How much and how to water the calathea

The calathea, otherwise also known as "calatea", has tropical origins, a reason why the humidity of the surrounding environment plays a fundamental role in its cultivation. Soils must be checked very often. It is absolutely necessary to avoid that they are dry for too long. Consequently, watering must take place fairly regularly, providing significant water quantities in spring and summer and drastically reduced doses in winter. However, the substrates must never be excessively soaked. This happens because the plant is very afraid of water stagnation which can cause very serious diseases or lead to its death through root rot. Since the environmental humidity is very important, it is essential to nebulize the calathea relatively often.

The cultivation of the calathea is really quite complicated, since 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 pot on always well wet expanded clay pebbles so that the roots can benefit from a soil that is always slightly moist. At the same time, evaporation contributes significantly to the correct environmental humidity which is constantly adequate. The dry leaves must be periodically eliminated, extirpating them at the base. The cleaning of the leaves is very important and to be performed with a microfiber cloth. Repotting should be done every 2-3 years because the roots require a lot of space.

How and how much to fertilize calathea correctly

Fertilization is a very important operation in the cultivation of calathea. This must be implemented differently according to the time of year in which you are and, consequently, to the vegetative phase of the plant. During the months of greatest vigor of the calathea (normally corresponding to the months between April and September) it is necessary to proceed with 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, fertilizing can be done simply once a month. The absolutely essential elements are nitrogen, phosphorus and potassium, although iron and copper must also be inevitable. Particularly nitrogen favors the green parts of the plant.

Calathea: The ideal exposure and possible diseases of the calathea

Calathea is usually grown in pots indoors in fairly bright places (although 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. Not exposed to direct sunlight is very important. Calathea is a very delicate plant and for this reason it is frequently affected by diseases and parasites. Among the latter, the most devastating are the so-called "mealy cochineal" and the "red spider". These must be treated with special pesticides. Some incorrect cultivation methods can lead to problems. For example, excessive light causes leaves to shrivel, just as dry surroundings or incorrect fertilization cause dry edges and dull leaves, respectively. An increase in ambient humidity and reconciliation are necessary.
