Sour cherries

When to irrigate

The black cherry tree (also called bitter cherry) is a very common plant in the Asian continent but also widespread in the Mediterranean areas. For its growth it prefers mountainous or hilly terrain and can reach great heights. Its flowers are white and composed of five petals, while its fruits (precisely the black cherries) are red and are highly appreciated for their sour taste. The black cherry plant does not require particular attention during the irrigation phase. In fact, it is satisfied with natural rainfall, while in periods of severe drought it may be necessary to intervene by the grower. It is advisable to plant the black cherry tree in a cooler and more absorbent soil, capable of retaining and better distributing the water.

Proper cultivation


The sour cherry tree is a very hardy plant. It can grow even in very harsh climatic conditions, even if it prefers a continuous exposure to sunlight in a ventilated area. For its development, the plant does not require particular types of land, in fact it can also grow in the wild. Various pruning operations can be carried out to allow the plant to grow healthily. For example, you can shorten some bearing branches to prevent too excessive fruiting or cut off the main branches to contain the size of the plant. These pruning operations can have to be done about every three years. The bitter cherry tree is very early, in fact around the first year it is already possible to see the different buds that bloom,

How to fertilize


The black cherry plant is a self-sufficient tree that therefore manages to independently provide for its own development. However, to obtain healthier growth and a quantitatively and qualitatively better production it is advisable to treat the plant with special fertilizers at certain times of the year. The optimal period for fertilization is around the end of the summer season, when the plant is still in its period of vegetative recovery. It is also advisable to make some additions with organic fertilizers during the spring, to ensure the plant absorbs all the nutrients necessary for its proper development. This addition of organic fertilizer should possibly be done after the flowering of the black cherry tree. Fertilizers based on potassium, phosphorus and calcium are recommended,

Sour cherries: Diseases and remedies


Being a wild plant, the sour cherry tree often develops independently the ability to protect itself from the attack of parasites, fungi or diseases of various kinds. The greatest danger to the black cherry plant is the poor nutrition of the soil in which it grows or the lack of necessary nutrients. The growth in an inadequate soil can in fact be the cause of a premature decay of the plant, cause of yellowing and fall of the leaves and poor fruit production. This problem can be overcome with proper cultivation, irrigation, fertilization and pruning. Too cold and humid climates, on the other hand, can be the cause of the proliferation of mold, which mainly attacks the leaves and fruits. Protecting the plant from these climatic conditions is the best solution to avoid such problems.
