Solanum capsicastrum


Solanum capsicastrum is a plant originating from Brazil with a shrub with a height and diameter of about 30 - 50 cm; the solanum is an evergreen shrub usually cultivated as an annual with a woody and rather flexible stem. The leaves are lanceolate of a dark green shade. The flowers, on the other hand, are star-shaped white, with a width of 1 - 1.5 cm; the flowering period of the plant is June-July. At the beginning of winter the plant also produces its fruits. These are berries, shiny, first dark green, mottled that become yellow and then scarlet with maturation. Of this plant there are different cultivars among which we mention the capsicastrum, wendlandii and the pseudocapsicum.


The ideal exposure for the cultivation of solanum capsicastrum must be in the sun. They are plants that particularly love light and therefore love bright and warm positions. The exposure of the plant to the direct rays of the sun also allows the berries to take on a more lively and red color. Temperatures should not be below 16-18 degrees. In summer about 20 degrees, if it is warmer, the plant should be brought outdoors, in partial shade. During this season it is advisable to spray the plant in such a way as to guarantee it a moist soil, a fundamental condition for obtaining visually striking inflorescences and fruiting. It is also recommended to shelter the plant in case of particularly strong or cold drafts, as they are not well tolerated. The plant needs continuous air changes but too excessive winds could damage it permanently. Then place in more repaired areas if particular climatic conditions that are dangerous for the plant occur.


The ideal soil for the plant is formed by fertile soil, sand and peat so as to favor water drainage. Repotting must be carried out once the plant has produced its fruit and when the roots have occupied the entire space available to them inside the pot. As for the fertilizer, carry it out every 15 days throughout the year by diluting the liquid fertilizer in the irrigation water. Pruning is necessary when the solanum is grown for more than two years in a row. It is necessary to reduce the height of the plant by about 1/3.


The watering of the solanum must be abundant in the summer, because if the plant suffers from the lack of water the leaves and berries wither. Every day you have to wet the ground with warm water. In winter it is watered regularly so that the soil is always moist as long as the berries are present, then the quantity is reduced.


The multiplication of the plain occurs by sowing in March, distributing the seeds on the surface. They are covered with a layer of coarse sand; the containers should be kept wet, in the shade, at 16-21 degrees. After germination, the plants are discovered and kept in a bright place. When they are eight centimeters tall they are transplanted.

Solanum capsicastrum: Diseases and parasites

The red spider of the greenhouses stings the leaves and covers the upper page with small spots. Green aphids can infest young shoots in early summer. When there is a poor irrigation of the plant or the solanum capsicastrum grows in an environment that is too hot and dry compared to its ideal habitat, the leaves will wither while the berries will fall to the ground. In this case, it will be advisable to regulate the humidity of the soil and guarantee the plant a moist environment, frequently spraying the plant. On the contrary, when the watering is abandoned, the leaves may appear yellow. Another problem is related to the position in which the plant grows. If it looks dull and stunted, it means that it does not receive enough light to develop at its best. Change the position of the plant to get improvements.
