Radicchio is a vegetable that gives its best in December, at the lowest temperatures which accentuate its characteristic flavor. The green leaf radicchio is characterized by the high content of chlorophyll and iron: it is a valuable aid for those who need to regulate and balance intestinal functions, by virtue of the richness of fibers that characterizes them; not to be underestimated, also, is the bitter taste, which translates into an important contribution to a correct digestive activity. As for the red leaf radicchio, however, it has a high content of anthocyanins, which are nothing more than red pigments that help protect cells and the heart from aging. Radicchio is a plant particularly suitable for individuals suffering from high blood pressure, by virtue of their diuretic action favored by potassium, which contributes to the drainage of cells, or osteoporosis: thanks to the moderate calcium content. This vegetable, on the other hand, is also recommended for women willing to get pregnant, as they represent an excellent source of folic acid, while it does not create problems for diabetic subjects, since the sugar present in it, inulin, is absolutely harmless. Chosen in numerous slimming diets for its ability to satiate without making you fat (for a pound it provides only thirteen calories), even more if consumed raw, the radicchio is characterized by a full-bodied consistency that fills the stomach with taste.
Let's see, therefore, how to proceed for the cultivation of this type of vegetable. It should be noted, first of all, that the most suitable soil is a fresh soil, sufficiently drained and well structured, which must be worked at least twenty centimeters deep (but not more than forty) in order to be then chopped up and then leveled with rakes. and hoeing. The radicchi, as mentioned, can be grown at any time of the year, even in the winter months, as it is able to withstand temperatures well above zero: attention must be paid only to early autumn frosts, which occur immediately after sowing. The risk in cultivation, in fact, is that they induce the plant to produce flowers, with consequences making the production of leaves vain. If you want to apply a crop rotation, radicchio happens without problems to cabbage, strawberries, onions, carrots, celery, potatoes, spinach and beans. Instead, care must be taken not to sow it for two consecutive years in the same flower bed, as well as after vegetables belonging to the same family: for example artichokes, and of course salads.
