Deep Orange Winter Squash

Uchiki Kuri is easily recognised by its beautiful deep orange skin. The fruits develop a rich, warm colour that makes this variety particularly attractive at harvest time.

Inside, the fruits have creamy yellow flesh, creating a beautiful contrast with the intensely coloured skin.

At approximately 1.5 kg per fruit, Uchiki Kuri is a practical size for home cooking while also being attractive for fresh-market sales and farm shops.

Vigorous and Productive

Uchiki Kuri is a vigorous-growing and highly productive variety that performs well under a range of growing conditions.

Plants develop strong trailing vines and should be given sufficient space to spread. A warm, sunny position, fertile soil and regular watering encourage strong growth and good fruit development.

Its reliable productivity makes Uchiki Kuri suitable for both home gardeners and professional growers.

Excellent for Culinary Use

Uchiki Kuri is primarily recommended for culinary use.

The creamy yellow flesh can be used in a wide range of autumn and winter dishes, including roasted squash, soups, purées, curries, risotto, casseroles and other cooked dishes.

The approximately 1.5 kg fruit size is especially convenient for household use.

Attractive for Autumn Displays

The intense orange skin also gives Uchiki Kuri excellent decorative value.

Freshly harvested fruits are attractive for autumn arrangements, harvest displays and seasonal decoration, while remaining first and foremost an edible winter squash.

Sowing Uchiki Kuri Seeds

Sow in May, according to local growing conditions.

In cooler climates, start seeds indoors or under protection. Sow 1 seed per pot or large plug cell in a fertile, well-drained seed-starting mix.

Cover the seed with substrate and keep evenly moist during germination without waterlogging.

After germination, provide seedlings with plenty of light. Squash plants grow quickly, so avoid keeping them in small pots for too long.

Transplant outdoors only after all danger of frost has passed and the soil has warmed.

Growing Conditions

Choose a warm, sunny position with fertile, well-drained soil.

Winter squash benefits from nutrient-rich soil. Before planting, incorporate well-rotted compost or other organic matter where needed.

Water regularly, particularly during flowering, fruit set and fruit development.

As Uchiki Kuri is vigorous and trailing, allow sufficient space between plants for healthy growth and good air circulation.

Harvest

The main harvest period is September to October.

Allow the fruits to mature fully and develop their characteristic deep orange skin.

Cut mature fruits from the plant using a clean knife or secateurs, leaving part of the stem attached. Handle the fruits carefully to avoid damaging the skin.

Harvest fruits intended for storage before frost.
