Cabbage - Brassica oleracea var. happened

Generality

Brassica oleracea var. capitata is a vegetable grown in Europe for millennia; it seems to have been cultivated and consumed already in the times of the ancient Romans; there are three main groups, white cabbage, purple cabbage and savoy cabbage; it is the same plant, from each group there are dozens of cultivars available, different for ripening time, development season, shape and size of the cap. These are annual plants, which develop a dense flower head, consisting of large rounded leaves, the flower head is so narrow and compact that a large round "head" is formed in the center, the size of which varies from 10-15 cm in diameter up to to 70-80 cm of diameter in the giant varieties. The leaves of Brassica oleracea var. capitata are eaten raw or cooked, are used to prepare sauerkraut, cooking the leaves in water and vinegar, to be able to preserve them for a long time.


Cultivation

The specimens of Brassica oleracea var. capitata reach maturity in about 60-120 days from sowing; there are varieties with spring, autumn and summer sowing; generally the best development occurs in a cool climate, so in Italy young plants tend to be planted in the vegetable garden in autumn or late winter, for a winter or late spring harvest. Young plants can also be obtained from the seeds of the previous year's specimens: keeping a cabbage plant in the ground, this will produce thin erect stems that bear numerous small yellow flowers, followed by the seed pods. Since cabbage has been cultivated for millennia in our gardens we always plant cultivars, for this reason the plants obtained from seed are not always identical to the mother plant; for this reason we prefer to buy the young plants already developed, or even the seeds, already selected.

Cultivation techniques

They are grown in soft soil, enriched with mature manure and well worked in depth; the young plants are arranged in rows at least 20-35 cm apart from each other.

They need full sun and love a cool and well-drained soil; they do not tolerate drought, so it is necessary to intervene with watering when the soil has been dry for a few days: winter cultivation generally does not require watering, as the climate usually provides the right rainfall. It is good to check that the chosen substrate does not allow the formation of water stagnations which could easily lead to the onset of rot.


Cabbage - Brassica oleracea var. capitata: Possible Diseases

Brassica generally fears the attack of snails, especially young plants, and cabbage butterflies, whose larvae quickly devour the foliage; in general the winter cultivation also obviates this problem, since the inclement climate does not favor the development of parasites; if instead spring cabbages are grown, it is advisable to cover them with non-woven fabric or a fine mesh net, so as to mechanically prevent insects from accessing the foliage of our plants. In the event of an infestation already in progress, however, we promptly eliminate the insects that could destroy the entire crop.
