Description
The Pumpkin or 'Uchiki Kuri' Potimarron is an excellent variety, productive and early. A climber, it produces about 5 fruits per plant, medium-sized (12 to 22 cm (5 to 9in), 1.2 to 1.5 kg) in the shape of a pear, Red orange, their thin and tender skin reveals a thick flesh with a delicious chestnut taste. This Potimarron benefits from excellent storage.
The 'Uchiki Kuri' Potimarron belongs to the Kabocha group, a cultivar of Japanese origin within the species Cucurbita maxima. Pumpkins, potimarrons and giraumons belong to the cucurbitaceae family. This herbaceous annual plant has long, vigorous, sprawling or climbing stems with the help of strong tendrils. Each plant has separate male and female flowers; it is the female flowers that will produce the fruits once fertilized by the pollen from the male flowers.
They come in many shapes and colours, from large ribbed orange or red fruits with orange flesh, to oblong shapes, pear shapes or "Turkish hat" shapes. Originally from South America, this species is said to have been introduced to Europe in the 16th or 17th century. They are often mistakenly called "pumpkins" when they actually belong to a different species, Cucurbita pepo, with fibrous and hard peduncles. As for the pumpkin, it has a sweet, tasty and less fibrous flesh with a tender and spongy peduncle.
Pumpkins are rich in vitamins and trace elements in addition to being low in calories, rich in potassium and having antioxidant properties.
Harvest and storage
Harvest the squash as late as possible, without risking the first frosts. Keep the peduncle as large as possible and store them in a temperate room (10 to 15°C (50 to 59°F)). This way, you can keep them for a few months to a year, avoiding them touching each other.
Gardener's tips
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 for example, between the ground and the fruit to isolate it and limit premature rotting. A thick mulch will also do the trick.

Planting and care
Preparation:
Cucurbitaceae, like a rich and deep soil. Dig a hole of 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 and plenty of space (at least 1 square meter).
Planting:
Planting in open ground is done from mid-May to mid-July, when the risk of frost is eliminated and the soil is sufficiently warm. Space the plants one meter apart in all directions. Soak the plants in water for a few moments before planting. Dig a hole 20 cm (8in) in all directions and place compost at the bottom. Install your plant with the grafting point at ground level, without burying it, and cover with soil. Firm and water well.
Maintenance:
Hoe and weed at the beginning of cultivation. We recommend mulching the soil towards the end of June with thin successive layers of mowing, mixed if possible with dead leaves. This protection, which allows the soil to remain moist, also reduces weeding. During cultivation, water regularly and abundantly (once a week in summer if there is mulching).
Finally, you can protect young plants from slugs and snails by placing ash or coffee grounds nearby, to be renewed in case of rain.
Running varieties need to be pinched. When the plant has 4 or 5 leaves, cut the stem above the first two leaves. Then cut the secondary stems again, after the formation of 3 or 4 fruits.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- 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.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
