Description

The 'Premium Crop F1' Broccoli Cabbage is a fast-growing variety that tolerates heat well. Sow from February to April under cover and from April to June in open ground for a harvest 55 days later.

Offering beautiful firm bouquets, mostly green but sometimes purplish or white, Broccoli Cabbage, commonly known as Broccoli, is a vegetable whose flowers are consumed just before they bloom. It belongs to the large family of Brassicaceae (formerly Cruciferae) and bears the Latin name Brassica oleracea italica.

Although introduced to France by Catherine de Medici under the name Italian Asparagus, Broccoli has only been extensively cultivated since the 1980s.

Originally from southern Italy, this cabbage, with its mild flavour, is now highly appreciated as it lends itself to many preparations. It is consumed quickly, steamed and then prepared in various ways: sautéed, gratin, quiche, mashed, soup... It is a low-calorie vegetable and rich in vitamin C.

Like almost all cabbages (Brussels sprouts being the exception), Broccoli Cabbage is a demanding vegetable, requiring excellent base 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 flavourful and/or early while resistant to certain diseases. Sometimes criticised or wrongly associated with GMOs, F1 hybrid seeds are interesting both for their uniformity and resistance, but unfortunately, their qualities do not pass on to subsequent generations: it will, therefore, not be possible to recover the seeds for later sowing.

Harvest: Broccoli is harvested by cutting with a knife in two stages: first, the terminal bouquet is harvested, then the lateral bouquets.

Storage: Broccoli Cabbage 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: In recent years, the Cabbage Gall Midge (Contarinia nasturtii), a small winged piercing and sucking fly, has been wreaking havoc on Broccoli Cabbages in certain regions. We recommend opting for prevention by installing insect-proof netting tightly on market garden arches throughout the flight period, from mid-May to mid-July. 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 'Premium Crop F1' Broccoli Cabbage is around 15°C (59°F) and takes about 14 days.

It can be sown from February to April under cover and from April to June in open ground for a harvest 55 days later.

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

Seedling preparation: at home or in a heated shelter from late autumn to the end of spring or in a cold greenhouse for the rest of the year, sow the Broccoli Cabbage seeds at a depth of 1 cm (0in) in good seed compost. Lightly cover with compost or vermiculite. Remember to keep the substrate moist but not soggy!

When the young plants appear strong enough to handle, transplant them into pots and, for sowing under heated shelter, gradually acclimatise them to cooler temperatures before transplanting them into the garden when there is no longer any risk of frost.

Direct sowing: In suitably amended and finely worked soil, make furrows about one centimetre deep, spaced 50 to 60 cm (20 to 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 only one plant every 50 cm (20ino.

Cultivation:

Broccoli Cabbage 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 scratching it to a depth of 5 cm (2in), preferably in autumn, after having loosened the soil, as is the case with 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.

Broccoli Cabbage, like all cabbages, is quite susceptible to diseases such as Clubroot and pests (Cabbage White Butterfly, Cabbage Fly, Flea Beetle, Cabbage Midge...), so this crop needs to pay attention to crop rotation.

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