Description

The 'Walcheren' Winter 5 Cauliflower (in Latin, Brassica oleracea botrytis) is a variety of excellent quality, very hardy, that produces beautiful compact and white heads. This cauliflower is sown from May to June for a harvest from September to October.

With a beautiful immaculate white 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 the Cabbage of Cyprus, the Cauliflower is a biennial vegetable plant originally from China.

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

There are many varieties of Cauliflowers, each corresponding to a distinct growing period that should be respected. Thus, by carefully choosing your seeds, you can have this vegetable all year round.

The Cauliflower is a demanding vegetable; it requires excellent basic fertilisation and regular moisture.

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

Storage: Cauliflower does not keep very well. It is preferable 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 little trick: The main enemy of cabbage, the Cabbage White (Pieris brassicae), is a pretty creamy white butterfly with small black spots that wakes up in 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 arches. These nets are easy to install and reusable to protect, for example, your carrot and leek crops.

Planting and care

Sowing:

The germination temperature of  'Walcheren Winter' Cauliflower is around 12° and takes about 14 days.

It is sown from May to June for a harvest in September to October.

You can either directly sow it in place 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 for the rest of the year, sow the cauliflower seeds at a depth of 1 cm (0in) 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. Remember to keep the substrate moist but not soggy!

When the young plants appear strong enough to handle, transplant them into pots and, for seedlings in heated greenhouses, gradually acclimatise 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 one centimetre deep, spaced 60 cm (24in) apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well established, thin them out, leaving one plant every 60 cm (24in) or so.

 

Cultivation:

Cauliflower is a demanding vegetable that requires well-rotted, nitrogen- 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 loosening 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 is necessary to gradually raise the pH by applying calcium in the form of Dolomite or Lime.

Like all cabbage plants, Cauliflower is quite susceptible to diseases such as Clubroot and pests (Cabbage White Butterfly, Cabbage Fly, Flea Beetle, Onion Fly...), so crop rotation is very important for this crop.

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