Cacti must be fertilized regularly. Often when we buy one or more small ones, in those tiny pots, we care a lot about watering them so that they do not lack water, but we forget a little to give them "food". For a time, one, maybe two years, nothing will happen, because they will take the nutrients they find in the substrate.
Later, however, we will notice that they grow more slowly, that they stop flowering, and / or that they become more vulnerable to pests and / or microorganisms that cause diseases, such as fungi or viruses. For this reason, it is important to know how to choose cactus fertilizer so that they do not have nutritional deficiencies.

What compost is good for cacti?
The fertilizer that is used it has to be rich in nutrients, but it is advised that it be low in nitrogen since an excess of this will stimulate the growth of the plants, and it is easy for the body of the cactus to weaken. In addition, it is important to differentiate liquid fertilizers or fertilizers from granulated or powdered ones.
Thus, liquids are very fast effective, since the nutrients are available to the roots, and therefore to the plants almost at the time of application. In addition, they do not interfere with the absorption or filtration of water, so that the drainage capacity of the substrate or soil remains intact.
Granulated or powder fertilizers they may be quick to work as well, but this is rarely the case. These are usually released slowly and for a long time, so that the cacti can absorb them little by little. But they have a problem, and that is that unlike liquids, they can worsen the drainage capacity of the earth. For this reason, should only be applied to plants that are in the ground, and not potted.
