks

Vines extend rapidly, large lobed leaves develop, plant establishes extensive root system.

Flowering

Timing: 6-8 weeks after planting

Duration: 4-6 weeks

Requires bee pollination; male flowers appear first, female flowers have small fruit at base

Fruit Development

Begins: 8-10 weeks after planting

Duration: 6-8 weeks to maturity

Fruit swells rapidly, skin hardens, color deepens to rich orange

Harvest Maturity

Timing: 90-110 days from seed

  • Deep, uniform orange color
  • Hard rind that resists fingernail
  • Dry, corky stem
  • Hollow sound when tapped
Expected Yield

Per Plant

2-5 pie pumpkins (4-8 lbs each)

Per Square Foot

2-4 pumpkins per 15 square feet of vine

Harvest Frequency

Single harvest in fall

Factors Affecting Yield

  • Pollination success
  • Water consistency
  • Soil fertility
  • Growing season length
Watering Guide

Seedling Stage

Keep consistently moist, water daily if needed

Established Plants

1-2 inches per week, deep watering preferred

During Fruiting

Maintain consistent moisture; reduce slightly as fruit matures

Preferred Method

Drip irrigation or soaker hose at soil level

⚠️ Critical Watering Periods

  • Flowering
  • Fruit development

Pro Tips

  • Water at base of plant, not on foliage
  • Morning watering allows leaves to dry before evening
  • Mulch heavily to retain moisture
  • Inconsistent watering causes misshapen fruit
  • Reduce watering 1-2 weeks before harvest to concentrate sugars
Fertilizing Guide
moderate feederRecommended: 5-10-10 during fruiting, balanced during vine growth

Feeding Schedule

Pre-planting

Compost and balanced organic fertilizer

Once at soil preparation

Vine development

Balanced fertilizer (10-10-10)

Every 2-3 weeks

Flowering/Fruiting

Low-nitrogen, high-phosphorus fertilizer

Every 2-3 weeks

Organic Options

CompostFish emulsionBone mealKelp meal

Side-dress with compost when vines begin to run. Reduce nitrogen once flowering begins.

Container Growing
✓ Suitable for containers

Minimum Size

15 gallon minimum

Recommended Size

20+ gallons for best results

Depth Required

At least 12 inches deep

Container Tips

  • Choose compact or bush varieties when available
  • Allow vines to trail over edges or grow on trellis
  • Water more frequently than in-ground plants
  • Limit to 1-2 fruits per container plant
  • Use support slings for developing fruit if vining vertically
Support & Trellising
Support Optional

Support Type

A-frame or sturdy vertical trellis, 6-8 feet tall

Height Needed

6-8 feet

When to Install

Install at planting time before vines develop

Method

Train main vine up trellis. Use fabric slings to support developing pumpkins (5+ lbs each). Allow secondary vines to trail.

Tips

  • Saves garden space and improves air circulation
  • Use fabric slings to support developing pumpkins
  • Ensure trellis can support 15-20 lbs total fruit weight
  • Train main vine up, allow secondaries to trail

Pruning Guide
Pruning Optional

Why Prune

Direct energy to developing fruitImprove air circulationLimit vine spread

When

After fruit set, when 2-3 pumpkins are developing

Technique

Pinch off vine tips beyond developing fruit. Limit to 2-3 fruits per vine for larger pumpkins.

Remove

  • Excess developing fruit
  • Secondary vines if space limited
  • Vine tips after adequate fruit set

Keep

  • Main vine
  • Selected fruits
  • Plenty of foliage for photosynthesis
