Albizia

How to irrigate albizia

This elegant plant can be grown both in open ground and in pots. In the first case, irrigations must be regulated on the basis of rainfall: that is, they must be intensified during the summer season, particularly if there are periods of prolonged drought, and limited during the winter, especially if the rains are frequent. If the cultivation takes place in pots, however, it is necessary to water constantly and ensure that the soil does not remain dry for a long time. For irrigation in the garden, the sprinkling method is suggested, which allows you to manage water resources in a controlled manner and to wet the soil directly, avoiding foliage. It is extremely important not to run into water stagnation, which is dangerous as it causes root rot.

Growing tips


Albizia adapts quite easily to various types of soil, even if it prefers slightly acidic, soft and, above all, well-drained soils. The multiplication takes place through sowing, to be carried out in spring, or by summer cutting; in both cases it is necessary to carry out the implantation in a special container, to be constantly monitored, and then transplant the still very young specimen in a larger pot or in the garden. Pruning must take place at the end of winter, and is aimed at eliminating dry branches, damaged by the cold and intense winds; it is essential to use specially disinfected and sharpened tools, such as shears. In parks and gardens, plant development can be helped by periodically mulching the soil.

How to fertilize


Fertilization can be carried out with a slow-release granular product, annually, at the end of the winter season, or with a liquid fertilizer to be administered once a month, during the flowering period, together with irrigation water. The important thing is to provide the plant with the right amount of nitrogen, potassium and phosphorus, the three macro elements, plus some equally essential micro elements such as magnesium and manganese. The three major elements play a fundamental role: nitrogen, in fact, supports the development of tissues, potassium helps protein synthesis and the absorption of sugars and, finally, phosphorus promotes metabolism and strengthening of the roots. However, it is necessary to ensure that nitrogen is never too abundant, as it would cause a weakening of the

Albizia: Exposure, parasites and diseases


Albizia develops correctly both in full sun and in partial shade; the exposure, however, must take place in environments protected from bad weather. Low temperatures are tolerated, as long as the cold is not excessive: otherwise, in fact, the cultivated specimen could even die. A very annoying parasite is the psylla, an insect that feeds on the sap of the plant causing perforations to the buds and leaves; the latter undergo a progressive yellowing, until they dry out completely. The most effective remedy consists of specific pyrethrum-based insecticides. In cases of overabundant humidity, fungal diseases such as rot and mold may also occur, causing a general deterioration of the plant and which can be countered with copper or sulfur-based fungicides.
