When and how much to irrigate
Chestnut is a plant species of European origin. The Italian woods are particularly rich in these trees that can reach remarkable heights (up to 25 meters). In fact, the best climatic conditions for cultivation are those of the Mediterranean areas. Chestnut can easily withstand low temperatures as well as high temperatures, as long as they do not last too long. Precisely by virtue of this climatic adaptation, it is not necessary to intervene with regular irrigation in adult specimens. However, in periods of greater heat and drought it is good to support the plant with irrigation, at least until the autumn rainy season arrives. Young specimens, on the other hand, need regular irrigation every three weeks.
How to cultivate and care for it
The consistent size of the chestnut makes its cultivation in the garden almost difficult. However, this does not mean that this tree can also be cultivated in flower beds. When the cultivation is done in a vase, quite tall and resistant structures are chosen, around 150 cm, since these plants are predisposed to assume large dimensions. As for pruning, chestnut does not require a very invasive intervention. In the first four years of life, only dry branches and damaged structures must be cut, which could compromise the health of the plant. After the fourth year, we simply intervene by thinning out the foliage and eliminating the parts that hinder the filtration of the sun which must affect all the surfaces of the shrub.
When and how much to fertilize
Fertilization is one of the fundamental phases of the chestnut cultivation process, which certainly influences the growth of this plant. The first thing necessary to do is an analysis of the composition of the soil in which to cultivate, to evaluate its acidity, pH and all the other main chemical-physical characteristics that could interfere with good cultivation. When preparing the soil, this is enriched with organic compound. This will represent the plant's nutrition for the first few years to follow. Furthermore, it is good practice to fertilize with controlled amounts of natural fertilizer (the so-called animal manure) in alternate years. It is also possible to carry out fertilization through the use of chemical fertilizers, even if this practice is used more exclusively in plantations of chestnut trees only.
Chestnut: Possible diseases
Like all trees, the chestnut is also subject to the attack of parasites and pathogens that can seriously affect the health and integrity of the shrub. In order to avoid this, it is necessary to intervene during pruning with instruments (both tools and operator's gloves) carefully washed and sterilized. It is also important to keep the base of the trunk adequately clean, since this could be a source of parasitic contamination. Furthermore, specific substances must be used to facilitate healing at the level of pruning to prevent infiltration of pathogens. Among the most characterized types of chestnut tree disease, the one called bark cancer that arises following the attack of pathogens that manage to infiltrate pruning wounds is certainly to be remembered.
