Chorisia speciosa

How to irrigate chorisia speciosa

Watering must be adjusted on the basis of the age of the specimen: if, in fact, the plant is young, it is necessary to water constantly, at least twice a week, especially during the summer season. On the contrary, if the tree is adult, the water supply can be thinned out, and during the wettest periods, rainfall may be sufficient. It is absolutely necessary to avoid water stagnation, one of the most common causes of weakness and rotting of the root system. The recommended irrigation method is by sprinkling or drip, which involves the use of special drippers to be placed under the tree: they emit thin jets of water, which can be directed on the surface of the soil or in depth, in the root area.

Growing tips

Chorisia speciosa multiplies through sowing; it is recommended to keep the seeds wrapped in a wet cloth for a day before planting. This plant can initially be grown in a container, filled with soil, peat and a little sand, and then transplanted into the garden with the utmost caution. The suggested soil is well drained, to avoid stagnation of water, deep and fertile; it, as a preliminary operation to the plant, must be worked and deprived of all weeds. Pruning must be carried out starting from the first year, carefully cutting off excessively protruding branches, dry ones and those affected by any fungi. For this important operation, it is necessary to use sharp, clean and disinfected shears.

Fertilizing the plant

This tree must be fertilized annually, if possible in autumn, in order to strengthen it in view of the winter cold; it is recommended to use a granular fertilizer based on potassium, nitrogen and phosphorus. These three elements are fundamental for the plant, and a lack of them can be really dangerous, as it causes a weakening and slowing of growth. Potassium is essential for protein synthesis, for the production of ATP and for increasing resistance to frost; nitrogen supports the development of tissues and guarantees an adequate presence of chlorophyll in the leaves; finally, phosphorus helps metabolism and rooting. In addition to these three macro elements, the fertilizer must also include micro elements such as magnesium, copper, calcium, iron and manganese.

Chorisia speciosa: Exposure, pests and diseases

The ideal exposure for Chorisia speciosa is bright, in full sun, sheltered from bad weather and excessive cold; this tree, in fact, is damaged by too low temperatures. On the other hand, it is quite resistant to parasites, although infestations of scale insects can sometimes occur. The latter cause widespread yellowing of the foliage, as well as attracting ants through the production of honeydew: an excellent remedy is the white mineral oil, which causes the suffocation of these phytophagous insects. The tree, moreover, could run into fungal diseases such as powdery mildew, which manifests itself as a sort of whitish mold and which causes a progressive deterioration of the affected specimen; one solution is represented by treatments with sulfur-based fungicides.
