When to irrigate

Carrubo is the common name of Ceratonia Siliqua, an evergreen tree of the Leguminosae family. It is a very beautiful, elegant and decidedly ornamental specimen. Originally from Arabia, it grows spontaneously in the Mediterranean region, especially in the coastal and sublittoral belt. It therefore prefers very hot, almost steppe climates. The Carob plant has a large trunk, not very tall, and a large, luxuriant, somewhat dense crown. The Carob tree has a remarkable resistance to drought: in fact it can withstand prolonged periods without water. As a xerophytic species it lives without problems even in climatic zones with 250-500 mm of annual rainfall. However, it is necessary to pay more attention to young plants during their first 2-3 years of life: during the summer months a sliding irrigation. Once the specimens are adults, the water supplies become more spaced apart.

The cultivation techniques

The Carob has a robust root system that anchors it in any type of soil. The leaves, leathery and compound, are arranged alternately. The individual leaves are rounded, shiny and a beautiful dark green. The small flowers gather in racemic inflorescences. The fruits are legumes, the so-called carob beans, 10 to 25 cm long: they contain oval, reddish-brown seeds, called carats, which in ancient times were used to weigh gold and precious stones. The carob is an object of specialized cultivation (carob grove) in all the countries of the Mediterranean belt, including Italy. This plant grows well even in very arid and rocky places, not only in the plains but also on hills up to 600 meters; climates must always be very hot and dry. It is a very rustic plant, which requires little care;

Fertilization techniques

In the areas near the coast, the Carob tree is cultivated as an ornamental plant: in fact the specimens are distinguished by the beautiful shape of the tree, for the dense and shiny foliage, which projects a very large shadow, and for the decorative lomenti both in the green state. than when they have reached maturity. As far as fertilization is concerned, this species requires an administration equal to 300-400 kilos of mature organic matter for every 1000 square meters of carob grove at the time of planting the specimens. In most cases, manure is used because it is a very balanced and complete product. Subsequently, the Carob receives 40-50 kilos of manure per specimen every 2-3 years: it is necessary to slightly break the surface of the soil and spread the fertilizer near the roots. As an alternative, in autumn,

Carob: Possible diseases and parasites

The Carob tree needs exposure in full sun to be able to develop at its best. From the point of view of temperature, this plant must live in warm climates, as it is not affected by high external temperatures. On the contrary, the species can suffer damage if during the winter season the temperature is below 5 ° C: in this case it is necessary to develop some precautions, for example protecting the specimens with plastic sheets. Even though it is a robust tree, the carob is sensitive to the action of fungal diseases and parasites. In the first case, it is necessary to pay great attention to the drainage of the soil, in order to avoid dangerous water stagnation. As for the problems related to insect infestations, specific products must be used to eradicate them.
