Description

'Clovis F1' cauliflower is a vigorous, very cold resistant variety that produces beautiful, round, uniform heads. The growth of this winter cauliflower is relatively slow (harvest 160 to 180 days after sowing). Sow from April to August for harvests from September to January.

Cauliflower (Brassica oleracea botrytris) is a popular vegetable belonging to the large Brassicaceae family (ex-Cole family). This biennial plant is grown as an annual for its edible flower head (meristem). It is thought to be native to the Island of Cyprus. The most common varieties display creamy white heads (or “curd”). However, more recently, different coloured cultivars have been introduced with orange, purple or green heads. Cauliflower has a mild, nutty taste. It is delicious eaten raw with dips, blended in velouté soups, or lightly steamed and added to gratins or quiches. It also goes very well with curry. From a nutritional point of view, it is very healthy: it is low in calories but very rich in vitamins, fibre and minerals. The orange varieties contain beta-carotene.

Cauliflower can be a rather tricky vegetable to grow. It requires deep, rich soil, and regular watering. It enjoys plenty of sun but not too much heat as this tends to make the florets taste more bitter. Better results are generally achieved in cooler, rainier climates. There are many varieties to choose from. By respecting the correct growing period, it is possible to harvest cauliflowers nearly all year round.

Harvesting: To harvest Cauliflower, simply cut off the central head with a sharp knife when it feels suitably compact and heavy.

Storage: Cauliflower does not keep very well. It is best to eat it quickly after harvesting, although it will keep for a few days in the refrigerator. It is also possible to freeze the florets after having blanched them in boiling salty water for a few minutes.

Good to know: For the past few years, swede midges (Contarinia nasturtii) have been causing considerable damage to brassica plants. We recommend protecting your crops with insect netting from mid-May to mid-July.

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.

Planting and care

Sowing:

The germination temperature of Chou-Fleur Clovis F1 is around 12°C and takes about 14 days.

It can be sown from April to August for a harvest from September to January.

You can sow directly in place or prepare seedlings that will then be planted in their final position in the garden.

Seedling preparation: at home or in a heated greenhouse, from late autumn to late spring, or in a cold greenhouse or nursery the rest of the year, sow the Cauliflower seeds at a depth of 1 cm in a tray filled with good seed compost. Lightly cover with compost or vermiculite. Cover with the transparent lid of the tray or plastic film until germination. Don't forget to keep the substrate moist but not waterlogged!

When the young plants appear strong enough to be handled, transplant them into pots and, for seedlings in a heated greenhouse, gradually acclimate them to cooler temperatures before transplanting them into the garden when there is no longer any risk of frost.

Direct sowing: In well-amended and finely worked soil, create furrows about 1 centimeter deep, spaced 60 cm apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out, keeping only one plant every 60 cm or so.

Cultivation:

Cauliflower is a demanding vegetable that requires well-fertilized soil rich in nitrogen and potassium. It is advisable to apply a generous amount of mature compost (about 3/4 kg per m2) in autumn, by scratching it into the soil to a depth of 5 cm, after having loosened the soil as you would for any vegetable crop. It is not very tolerant of soil pH, which should be between 5.6 and 6.5. In acidic soil, it will be necessary to gradually raise the pH by adding calcium in the form of Dolomite or Lime.

Cauliflower, like all cabbages, is quite susceptible to diseases such as Clubroot and pests (Cabbage White, Cabbage Fly, Flea Beetle, Cabbage Midge...), so it is very important, for this crop, to practice crop rotation.

It is beneficial to associate it with many vegetables such as tomato, lettuce... But avoid planting it near other Brassicas as well as zucchini, fennel, lamb's lettuce, leek, and strawberry.
