Description

The Broccoli 'Marcus F1' is a vigorous variety that produces large, fine-grained heads that are easy to harvest. This Broccoli is known for its reliability and disease resistance. It can be sown from March to late July for a harvest from August to late November.

Offering firm and compact florets, usually green but sometimes purple or white, the Broccoli, 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 has 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 since the 1980s.

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

Like almost all cabbages (Brussels sprouts being the exception), Broccoli is a demanding vegetable, requiring excellent base fertilisation and regular moisture.

Note: This variety is labelled F1 for "F1 hybrid" because it is derived from the cross-breeding of carefully selected parents to combine their qualities. This results in a variety that can be exceptionally flavourful and early-maturing while also being 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 save the seeds for future sowing.

Harvest: Broccoli is harvested by cutting with a knife in two stages: first, the central head is harvested, then the lateral heads.

Storage: Broccoli does not keep very well. It is best to consume it quickly after harvesting. It can be refrigerated for a few days. It can also be frozen after blanching for 3 minutes in salted boiling water.


Handy gardening tip: In recent years, the Cabbage Midge (Contarinia nasturtii), a small winged fly that stings and sucks, has been causing havoc on Broccoli in certain regions. We recommend preventive measures by installing insect-proof nets on market garden hoops during the entire 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 the Broccoli 'Marcus F1' is around 15° and takes about 14 days.

It is sown from March to late July for a harvest from August to late November.

You can either sow directly in place or prepare young plants to be planted in the garden in their final position.

Preparing young plants: at home or in a heated shelter from late autumn to late spring or in a cold greenhouse for the rest of the year, sow the Neck Cabbage seeds to a depth of 1 cm (0in) in good sowing compost. Lightly cover with compost or vermiculite. 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 sowing in heated shelters, gradually acclimatise them to cooler temperatures before transplanting them to 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, keeping only one plant every 60 cm (24in).

 

Cultivation :

Broccoli is a demanding vegetable that requires well-rotted, nitrogen-rich and potassium-rich soil. It is advisable to make a generous compost addition (about 3/4 kg per m2) by scratching the soil 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 will be necessary to gradually raise the pH by adding calcium in the form of Dolomite or Lime.

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

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