This plant, if cultivated in pots, needs constant watering, in particular during the flowering period; in any case, water stagnations must be avoided, which frequently cause root rot 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, irrigations must be regulated on the basis of rainfall; consequently, a greater quantity of water resources must be administered during the periods of drought, while in winter, and in particular if the rains are frequent, it is essential to limit the watering. It should also be remembered that younger specimens have a higher water requirement than adult ones. You should always remember to check carefully that no water stagnations form, as they could cause dangerous root rot in a short time.
The multiplication of this elegant shrub generally occurs by cutting; the ideal soil for the rincospermo it is light, fertile, well drained, but it is recommended to avoid soils with acid pH. If you choose to cultivate in pots, it is essential that the latter is quite large, with a diameter of at least 50 centimeters, and that the repotting is carried out in spring. In the garden, immediately after planting, a mulching of the soil is appropriate to make it softer and more aerated and to improve its physical-chemical characteristics. This plant can be used for the construction of hedges: in this case it is recommended to leave about one meter of space between one specimen and another. Pruning should only be done to eliminate any dry or diseased branches.
