Horse chestnut irrigation
The horse chestnut, also known as the Indian chestnut, is widespread in Europe with a decorative function. It belongs to the sapindaceae family and is quite resistant to low temperatures and to all types of soil. Instead it suffers from pollution and excessive salinity of the soil. It does not require much effort from the point of view of irrigation because in places where it rains from time to time it is not necessary to provide for a further supply of water. Instead, it is necessary to irrigate it in the event of drought or insufficient rainfall. As with all other trees, it is necessary to take preventive action with respect to the possible problems that may arise. The first thing to do is to take care of its correct location, which must take place where there is enough space, and away from smog. It is also necessary to take care of the cleaning around the horse chestnut to avoid the nesting of parasites.
How to cultivate and care for the horse chestnut tree
Since the horse chestnut fears pollution, the first thing to do is to choose a location that will repair it from the smog. If, for example, you have a garden, it is preferable to place the tree so that it faces a pedestrian avenue or anyway with little traffic. It should also be borne in mind that the horse chestnut can reach a height of 25 meters and its foliage can expand up to 10 meters in diameter, therefore it will be necessary to leave a space around the tree adequate for its maximum potential expansion. Its seeds must be planted in the autumn season. The horse chestnut plantation can take place in the nursery. In this case it will be possible to proceed with the planting after two or three years. It reacts badly to pruning and is therefore best avoided. Its fruits are very similar to chestnuts, but we must remember that they are not edible because they are excessively bitter.
How and when to fertilize
The fertilization of the land, necessary to fertilize the environment in which the hippocastate is allocated (or intends to allocate), is very important. It is vital that it occurs before planting and it is very useful that it is repeated annually especially in the first years of the tree's life. Since the planting must take place in the autumn season, fertilization must be carried out in good time. The horse chestnut fears the saline soils which must be used to desalinize the soil during fertilization. However, if the ground turns out to be inadequate, it is suggested to plant the horse chestnut tree elsewhere or to place a different tree on the same land, to prevent the cultivation from being successful. Among the types of fertilizer to be chosen we recommend the organic type.
Horse Chestnut: Exposure, diseases and possible remedies
The hypocastathine needs a lot of light and therefore must be exposed to the sun. This allows the tree to feel good and be used for shade. In recent years, given the excess of smog, horse-chestnuts located in urban centers are showing problems with reddening of the leaves especially at the end of the summer season. This problem, which occurs mainly at the edges of the leaves, should not be confused with their mottling which instead is symptomatic of the presence of guignardia aesculi. In this case it is necessary to intervene with fungicides. Another dangerous enemy of the horse-chestnut tree is the cameraria ohridella, a miner moth, which infests the tree starting from the lower part of the foliage. In this case it is necessary to intervene with appropriate pesticides.
