Description
The Gel Reuzen Pumpkin, also known as the Yellow Quintal, is a vigorous climbing variety, originally from Germany, that produces large yellow-orange fruits weighing on average 30 to 60 kg but can reach up to 150 kg. The flesh is edible but becomes fibrous and spongy.
Pumpkins, potimarrons, and giraumons belong to the Cucurbitaceae family and the species Cucurbita maxima. This annual herbaceous plant has long, vigorous, climbing or trailing stems with strong tendrils. Each plant has separate male and female flowers, making it monoecious; it is the female flowers that will develop into fruits once fertilized by the pollen from the male flowers.
They come in many shapes and colors, from large ribbed orange or red fruits with orange flesh, to oblong shapes, pear shapes, or even "Turkish hat" shapes. Native to South America, this species is said to have been introduced to Europe in the 16th or 17th century, along with its cousins, other species of Cucurbita. They are often wrongly called "pumpkins" even though they belong to a different species, Cucurbita pepo, with fibrous flesh and a hard, fibrous stem. Pumpkins, on the other hand, have sweet, flavorful flesh with a tender, spongy stem.
Pumpkins are rich in vitamins and trace elements, low in calories, high in potassium, and have antioxidant properties.
Harvest and storage
Harvest the squash as late as possible, without risking the first frost. Keep the stem as large as possible and store them in a temperate room (10 to 15°C). This way, you can keep them for a few months to a year, making sure they don't touch each other.
Gardening tips
You can bury the stems at the nodes to encourage rooting.
To save space and protect your fruits from rot, you can grow pumpkins on supports such as a trellis or sturdy stakes.
During fruit ripening, you can place a tile, a brick, or any other object between the fruit and the ground to isolate it and prevent premature rotting. A thick mulch will also do the trick.

Planting and care
Preparation
Cucurbitaceae plants like loose, rich, and deep soils. Dig a hole at least 40 cm (16in) in all directions and fill it with well-decomposed manure and/or compost. In addition to good fertilization, they will need plenty of water and heat, as well as plenty of space (at least 1 square meter).
Sowing
Before sowing, you can soak the seeds for 24 hours in a little water to stimulate germination.
Either, 3 weeks before transplanting, under a cold frame or in a warm place (16 to 30°C (60.8 to 86°F)), starting from March, sow 2 or 3 seeds per large enough bucket or container for root development. Germination will occur 3 to 5 days later. Then, keep only the most vigorous plant. Plant in the ground after mid-May, once all risk of frost has passed. It is important not to sow too early, as the plants could become weak and/or their root system, which is too developed, would not withstand transplantation.
Or, starting from mid-May, directly in place, in groups of 3 seeds, as soon as there is no longer any risk of frost and the soil is well warmed up. Thin out after 2 to 3 weeks, keeping only the most vigorous plant. Cover the soil with organic matter (compost, clippings, leaves...), which will help maintain the soil moisture.
Watering
From sowing or planting, water generously, taking care not to displace the seeds, and regularly during fruit formation. However, once the fruits are formed, during ripening, limit watering.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
