Description
The Orange Summer F1 squashis a premium hybrid variety, renowned for its great uniformity, yield, earliness, and resistance to powdery mildew. Its semi-bushy habit, more compact than that of trailing varieties, allows it to be grown even in raised vegetable beds. Its cultivation is suitable for market gardeners.
Each Orange Summer F1 squash plant produces several regular fruits, weighing 1.2 to 1.6 kg. Their smooth, shiny, bright orange skin protects thick, fine, and melting flesh. Sweet and sugary, it recalls the delicate flavour of chestnuts and lends itself to many culinary preparations.
Orange Summer F1 has a short cycle (85 to 90 days) and good resistance to powdery mildew. Its fruits can be harvested from the end of summer, well before the first frosts. And they can be stored for up to four months after harvest while retaining their flavour. This squash is very versatile in the kitchen, suitable for both savoury dishes and sweet recipes. Its creamy flesh adds sweetness and body to soups, pairs perfectly with spices in curries, and is ideal for gratins, tarts, or even cakes. Nutritionally, it is rich in beta-carotin (provitamin A), vitamin C, fibre, and minerals such as potassium and magnesium. It is low in calories and rich in antioxidants.
Orange Summer F1 squash belongs to the Cucurbita maxima group, a species native to South America introduced to Europe in the 16th century. This modern hybrid has been selected as an improvement on the famous Japanese 'Uchiki Kuri', retaining its delicate flavour while providing more regular production and simplified cultivation. Like all cucurbits, it is an annual herbaceous and monoecious plant, bearing both male and female flowers pollinated by insects to produce fruit.
Harvest squashes as late as possible, when the stalk becomes corky, and the foliage dries out. It is advisable to keep a thick stem to improve the fruit's keeping quality. Stored in a temperate room (10 to 15 °C), dry and without direct contact with each other, they can easily be kept for up to four months.
Orange Summer F1 squash likes rich, well-drained soil and a sunny position. Respecting a spacing of about 40 cm between two young plants in the row and 2.50 m between rows promotes good aeration and optimal fruit development.
As with all cucurbits, burying the stems at the node level stimulates rooting and strengthens the vigour of the young plants.
A thick organic mulch helps maintain moisture and limit weeds. To protect the fruits, it is recommended to keep them off the surface of the soil using a tile or a board to avoid any risk of rot.
The designation F1 indicates that it is a first-generation hybrid, resulting from the cross-breeding of two lines carefully selected for their complementary qualities. This produces plants with enhanced performance.
However, it is not advisable to harvest the seeds for resowing the following year: they would not produce young plants identical to the original variety, but very variable and generally less interesting subjects.

Planting and care
Orange Summer F1 Squash prefer loose, rich, and deep soil. Dig a hole at least 40 cm in all directions and fill it with well-rotted manure and/or compost. In addition to good fertilisation, they will need plenty of water and warmth and a lot of space (at least 1 square metre).
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), from March, sow 2 or 3 seeds per pot or container large enough for root development. Germination will occur 3 to 5 days later. Then keep only the most vigorous young plant. Plant out in the open ground after mid-May, once all risk of frost has passed. It is important not to sow too far in advance, as the young plants could become leggy and/or their overly developed root system might not withstand transplantation.
Or - from mid-May, directly in their final position, in stations of 3 seeds, as soon as frosts are no longer a concern and the soil is well warmed. Thin out after 2 to 3 weeks to keep only the most vigorous young plant. Cover the soil with organic matter (compost, grass clippings, leaves...), which will help keep the soil moist.
Watering:
From sowing or planting, water copiously, taking care not to displace the seeds, then regularly during fruit formation. However, once the fruits have 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).
