Our advice, your success!

Insect netting before pollination

Insect netting is recommended for all cucurbits to combat the striped cucumber beetle. Be careful, it will be necessary to remove the netting when the flowers form or opt for hand pollination.

Seed pre-germination; simple and effective

For optimal germination, we suggest pre-germinating in a warm, moist cloth before sowing. A temperature of 25°C gives the best results. As soon as the sprout appears, you can sow in a warmed-up position in the garden.

Indoor sowing; fragile roots

Cucurbits have very fragile roots. If you start your cucurbit seedlings indoors, be sure not to damage the roots when transplanting them into the ground. Using a biodegradable pot is recommended.

Courgette or zucchini

Summer squash, zucchini

Zucchini is a cylindrical fruit ranging from dark green to pale green, sometimes striped or marbled with spots
pale; some cultivars have a bright yellow color. Zucchini is eaten young, when the skin and flesh are tender, the seeds have not yet formed, and it is no more than 20 cm long. If a zucchini is left on the plant, the fruit quickly reaches 60 cm in length. At maturity, the fruit is edible, like a winter squash, but its flavor is bland and its flesh stringy; the skin and seeds must be removed.

Advice from the seed producer and author

Conditions for growing squash

Since squash are sensitive to frost, you must wait until the risk of frost has passed before sowing them.
As they come from tropical areas, they appreciate warmth. The optimal temperature for their growth is between 15 and 25°C, with the maxima species being best suited to cold conditions. Squash require a sunny site. They thrive best in light, deep, humus-rich soil. However, they do well in lumpy clay soil. All squash require young compost. Amend the soil with 1 to 1.5 t of young compost per 100 m2. Adding mineral phosphate encourages fruit set. Monthly fertigation with plant manure increases yield. The recommended pH for growing squash is between 6 and 6.5.

Squash Crop Rotation

Squash are grown at the start of the rotation, ideally after green manure .

Companion planting of squash

Squash should be grown to the east of the corn plot, which then acts as an annual windbreak and provides partial shade for the vines that creep through it. Squash also grows well alongside sunflowers, cucumbers, and melons. Avoid planting them with potatoes and tomatoes. Marjoram and basil are good friends with squash.
