ORNAMENTAL CABBAGE

ORNAMENTAL CABBAGE

Cabbages belong to the botanical family of the Brassicaceae which includes a wide number of very interesting species used for human consumption and cultivated since ancient times. According to some experts, their use goes back 6000 years. Recently, cabbage has been planted in gardens as ornamental plants thanks to their foliar ability to turn into bright hues and to their resistance to cold, frosty weather. These plants are sold when they have reached their definitive size and colour. In general, cabbages require moist and deep soil but they also adapt to other conditions. If potted, a good mix could be 70% organic compost and 30% inert sand or expanded clay. Due to their size, it is advisable to use vases or containers that are big enough. Ornamental cabbages have an excellent resistance to cold (some varieties survive even at -10° C). They are cultivated in autumn and in winter and can be planted in gardens or on balconies in late summer in order to enjoy their colourful leaves up to spring when, with the rise in temperature, they produce flowers which are not at all ornamental. The plants must be placed in full sun or in part-shade. If grown in gardens, avoid wet soils. Feed once a month with soluble ternary fertilizers that contain plenty of potassium. Water according to the weather: in winter too much watering could reduce resistance to cold. In cold weather, cabbages are not attacked by insects, but may have problems with the following fungi: mildew and gray mould (Botrytis). To prevent the latter disease, it is sufficient to spray the plants with copper. If the plants are already infected, use downy mildew and anti-botrytic treatments.
