Lisianthus

Irrigation of the lisianthus

This plant, endowed with beautiful flowers, needs regular watering during spring and summer, especially if there is no rainfall; it is necessary to proceed when the soil is completely dry, and to avoid water stagnation at all costs, which are very dangerous as they cause root rot. During autumn and winter, on the other hand, irrigation must be limited or suspended depending on the intensity and frequency of the rains. If the cultivation takes place in pots in a closed environment, it is necessary to administer water constantly: it is suggested to boil it and let it rest for one night before the operation, or to use the demineralized or rainwater one. It is recommended never to use water rich in limestone.

Tips for growing the plant


Lisianthus needs a light, soft soil characterized by good drainage, so as to avoid water stagnation. This plant multiplies through sowing: the seeds should be placed in a container filled with universal garden soil, peat and sand. After a year, the plant can be transplanted into a larger pot, or into the ground; it is perfect to adorn any type of environment. Periodically it is necessary to cut the diseased branches, the dry ones and those damaged by the cold and by parasites, using disinfected and sharp tools. If the cultivation takes place in the garden, it is suggested to mulch the soil annually with organic substances, such as straw, bark residues or dried leaves collected.

The fertilization of the lisiantus


Fertilization must be carried out during the spring, using a specific fertilizer for flowering plants, liquid, so as to integrate it with the irrigation water; the operation must be carried out every fortnight. A slow-release product can also be used, to be administered three times a year: the important thing is to provide the plant with the three essential macro-elements, namely potassium, nitrogen and phosphorus. The first offers fundamental support for the absorption of sugars and the synthesis of proteins, the second helps the growth of tissues, the third stimulates the processes of metabolism. Furthermore, no less important microelements such as magnesium, iron and manganese must not be missing; the appropriate fertilizer must also be selected on the basis of the chemical composition of the soil.

Lisianthus: Exposure, pests and diseases


The suggested exposure for Lisianthus is semi-shaded; it is preferable to avoid points directly hit by the sun’s rays, as well as excessively high or low temperatures. Furthermore, parasites such as aphids and scale insects are feared, authentic enemies of ornamental plants: both cause serious damage, as the former pierce the leaves to suck the sap, the latter cause widespread yellowing and decay of the foliage. Natural remedies are highly recommended, especially the white mineral oil against mealybugs and the garlic infusion against aphids. Furthermore, this plant can undergo fungal diseases such as powdery mildew, which causes the formation of a whitish mold on the affected parts and requires fungicides for the treatment.
