Meet Ghost Pumpkin
A striking white-skinned pumpkin variety also known as Lumina, producing smooth, ghostly pale fruits perfect for autumn decoration. The flesh is bright orange despite the white exterior and makes excellent pies, soups, and purees. Fruits weigh 10 to 15 pounds and store well in a cool, dry location for several months. The stark white surface also makes an ideal canvas for painting or carving unique Halloween displays.
When to plant Ghost Pumpkin
Start ghost pumpkin seeds indoors 3-4 weeks before the last frost in individual biodegradable pots, as pumpkins dislike root disturbance. Plant seeds 1 inch deep in warm starting mix at 75-85°F. Seeds germinate in 7-10 days. Harden off seedlings for a week before transplanting after all frost danger. For direct sowing, wait until soil is 65°F or warmer and plant 1 inch deep with 3-4 seeds per hill. Thin to the 2 strongest seedlings. Seeds remain viable for 4-6 years when stored in cool, dry conditions.

How to grow Ghost Pumpkin
Ghost pumpkins (Lumina) need a long, warm growing season of 100-115 days and plenty of space for their sprawling vines. Start seeds indoors 3-4 weeks before the last frost, or direct sow after soil temperatures reach 65°F. Plant seeds 1 inch deep in mounds spaced 6-8 feet apart, placing 3-4 seeds per hill and thinning to the 2 strongest. Vines spread 15-20 feet and need generous room to grow.
Provide consistent moisture with 1-2 inches of water per week, using drip irrigation or soaker hoses to keep foliage dry. Apply a balanced fertilizer at planting and switch to a higher phosphorus and potassium formula when flowering begins. Side-dress with compost monthly during the growing season. Mulch generously around plants to suppress weeds and retain moisture.
For the best white color, place a board or thick straw pad under developing fruits to prevent contact with soil, which can cause yellowing or staining of the pristine white skin. Hand pollination in the early morning improves fruit set. Limit each vine to 2-3 fruits for the largest, most uniform pumpkins. As fruits mature, reduce watering gradually to concentrate sugars in the flesh and toughen the skin for storage.

Ghost Pumpkin's best neighbours
Ghost pumpkins benefit from the Three Sisters planting method with corn and beans. Corn provides a windbreak, beans fix nitrogen, and the large pumpkin leaves shade soil to conserve moisture and suppress weeds. Marigolds and nasturtiums planted around the perimeter deter squash bugs and cucumber beetles. Radishes planted near hills may deter vine borers. Avoid planting near potatoes or other heavy-feeding root crops. Sunflowers attract pollinators that improve fruit set.
Corn belongs beside it. Potato doesn't.

Feed it well
Ghost pumpkins are heavy feeders requiring rich, well-drained soil with a pH of 6.0-7.0. Prepare mounds with generous amounts of compost or aged manure, ideally 3-4 shovelfuls per hill. Apply a balanced 10-10-10 fertilizer at planting, then switch to a phosphorus and potassium-heavy formula (5-10-10) at flowering. Side-dress with compost every 3-4 weeks. Pumpkins are particularly responsive to foliar feeding with fish emulsion or seaweed extract. Maintain adequate calcium to prevent blossom end rot.
Ideal Temperature
Hardiness Zone Compatibility
From seed to harvest, stage by stage
Seed Starting
Large, flat seeds germinate in warm soil, sending up a thick hypocotyl that pushes two broad cotyledon leaves above the surface. Germination requires soil temperatures of at least 16°C (60°F) and takes 5-10 days. Seeds planted in cold, wet soil are prone to rot before emerging.
Seedling Growth
True leaves emerge with the characteristic deeply lobed pumpkin shape. The stem thickens rapidly and the first tendrils appear, signalling the plant is preparing to vine. Root systems develop extensively during this stage, establishing the foundation for a vigorous plant.
Vine Extension
Vines begin their aggressive sprawl, extending 15-30 cm per day in warm conditions. Secondary vines branch off the main runners, and the large, rough-textured leaves form a dense canopy that shades out weeds. Tendrils grip anything they contact for support.
Flowering
Male flowers appear first in clusters, followed by female flowers 7-10 days later. Female flowers are easily identified by the small round swelling (the ovary) at their base, which appears pale green to white. Each large golden-yellow flower opens at dawn and closes by midday, giving pollinators a narrow window.
Fruit Development
Successfully pollinated fruits swell rapidly, growing visibly larger day by day. The skin transitions from pale green to creamy white as the fruit matures. Each vine typically supports 2-4 large fruits. The rind hardens progressively, developing the smooth, porcelain-like finish that defines the variety.
Harvest
Fruits are ready when the rind is uniformly ivory-white, hard enough to resist a fingernail scratch, and the stem has turned dry and corky. The vine begins to yellow and die back naturally. Mature ghost pumpkins weigh 4-7 kg and have a solid, heavy feel relative to their size.
Sow seeds 2.5 cm deep in warm soil or start indoors 3-4 weeks before last frost using large pots. Maintain soil temperature at 21-27°C (70-80°F) for fastest germination. Avoid overwatering during this stage.

