Description

The 'Clapton F1' Cauliflower (in Latin, Brassica oleracea botrytis) is a beautiful variety with good taste quality, specially selected for its resistance to clubroot. The sowing of this Cauliflower is to be spread from April to June for a harvest from August to November.

With a pure white colour and even, in recent years, joyfully yellow, orange or purple, the Cauliflower is a flowering vegetable whose fleshy meristem is consumed. It belongs to the large family of Brassicaceae (formerly Cruciferae) and bears the Latin name Brassica oleracea botrytis. Sometimes called Cyprus Cabbage, the Cauliflower is a biennial vegetable plant originally from China.

Consumed for the first time in Germany only 300 years ago, this vegetable has earned a place of honour in our kitchens because it lends itself to many preparations. It can be consumed raw in salads or cooked, plain, in a gratin with béchamel sauce or accompanied by a curry sauce that complements its flavour very well. It is a low-calorie vegetable and rich in vitamin C.

There are many varieties of Cauliflowers, each with a distinct growing period that must be respected. You can have this vegetable all year round by carefully choosing your seeds.

Cauliflower is a demanding vegetable requiring excellent basal fertilisation and regular moisture.

NB: This variety is labelled F1 for "F1 hybrid" because it results from the cross-breeding of carefully selected parents to combine their qualities. This results in a variety that can be exceptionally flavorful and early while resistant to certain diseases. Sometimes criticised or wrongly associated with GMOs, F1 hybrid seeds are attractive for their uniformity and resistance. Still, unfortunately, their qualities do not pass on to subsequent generations: it will, therefore, not be possible to recover the seeds for later sowing.

Harvest: The Cauliflower is harvested when its head is compacted by cutting it at ground level.

Storage: Cauliflower does not keep very well. It is best to consume it quickly after harvesting. It can be kept for a few days in the refrigerator. You can also freeze it after blanching it for 3 minutes in salted boiling water.


The gardener's tip: The main enemy of cabbage, the Cabbage White Butterfly (Pieris brassicae) is a pretty cream-white butterfly with small black spots that awakens from April-May to wreak havoc all summer by devouring its leaves. While spraying a solution based on Bacillus Thuringiensis is an acceptable curative measure, we prefer, at our place, to opt for prevention by installing an insect-proof net tightly on market garden hoops. These nets are easy to set up and reusable to protect, for example, your carrot and leek crops.

Planting and care

Sowing:

The germination temperature of the 'Clapton F1' Hybrid Cauliflower is around 12° and takes about 14 days.

It should be sown from April to June for a harvest from August to November.

You can either sow directly in the ground or prepare seedlings that will later be planted in their final position in the garden.

Preparing Seedlings: At home or in a heated greenhouse, from late autumn to late spring, or in a cold greenhouse or propagator the rest of the year, sow the cauliflower seeds to a depth of 1 cm (0in) in a tray filled with good seed compost. Cover lightly with compost or vermiculite. Cover with the transparent lid of the tray or with plastic film until germination. Don't forget to keep the substrate moist but not waterlogged!

When the young plants appear strong enough to handle, transplant them into pots and, for seedlings in a heated greenhouse, gradually acclimatize 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, make furrows about 1 centimeter (0 inches) deep, spaced 60 cm (24in) apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out, leaving one plant every 60 cm (24in) or so.

Cultivation:

Cauliflower is a demanding vegetable that requires well-rotted, nitrogen-rich and potassium-rich soil. It is advisable to apply a generous amount of mature compost (about 3/4 kg per m2), by digging it in to a depth of 5 cm (2in), preferably in autumn, after thoroughly loosening the soil, as is the case for all vegetable crops. 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 Butterfly, Cabbage Root Fly, Flea Beetle, Leaf Miner...), so it is very important, for this crop, to practice crop rotation.

It is beneficial to associate cauliflower with many vegetables such as tomatoes, lettuce... But avoid planting it near other Brassicas as well as zucchini, fennel, lamb's lettuce, leeks and strawberries.
