Strategic Planting Techniques:

Timing is crucial when planting giant pumpkins in the UK. Start seeds indoors around April, allowing them to germinate in a warm and controlled environment.

Transplant seedlings outdoors when the risk of frost has passed. Provide ample space between plants to accommodate their expansive vines and sprawling growth habit.

Nutrient-Rich Fertilization:

Giant pumpkins are voracious feeders, requiring a steady supply of nutrients for optimal development. Implement a regular fertilization schedule, incorporating balanced organic fertilizers.

Pay attention to potassium levels, as this nutrient promotes sturdy vine development and aids in fruit maturation. Mulching around the plants helps retain soil moisture and suppress weeds.

Pest Management and Disease Prevention:

Protect your giant pumpkins from common pests like aphids and squash bugs by regularly inspecting plants and applying organic insecticides when necessary.

Implement preventative measures against fungal diseases by spacing plants for proper air circulation and avoiding overhead watering. Swift action and vigilance are key to maintaining a healthy pumpkin crop.

Are pumpkins healthy? Yes they are!

Known primarily for its role as a Halloween decoration or a pie filling, pumpkins are also packed with nutrition and bring a wide range of health benefits.

Pumpkins are a storehouse of vitamins, minerals and other healthy nutrients. Whether it is the pulp or the seeds, pumpkins are great for your health and can offer some incredible benefits.

The pumpkin is one of the lowest-calorie vegetables, providing just 26 calories per 4oz. It contains no saturated fats or cholesterol, but is a rich source of dietary fibre, anti-oxidants, minerals and vitamins.

Pumpkin is a storehouse of many anti-oxidant vitamins such as vitamin A, vitamin C and vitamin E.

With 0.3oz per four ounces, it will provide about two and a half times your daily recommended dose of Vitamin A, a powerful natural anti-oxidant that is required by body to maintain the integrity of skin and mucus membranes. It is also an essential vitamin for vision.

Research studies suggest that natural foods rich in vitamin A also help to protect our bodies against lung and oral cavity cancers. Pumpkin is also rich source of minerals like copper, calcium, potassium and phosphorus.

Pumpkin seeds are good source of dietary fibre and mono-unsaturated fatty acids, which are good for cardiac health.

When and How to Sow Atlantic Giants

To grow Atlantic Giants, the champion of large pumpkins, start sowing seeds indoors in late April or early May.

Use large pots and a good-quality seed starting mix. Plant seeds 1 inch deep, with the pointed end facing down.

Keep the soil warm, ideally between 70-85°F (21-29°C), and maintain consistent moisture. Once seedlings develop true leaves and the risk of frost has passed, they are ready for outdoor planting.

When and How to Plant Out

Plant your Atlantic Giant pumpkins outdoors after the last frost, typically in late May or early June, depending on your climate.

Choose a sunny, well-drained location with ample space for vine growth. Harden off the seedlings by gradually exposing them to outdoor conditions over a week. Plant them in mounds of rich, fertile soil, spaced 8-10 feet apart.

Watering, Feeding, and Guiding the New Pumpkin Vine

Water the plants deeply and regularly, aiming for 1-2 inches per week. As the vine grows, start a feeding regime with a high-nitrogen fertilizer to encourage vine growth.

Gently guide the vines in the direction you want them to grow, but avoid excessive handling to prevent damage.

Burying the Vine and Mulching

Burying the vine at several points (by covering sections of the vine with soil) encourages secondary root growth, which can help with nutrient uptake and stability.

Apply mulch around the base of the plant to retain moisture, regulate soil temperature, and reduce weed competition.

Hand Pollinating

Hand pollination can increase the chances of fruit set. Once male and female flowers are present, use a soft brush or your fingers to transfer pollen from the male to the female flowers in the early morning. The female flower is distinguishable by the small fruit at its base.

Fruit Feeding & Foliar Feeding

Switch to a high-potassium, low-nitrogen fertilizer once fruits begin to form. Apply foliar feeds (liquid fertilizer applied to leaves) for additional nutrient uptake, but be cautious of overfeeding, which can damage the plant.

Losing / Shedding Pumpkins

It’s common for pumpkin plants to shed smaller or excess fruits. Focus on one or two pumpkins per plant to grow the largest possible pumpkin. Remove extra fruits to direct the plant’s energy to the chosen pumpkins.

Mildew and Pests

Regularly inspect plants for signs of mildew, pests, or diseases. Treat mildew with appropriate fungicides and manage pests through organic or chemical means as necessary. Maintain good air circulation and avoid wetting foliage to reduce disease risks.

Protecting Fruit from Sunlight

Direct sunlight can cause the skin of the pumpkin to harden prematurely, limiting growth. Use shade cloths or build a simple shelter to protect the fruit during the hottest parts of the day.

When to Harvest Giant Pumpkins

Harvest your Atlantic Giants when they have reached their desired size, typically in September or October, before the first frost. Look for a hard, sound skin and a deep, solid color. Cut the pumpkin from the vine, leaving a few inches of stem, and handle it carefully to avoid bruising.
