Summer and winter squash comes in an astonishing array of shapes, colours and sizes due to their ability to hybridise easily. Winter squash refers to all pumpkins and squashes with tough skin and delicately sweet flesh. Summer squash, including courgettes (or zucchini), are different varieties that are harvested young, whilst the skin and seeds are still tender.

Both summer and winter squash are native to America and belong to the large Cucurbitaceae or gourd family (also known as cucurbits). They were introduced in Europe during the 16th century. The plants are generally annual vines that use tendrils for support. They are monoecious, meaning that both male and female flowers are produced on the same plant. Female flowers are easily identified by an inferior ovary located at the base of the flower, which will become a fruit when pollinated. The edible male squash blossoms are often harvested after pollination then fried or stuffed. The female flowers are edible too, however picking them will of course result in fewer fruits. Squash is a very versatile vegetable that is delicious roasted, in gratin or blended into delicious soups. Courgette is a staple ingredient in ratatouille, couscous and many other popular Mediterranean dishes. Both courgette and squash are low in calories and high in minerals and vitamins, especially provitamin A and vitamin B.

Harvesting: Squashes should preferably be harvested at full maturity, unless they are liable to rot when left on the plant. If this is the case, they can be brought indoors to finish their maturation. Courgettes are harvested whilst they are still young and tender. Handle summer and winter squash with care to avoid damaging the skin.

Storage: Courgettes do not store well because of their fine skin. It is possible to freeze them in slices for later use. Thick-skinned winter squashes will keep for several months and can be eaten all winter long. Unlike other fruits and vegetables, they store better in a warm, dry place. No need to store them in the dark: they are great to decorate the house during the colder months!

Good to know: Placing the squash fruits on top of a slate or roof tile will keep them from being in direct contact with the ground. This prevents them from rotting due to excessive humidity. Squash and courgette plants favour moist soil and benefit from mulching, especially during the hotter summer months. Both are very prone to powdery mildew (a fungal disease that causes a white down to form on the surface of the leaves). When watering, try to avoid getting water on the leaves or flowers. Grow your squash plants alongside alliums such as chives, onions or shallots or members of the Fabaceae family (formerly legumes) such as beans or peas. Avoid growing them next to cucumber plants.

Even if the vegetable garden is first and foremost a place for growing great quality veg, it’s always a good idea to leave a bit of room for flowers. Growing flowers alongside your vegetable plants will make your general gardening experience more enjoyable and is a great way to attract pollinators and repel garden pests! Flowers such as gaillardia, marigolds, zinnias, cosmos or nasturtiums can be sown in and around the rows of vegetables. Herbs such as dill can be very useful also. Bear in mind that some companion plants self-seed easily and can be a bit invasive (borage, chives, lemon balm etc.)

NB: This variety is marked F1 for "F1 hybrid" meaning that its qualities are derived from carefully selected parent plants. This results in a variety that is both full of flavour and resistant to diseases. Sometimes criticized or wrongly assimilated to GMOs, F1 hybrid seeds have the advantage of producing reliable, uniform, disease resistant plants. Unfortunately, these qualities will not be passed on to following generations.
