This plant, if grown in pots, needs constant watering, particularly during the flowering period; in any case, it is necessary to avoid water stagnation, which frequently cause rottenness to the roots and very annoying fungal diseases. It is suggested to use demineralized water or, in any case, low in limestone. If instead the rincospermo it is grown in the garden, irrigation must be regulated on the basis of rainfall; consequently, a greater quantity of water resources must be administered during periods of drought, while in winter, and in particular if the rains are frequent, it is essential to limit watering. It should also be remembered that younger specimens have a higher water requirement than adult ones. It is always necessary to remember to carefully check that no water stagnations form, as they could cause dangerous root rot in a short time.

Growing tips

The multiplication of this elegant shrub generally occurs by cutting; the ideal soil for rincospermo it is light, fertile, well drained, but it is recommended to avoid soils with acid pH. If you choose to grow in pots, it is essential that the latter is quite large, with a diameter of at least 50 centimeters, and that repotting is done in spring. In the garden, immediately after planting, it is advisable to mulch the soil to make it softer and more aerated and to improve its physico-chemical characteristics. This plant can be used for the construction of hedges: in this case it is recommended to leave, between one specimen and another, about one meter of space. Pruning should only be done to eliminate any dry or diseased branches.

How to fertilize

False jasmine needs to be fertilized twice a year, in early summer and during the fall season. A slow release fertilizer specific for flowering plants is recommended; the product in question must properly balance the three essential macro-elements for the shrub, namely potassium, nitrogen and phosphorus. Their deficiency would have completely negative effects on the specimen: it would cause slow growth and could cause leaf chlorosis. The fertilization carried out in autumn should bring less nitrogen than in spring, so as not to stimulate an excessive development of the vegetative parts in view of the winter cold. If possible, the fertilizer should also include equally important microelements such as magnesium, manganese and iron.

Rincospermo: Exposure, parasites and diseases

The rincospermo is able to tolerate both heat and cold, as long as they are not excessive. In any case, a sunny exposure is suggested; the plant also grows in partial shade, but in this case its flowering will be less luxuriant. Among the most frequent parasites for this shrub we must mention the cochineal, which is recognized for the protective coating with which it tends to cover itself and which can be eradicated with white mineral oil. Also dangerous is the red spider, responsible for the formation of necrotic areas and which can be counteracted with garlic products. Among the fungal diseases caused by overabundant humidity, however, it is necessary to remember the fumaggine; it manifests itself as a sort of dark mold and causes a general deterioration of the shrub. To combat it, fungicidal products are needed.
