The watering of the lychee

This plant, especially during flowering, fears excessive humidity; consequently, if the rains are frequent, irrigation must be done occasionally, when the soil is completely dry. However, prolonged drought must also be avoided, and the tree must be watered constantly during the driest periods. A factor that regulates the administration of water is, therefore, represented by the rains; even the age of the plant, however, must influence the irrigations, since the young specimens must be followed more carefully and supplied more often with water resources. Water stagnation must be avoided at any cost: in fact, they cause dangerous rot at the roots which soon lead to the deterioration of the entire tree.

Growing tips

The multiplication of Litchi generally occurs through techniques such as cutting and layering; usually we tend to avoid sowing, since with this method the development of the plant would be slow and the production would be very poor. The ideal soil is not very compact, deep and has excellent drainage: for this purpose, it is advisable to mix a little pumice stone with the soil. Pruning is aimed both at defining the shape of the tree in the first years of growth, and at removing diseased or dry branches; if fungal diseases occur, the affected parts must be removed immediately in order to prevent them from spreading. To improve the chemical and physical characteristics of the planting soil, annual mulching with bark or straw fragments is recommended.

How to fertilize the plant

Fertilization must take place approximately every three months, with ternary products based on potassium, nitrogen and phosphorus; however, minor elements such as boron, magnesium, manganese and zinc should not be overlooked. Alternatively, a natural fertilizer, such as manure or manure, can be used. It is appropriate to underline the importance of the three macroelements previously mentioned: potassium, in fact, is essential as it supports the production of ATP and the synthesis of proteins, nitrogen helps the growth of tissues, and phosphorus, finally, stimulates the metabolism and rooting. The fertilizer must balance these three elements in balance: a lack of them could be very dangerous for the health of the tree, causing general weakness and stunted growth.

Lychee: Exposure, pests and diseases

The ideal exposure is sunny and bright, with temperatures of around 25 ° C; the plant tolerates both heat and cold well, but it is essential that it is not hit by too intense winds. Furthermore, the Lychee can undergo infestations by aphids, which are recognized by their green or black color and by the perforations they cause in the foliage and buds: these insects, in fact, suck the sap of the affected tree. A suitable solution is nettle macerate, prepared with nettle leaves soaked in a basin of water. Furthermore, fungal diseases such as molds and rot can occur; if possible, it is recommended to eliminate the affected parts as soon as possible, using disinfected tools, and to perform two or three treatments based on fungicides.
