Description

The Spiridon F1 Broccoli Cabbage is a hardy and late variety that produces beautiful heads weighing approximately 450g. Its open habit gives it good disease resistance. Sow in May for harvest in October and November.

Offering pretty firm bouquets, mostly green but sometimes purplish or white, the 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 cultivated on a large scale in France since the 1980s.

Originally from southern Italy, this cabbage, with its mild flavor, is now highly appreciated as it lends itself to many preparations. It is quickly steamed and then prepared in various ways: quickly 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 that requires excellent fertilization and regular moisture.

NB: This variety is marked F1 for "hybrid F1" as it is a variety resulting from the cross-breeding of carefully selected parents to combine their qualities. This results in a variety that can be particularly flavorful and/or early while also being resistant to certain diseases. Sometimes criticized or wrongly associated with GMOs, F1 hybrid seeds are interesting both for their uniformity and their resistance, but unfortunately, their qualities do not pass on to the next 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 and then the lateral bouquets.

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


The gardener's tip: In recent years, the Cabbage Midge (Contarinia nasturtii), a small winged piercing and sucking fly, has been causing havoc on Broccoli Cabbages in certain regions such as Brittany. We recommend prevention by installing an insect-proof cover, tightly secured on market garden hoops, throughout the flight period, from mid-May to mid-July. These covers are easy to put in place and reusable to protect, for example, your carrot and leek crops.

Planting and care

Sowing:

The germination temperature of the Spiridon F1 Broccoli Cabbage is around 15° and takes about 14 days.

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

You can either sow directly 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 shelter, from late autumn to late spring, or in a cold greenhouse or nursery 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 waterlogged!

When the young plants appear strong enough to be handled, transplant them into buckets and, for sowing in heated shelters, gradually acclimatize them to cooler temperatures before transplanting them to the garden when there is no longer any risk of frost.

Direct sowing: In properly amended and finely worked soil, create furrows about one centimeter 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 60 cm (24in) or so.

 

Cultivation:

Broccoli Cabbage is a demanding vegetable that requires well-manured soil, rich in nitrogen and potassium. It is advisable to make a generous compost application (about 3/4 kg per m2), by raking it in to a depth of 5 cm (2in), preferably in autumn, after loosening the soil, as is necessary 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.

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

It is beneficially associated 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.
