Tight cherry cousin, amarena is a fruit with an acid taste that lends itself well to both fresh consumption and the preparation of preserves and sweet and savory dishes. Its plant, the prunus cerasus or sour cherry, is very resistant and adapts easily to all soils. It does not require special care and is therefore one of the easiest fruit trees to grow. Moreover, it is a splendid ornamental plant, both in spring, when the branches are covered with delicate white flowers, and in summer with its juicy red fruits. To plant this tree it is sufficient to dig a hole in the ground and place organic fertilizer on the bottom, like manure or compost. If the soil is calcareous and poor in iron it is better to add a supplement to avoid chlorosis. Once the plant is inserted, the hole can be filled by covering the roots. It should be watered daily, but do not overdo it. Stagnant water that could cause root rot should be avoided. So, if the soil is too compact, you can replace part of it with sand to help drainage.
The black cherry tree does not need great care and grows rapidly. It adapts easily to different environments, withstanding hot and dry climates as well as fairly harsh winters. It can therefore be grown in every region. Pruning is also not particularly demanding. In the early years it has the function of giving the crown the right shape. The first year, at the beginning of spring, it is sufficient to check the ends of the branches to favor their growth. The second and third years must eliminate all the branches that grow inward and leave only those facing outwards. This creates a fan-shaped crown that allows the sun and air to reach all branches. In the following years it is advisable to eliminate also the branches that point straight upwards, as they only produce leaves and remove nourishment from the branches that bear fruit. Apart from these interventions, the plant must be pruned as little as possible, limiting it to thin out when it becomes too full.
The sour cherry can grow in any type of soil without difficulty. However, to promote the growth of sour cherries it is useful to intervene with organic fertilizers and nitrogen and iron supplements. In the first years of life, it is not necessary to fertilize the plant. After the first fruiting instead, which takes place between the third and fourth years, manure or compost can be used to nourish the soil. It must be used at the end of the fruit harvest, between June and July. An organic nitrogen-rich chemical can be added to the organic fertilizer, a substance the plant greatly needs. Furthermore, especially in the presence of calcareous soils, it is advisable to use an iron supplement. The lack of this element can in fact cause chlorosis, or the yellowing of the leaves, and the weakening of the health of amareno.
Amarena: Exposure and diseases
The black cherry tree loves the sun. It must therefore be positioned in a sunny and ventilated area, avoiding strong winds. It would also be better to avoid exposure to the north. Withstanding both the great heat and the winter frost without problems, it does not need to be planted in particularly protected areas. Despite being naturally resistant, the sour cherry is however subject to infestations of insects and fungi. To avoid these problems, it is possible to intervene in advance. First of all, in autumn, all the fallen leaves must be gathered, which could harbor insect larvae. You can then proceed with an anti-cryptogram action on the plant and on the ground, to eliminate any possible larva left. At the beginning of spring, on the other hand, specific products can be used to prevent the onset of mold. Finally, during flowering and fruiting, the plant must be checked. In this period in fact, the appearance of parasites could compromise the harvest. At the first signs it is appropriate to intervene to eliminate them.
