#13. Planting White Pumpkins

Since white pumpkins grow just before the onset of winter, they can be grown almost everywhere. Here is some information you need to know before planting white pumpkins.

How to Plant​?

Plant the white pumpkin seeds in a mound of soil to avoid waterlogging if you live in a region with high rainfall. But if you are living in a windy area, you should consider planting seeds in ditches to block the breeze.

When to Plant​?

For gardeners residing in areas with a warmer climate, consider planting the seeds outdoors. On the other hand, residents in cooler areas should plant the seeds indoors.

You must keep in mind that this plant cannot grow in harshly cold climates, and any temperature fluctuating 70 degrees F during the day and 55 degrees F at night is suitable for the plant to grow.

When to Plant​

Where to Plant?

The white pumpkin plant needs to be grown on well-drained soil that has significant water retention properties. Remember, dry soils do not work for pumpkins. Also, the type of soil you choose will determine the shade of the pumpkin.

Pro Tip: Some pumpkins need shade to maintain their white color. Try leveling your soil readily since it assists in forming a pleasingly round shape. On the contrary, if not leveled, ugly-looking lumps might form on the pumpkins.

How to Take Care of White Pumpkins?

All varieties of pumpkins have different preferences for their growth requirements. Yet, white pumpkins have a few peculiar demands that gardening aspirants must be aware of. Here are few ideal growing conditions for white pumpkins to thrive in:


The types of white pumpkins mentioned above have their particular requirements to maintain that silvery gleam. For example, polar bear pumpkins need sunlight after harvesting, while Full Moon pumpkins need shade to stay white.


You can select what type of white pumpkin you want to grow according to the sunlight intensity in your area and the shaded areas in your backyard. In general, white pumpkins need to stay in the sun for eight hours each day.


The fertilizer needed for white pumpkins depends on their type. At the same time, it is necessary to use organic fertilizers on your white pumpkins regularly to help them grow evenly and keep their color consistent.

Be warned! Spreading excessive fertilizer might mess with the pigments of your pumpkins. This affects the taste, size, and desired shape of the fruit.

Maintaining an effective drainage system for your pumpkins can help them grow better. Before planting white pumpkins, it is better to check the type of soil you have in your garden and the water balance it possesses to help the plant stay healthy. Once figured, start watering the pumpkin plant by 1-inch each week.


Since they need healthy watering cycles, they begin by mid-July. And for best results, continue watering them on alternate days till they radiate a matured look.

Pro Tip: White pumpkins grow in size as they age. A greater thirst for water accompanies this size growth. You know the drill!

For all your gardeners living in dryer areas, opt for everyday watering cycles.

Another solution is adding mulch to maintain water balance in the soil.

Caution! Watering white pumpkins through the hose makes them likely to develop rot and not grow. Make sure you stick to watering through a can.

Depending on the type of pumpkin you want to grow, you need to adjust the space between each pumpkin accordingly. Usually, the larger the pumpkin, the bigger space it will need.

Anything north of a square foot for one pumpkin is the ideal spacing. And for a bulky harvest, try planting the pumpkins in a hilly format rather than in rows.

For DIYers growing pumpkins through seeds, shove each seed 1 and 1/2 inches deep while maintaining a distance of 6 inches between each plant.

Pro Tip: Looking for the best of both worlds? Plant a combination of pumpkin varieties—for example, one for edible pumpkins and one solely for decorative pumpkins.

Companion Planting​

Companion planting is a gardening technique where a suitable combination of fruits or vegetables is grown together. The point being, they grow well when sharing common soil, feeding on common nutrients, and helping each other survive.

In the case of pumpkins, consider indulging in companion planting through radicchio, squash, marigolds, or tomatoes.

Since bees are necessary to pollinate white pumpkins, choose plants like bee balm and lavender that attract bees to your garden if you’re worried about other pests, plant sunflowers to shoo away the ones that threaten your white pumpkins.

Here are some tips that should help with your DIY gardening efforts.

Harvesting Tips for Pumpkin Fruit​

Owing to their bland taste, these pumpkins are also known as ghost or snow pumpkins. Though they’re low maintenance and grow no more than 4 feet in height with a bushy look, you could benefit from some harvesting tips.

⦁ Make sure to track how long it takes for your type of pumpkin to mature. If left for too long, the skin of the pumpkin may lose its sheen and begin rotting.
⦁ Check if the skin remains intact when you make a small slit with your fingernails. If it does, then the fruit is ripe and ready for harvesting.
⦁ It is better to use a knife to cut the fruit from the stem while harvesting. Ripping the vine off might leave a ragged branch which can shorten the life of the pumpkin plant.
⦁ You need to store the white pumpkins in dry, cool, and shaded places. Some variants, like the Polar Bear pumpkin, need sunlight for freshness.

Harvesting Tips for Pumpkin Seeds

Pumpkin seeds boast an epic nutritional composition of vitamins and minerals such as manganese, zinc, phosphorus, and vitamin K. Make the most of your pumpkin plant and ensure you harvest the seeds properly. You’ll be equipping your immune system to deal with deadly viruses, bacteria and also quicken wound-healing durations. Here are some tips to follow:

⦁ Rinse the seeds after separating them from the pulp and place them on a towel to dry for about a week.
⦁ If using the seeds for planting, store them with other seeds or in the refrigerator.
⦁ If using the seeds for eating, roast them before consumption.

Threats to Your White Pumpkins

When it comes to threats in gardening, pests, and insects are the biggest problem to any plant. Here are some of the common pests that can ruin your white pumpkins:


Aphids consist of tiny green or white bugs, which are one of the smallest, but dangerous pests for plants. They can quickly feed on the leaves and fruits and cause immense harm to the plant.

To control these pests from destroying your white pumpkins, spraying water at high speeds can help protect the plant. But, it would help if you did it as soon as you spot any aphids.

Pro Tip: Introducing ladybirds can also help control the threat.


Two types of beetles can cause harm to your pumpkins, namely cucumber beetles and squash bugs. You can simply pick them and drown them in a tub of ammonia mixed with soapy water.


Also, using sunflowers helps as a distraction since beetles are more likely to feast on sunflowers than pumpkins.

Powdery Mildew​

Powdery mildew can live in the soil and destroy the roots of plants. Using fungicide can help end the threat. Also, crop rotation proves effective in curbing infection of plants through the soil.

Zucchini Yellow Mosaic Virus​

There are many viruses, namely the Zucchini Yellow Mosaic Virus, which aphids can transfer to pumpkin plants as mentioned above. A fungicide can curb the virus, though it might not be effective enough. Instead, plant virus-resistant varieties of white pumpkins to ensure no viral diseases on pumpkins.

Zucchini Yellow Mosaic Virus​

Weeds can also affect the plant and cause an infection. Using a weedicide can kill the growth of weeds near your plants.


Feel free to mix a little salt with water and spray on the infected sections of the plant. This mixture is an excellent pest-repellent and will keep your plant pest-free.

All in all, white pumpkins aren’t too hard to grow, provided you abide by their sunlight, watering, soil, and fertilization requirements. The luster on white pumpkins makes the fruit look beautiful, eventually adding an ornamental plant to your garden.
