Premium Kabocha Squash with Excellent Flavour

DELICA® F1 belongs to the Kabocha group of winter squash, prized for dense flesh and excellent culinary qualities.

The fruits develop a distinctive dark green exterior and flattened, rounded shape, while inside they contain a generous layer of thick yellow flesh. The flavour is notably sweet and rich, making DELICA® an excellent choice when eating quality is a priority.

The dense flesh is particularly good for dishes where a rich pumpkin flavour and substantial texture are desired.

Excellent for Cooking

DELICA® F1 is a versatile edible squash suitable for a wide variety of recipes.

The sweet, dense flesh is excellent for oven roasting, baking, creamy soups, purées, curries, risotto and other savoury or sweet pumpkin dishes.

Roasting helps concentrate its natural sweetness, while the dense texture makes it particularly useful for recipes where a watery squash would be less suitable.

Reliable F1 Variety

One of the important characteristics of DELICA® F1 is its wide adaptability to different growing conditions.

The variety has been selected to produce first-class fruits of good size while maintaining excellent eating quality. This makes it suitable not only for gardeners looking for a high-quality Kabocha squash but also for growers who value uniformity, productivity and dependable crop performance.

When to Sow DELICA® F1

Sow from April to May, adjusting the exact timing to your local climate and growing conditions.

For an earlier start, sow seeds individually in pots or large cells under protection. Squash develops quickly and should not be kept in small containers for too long.

Plant outdoors only after the risk of frost has passed, when the soil has warmed and conditions are suitable for active growth.

In warmer conditions, seeds can also be sown directly into prepared soil once temperatures are sufficiently high.

How to Sow Cucurbita maxima Seeds

Sow 1 seed per pot or cell in moist, fertile and well-drained seed-starting compost.

Cover the seed with substrate and maintain consistent moisture during germination, avoiding waterlogged conditions.

After germination, provide seedlings with plenty of light to encourage strong, compact growth.

Before transplanting outdoors, gradually harden off young plants so they can adjust to outdoor temperatures, sunlight and wind.

Growing DELICA® F1

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

Pumpkins and winter squash are vigorous plants with high nutrient and water requirements. Incorporating well-rotted compost or other organic matter before planting can help improve soil fertility and moisture retention.

Water consistently, especially during flowering and fruit development. Whenever possible, water around the base of the plant rather than repeatedly wetting the foliage.

Allow sufficient growing space for the vines to develop freely.

Approximately 100 Days to Maturity

DELICA® F1 reaches maturity in approximately 100 days, although actual development time will vary according to temperature, sunlight, planting date and local growing conditions.

Warm summer conditions encourage vigorous growth and good fruit development.

For the best eating and storage quality, allow fruits to mature properly on the plant before harvesting.

Harvesting

Harvest when the fruits have reached their characteristic dark green colour and mature flattened shape, and the skin has become firm.

Cut the fruit from the plant rather than pulling it, leaving a section of stem attached.

Handle harvested fruits carefully. Damage to the skin can reduce storage quality.

If the fruits are intended for storage, harvest them before frost and allow them to dry properly before moving them into storage.

Storage

Winter squash is particularly valuable because mature fruits can be enjoyed well beyond the summer growing season.

Store healthy, undamaged fruits in a dry, well-ventilated and frost-free location. Avoid storing damaged fruits for extended periods and check stored squash occasionally.

Good growing, harvesting and storage conditions help preserve both fruit quality and flavour.

For Home Gardens and Professional Growers

DELICA® F1 combines qualities that are important for both small-scale and professional production: excellent flavour, attractive fruits, good size and adaptability to different growing conditions.

For commercial production, the breeder information indicates a planting density of approximately 15,000 plants per hectare. Home gardeners should simply provide each plant with sufficient room for vigorous vine development.
