Calathea


How much and how to irrigate the calathea


The calathea, otherwise known as "calatea", has tropical origins, the reason why the humidity of the surrounding environment covers a fundamental importance in its cultivation. The land must be checked very often. It is absolutely necessary to avoid that they are dry for too long. Consequently, watering must take place in a fairly regular manner, with significant water quantities in spring and summer and drastically decreased doses in winter. However, substrates should never be excessively soaked. This happens because the plant fears water stagnation very much which can cause very serious illnesses or lead to its death by root marking. Since environmental humidity is very important, it is essential to spray the calathea relatively often.

The cultivation and care of calathea



The cultivation of calathea is really quite complicated, given that it is a very delicate plant. Soils must be rich and light. To these it is necessary to add very little pumice stone in order to make them more draining. It is advisable to place the vase on expanded clay pebbles always well wet so that the roots can benefit from a slightly damp soil. At the same time, evaporation contributes not inconsiderably to the correct environmental humidity which is constantly adequate. The dried leaves must be periodically eliminated, extirpating them at the base. Leaf cleaning is very important and should be performed with a microfibre cloth. Every 2-3 years we need to proceed with repotting because the roots need a lot of space.

How and how much to properly fertilize the calathea



Fertilization is a very important operation in the cultivation of calathea. This must be implemented differently depending on the time of year and, consequently, on the vegetative phase of the plant. During the months of greater vigor of the calathea (normally corresponding to the months between April and September) it is necessary to proceed with a fertilization 2 times a month. The ideal fertilizer must be liquid, to be diluted according to the doses indicated on the packages, directly with the water used for irrigation. In winter, fertilization can be done simply once a month. The absolutely essential elements are nitrogen, phosphorus and potassium, although iron and copper must also be present. Especially the nitrogen favors the green parts of the plant.

Calathea: The ideal exposure and possible diseases of the calathea



The calathea is generally cultivated in pots in the home in fairly bright places (though not excessively). If strictly necessary, the calathea can also be found in the shade, but in this situation the leaves will be visibly less bright. Very important is the non-exposure to direct sunlight. Calathea is a very delicate plant and therefore frequently affected by diseases and parasites. Among the latter, the most devastating are the so-called "farinosa cocciniglia" and the "red spider". These must be treated with special pesticides. Some incorrect cultivation methods can bring problems. For example, excessive light causes the leaves to curl up, as well as a dry environment or an incorrect fertilization respectively cause dry leaves at the edges and extinguished. An increase in environmental humidity and a reconciliation are needed.
