When and how much to irrigate
The species and varieties belonging to the genus called Albizia are around 50 and can be grown in pots or in the open ground. Young plants need constant attention, especially during the delicate phase of rooting. In fact, a very important aspect is the water supply to be supplied on a regular basis, starting from the summer season. If this type of plants grows in areas characterized by hot and sultry summers, the quantity of water dispensed must be greater, in order to always achieve luxuriant growth. The Albizia specimens, already adult, are quite autonomous and need irrigation only in dry periods. In autumn the waterings are gradually reduced and in winter they are completely suspended, until the warm weather arrives.
How to take care of it
The plants belonging to the genus Albizia are rustic and are able to adapt without too many difficulties to various environmental contexts. In fact, they withstand the cold and temperatures far below zero, they resist the sultry heat and are not affected by saltiness. If they are grown in pots, they need large storage compartments, since they do not like the decanting carried out too frequently. The soil that the Albizia species prefer is fertile and well drained, the ideal is to choose a substratum composed of slightly acid soil mixed with a part of coarse sand, to ensure the drainage of irrigation. Pruning is necessary at the end of winter, to maintain the shape of the foliage and eliminate the dry and damaged branches from the cold season.
When and how to fertilize
The genus of vegetables called Albizia must be fertilized during the whole period of flowering. In fact, it is important to support these plants by providing the main nutrients needed for flower production. The best time to start administering a good liquid organic fertilizer is in late spring. The solution is diluted directly in the water intended for irrigation and the procedure is repeated approximately every 20 days. Alternatively, you can opt for a slow release granular fertilizer to spread on the ground. Furthermore, it is advisable to know, to choose the most suitable specific product, that this type of plant does not like fertilizers with high levels of nitrogen. Once the flowering is over, the administrations are suspended until the following spring.
The Albizia: Exposure, diseases and remedies
The shrubs and trees of Albizia prefer sunny and bright exposures, if they are cultivated in the northern regions. On the contrary, in the southern areas it is advisable to arrange the specimens towards the east, in such a way as to receive the correct amount of light and remaining sheltered from the sun of the hottest hours. The main enemy of Albizia plants is a phytophagous insect known as the psylla. Infestations are dangerous and seriously damage the entire structure of the plant. The prevention and monitoring of individual plants is important, moreover, it is advisable to contact specialized personnel to face the parasitic attack. In general, the use of potassium salts is recommended for larvae whereas adult insects should be treated with rotenone.
