Description

The  'Jim Jams' Gourds are climbing or creeping annual plants, they are Decorative Squashes. Beautiful as they are with their original shapes and their variegated colours, these Squashes are not edible. Their bitter flesh is used in herbal medicine for some of their medicinal properties but it is toxic if consumed directly.

 

 

Cucurbita pepo, in Latin, belongs to the large family Cucurbitaceae. Like all squashes, the gourds love rich and moist soils. So do not hesitate to provide them with plenty of water and well-decomposed compost or manure so that they can develop to the fullest and produce many fruits.

Most varieties are climbing. Their branches with tendrils will attach to the support that you have provided for them to best expose their fruits to the sun. If they do not have support, they will spread on the ground. Choose a warm and sunny location for them.

 

Harvested in September-October, before the first frost, the fruits will be detached while leaving a part of the fruit's peduncle. Stored in a warm and dry place, the flesh of the fruits will dry out in a few weeks. The mummified fruits can then be used for decoration in the house. The cultivation and abundant harvest of these colourful mini-pumpkins are a great opportunity to introduce children to gardening.

Planting and care

Sow 'Jim Jams' Gourds in mid-April in pots. Use good quality soil, possibly enriched with compost. Sow 2 to 3 seeds in each hole. Cover the seeds, lightly press down, and water generously with a fine rain. Place your pots in a well-lit area, without direct sunlight, at a temperature of 15 to 20°C (59 to 68°F).

 

The seeds will germinate in about 7 days. As soon as the plants have developed two beautiful leaves, pinch the top of the stem to cut it. This will force the formation of lateral branches. Repeat this process a few weeks later, above the fifth leaf. 15 days before their final planting, start gradually acclimatising them to a temperature of 15°C (59°F).

By late May or early June, the temperature in the garden will be warm enough to plant your young plants. Choose a sunny location. Add a good shovelful of compost to each planting hole. Space your plants 1 to 2m (3 to 7ft) apart.

Don't forget to provide them with support. This can be a trellis or even the low branches of an old tree.

Harvest the fruits in autumn before the first frost and let them dry before using them for decoration. During drying, wipe the fruits with a soft, dry cloth to remove any superficial mould that may appear.