Harvesting Ghost Pumpkin
Harvest ghost pumpkins when the skin is fully white and hard, the stem has turned brown and corky, and the tendril nearest the fruit is dry and brown. This typically occurs 100-115 days after planting. Test maturity by pressing a fingernail into the skin; mature pumpkins will resist denting. Cut from the vine with a sharp knife leaving 3-4 inches of stem attached, as stemless pumpkins rot faster. Avoid carrying by the stem as it can break. Cure in a warm, sunny spot for 10-14 days to harden the skin before long-term storage.

Storage & Preservation
Properly cured ghost pumpkins store for 3-6 months in a cool, dry location at 50-55°F. The white skin should remain clean and unblemished for best storage life. Once cut, wrap remaining portions in plastic and refrigerate for up to a week. Cooked pumpkin puree freezes well for up to 12 months and makes an excellent pie filling. Pumpkin can be cubed, roasted, and frozen in portions. Seeds are edible when roasted with oil and salt. For decorative use, sealed and shellacked ghost pumpkins can last several months as displays.
What goes wrong — and the fix
Squash Vine Borer
PestSudden vine wilting, sawdust-like frass at stem base, fat white larvae tunneling inside hollow stems.
Powdery Mildew
DiseaseWhite powdery patches covering leaves and stems, premature leaf death, reduced fruit size and sweetness.
Squash Bug
PestBrown shield-shaped bugs clustering under leaves, wilting foliage, copper-colored egg clusters on leaf undersides.
Bacterial Wilt
DiseaseRapid wilting of individual vines, sticky bacterial ooze when stems are cut, entire plant death within days.
Troubleshooting Common Problems
The white skin, while beautiful, shows every blemish, soil stain, and scratch more visibly than orange pumpkins. Placing fruits on clean straw or boards prevents soil contact staining. Squash vine borer is devastating in eastern North American gardens. Insufficient pollination causes small, lopsided fruits. Powdery mildew typically arrives in late summer and shortens the vine life. Overwatering near harvest time dilutes flavor and reduces storage quality. Frost exposure before harvest damages the white skin with brown spots.
Growing Tips
- Build compost-enriched mounds for planting — ghost pumpkins are heavy feeders that demand rich, well-drained soil. Work in a full wheelbarrow of compost per planting hill and top-dress with aged manure for best results.
- Space aggressively. Each ghost pumpkin plant needs 3-5 square meters of growing space. Crowded plants produce fewer, smaller fruits and are far more susceptible to powdery mildew from poor air circulation.
- Pollination is the number one cause of crop failure. If bees are scarce in your garden, hand-pollinate every morning between 6-10 AM by dabbing a small brush inside male flowers and transferring pollen to the sticky centre of female flowers.
- Limit each vine to 2-3 fruits for the largest, most impressive pumpkins. Once the desired number of fruits have set, pinch off new female flowers and trim vine tips to redirect all the plant's energy into the existing fruits.
- Elevate developing fruits off the ground using tiles, boards, or straw pads. Direct soil contact invites rot, slugs, and discolouration on the bottom of the fruit — especially problematic for white-skinned varieties where blemishes are highly visible.
- Water deeply at the base using drip irrigation or soaker hoses, never overhead. Wet foliage is an open invitation for powdery mildew, the most common disease affecting ghost pumpkins. Water in the morning so any splash dries quickly.
- Apply a preventative spray of diluted milk (1 part milk to 9 parts water) weekly to foliage to suppress powdery mildew. This folk remedy has been validated by research and is remarkably effective when started before symptoms appear.
- Harvest timing is critical for storage life. Wait until the rind is rock-hard and the stem is completely dry and corky. Premature harvest leads to soft spots and dramatically shorter storage life.

Where Ghost Pumpkin comes from
White pumpkins have a long history intertwined with the broader story of Cucurbita maxima, the species to which most ghost pumpkin varieties belong. Pumpkins and squashes were among the earliest domesticated crops in the Americas, with archaeological evidence of cultivation in Mexico dating back over 7,000 years. Indigenous peoples across North and Central America developed an extraordinary diversity of squash varieties over millennia, including pale and white-skinned forms that were valued both for eating and for ceremonial purposes.
The modern ghost pumpkin as a distinct ornamental and culinary variety gained popularity in the late 20th century. The Lumina variety, bred and introduced in the 1990s, was one of the first widely available pure-white pumpkins marketed specifically for decoration. Its smooth, porcelain-like skin and reliable white colour made it an instant hit for autumn displays and Halloween decorating. Other white varieties including Casper, Cotton Candy, and Snowball followed, each offering slight variations in size, shape, and flesh quality.
Today, ghost pumpkins have moved well beyond decoration. Chefs and home cooks have discovered that many white varieties have dense, sweet, bright-orange flesh that is superior to common carving pumpkins for cooking. The contrast between the ghostly white exterior and the rich orange interior has made them a favourite at farmers markets and in farm-to-table restaurants. Commercial production has expanded significantly across North America and Europe, where they command premium prices both as decorative items and as culinary pumpkins. Seed companies now offer dozens of white pumpkin varieties ranging from miniature ornamentals to large cooking types, reflecting a growing appreciation for these striking fruits.
