Why rot the cactus

Causes rot of the cactus can be inadequate care. This includes unsuitable soil that is hard to pass water and air, wrong size pot - too small or too large. If the soil is poorly permeable for water, it will stagnate on the surface, which causes rotting of the stem in the root zone. And the fact that the soil is not breathable, means that the roots cannot dry out they start to rot, and from them the rot spreading in the trunk. Too small a pot will result in the dieback of roots, decay of which can also switch on the stalk. And too much pot for a long time does not dry out and the roots begin to rot. The common reason for rot are too abundant and frequent watering, they are harmful even in summer the growth period of the cactus, and is contraindicated in the winter any moisture. The rot may start even after spraying in cold weather the moisture lingering on the stem of the cactus, causing it to rot, especially dangerous puddle accumulated around the point of growth. If the growth point had rotted, complete loss of many species of cactus — only a matter of time. Not all of them can form the faces and edges kids.

But it happens that the cactus starts to rot for no apparent reason even with proper watering and well-chosen soil pot. In this case, the cause of decay most often infected by pathogens: viruses, bacteria and lower fungi. To prevent contamination of cactus growing conditions had to be perfect, as the weakened at a bad environment the cactus has no power to fight infection. The types of bacterial rot that infects cacti, a variety. Common root rot when the roots begin dying under the action of microorganisms from the soil to decompose. The rot process is very slow and does not switch with the roots on living tissue. To stop it, is sufficient to prevent shedding a cactus with a solution of fungicide or bactericide drug.

Much more dangerous dry rot of cacti. Notice signs of decay when the disease is not found, the cactus slowly changes color and shape, and the inside pretty! Ways to cure dry rot yet, you can detect it when the plant can still be saved, too, is rarely. But preventive watering and spraying of fungicides and here is a good prevention. Also threat and stem wet rot is usually noticed only when wet black or white spot suddenly takes half of the stem under the skin. Up to this point, a cactus shows no signs of the disease, as it spreads too quickly. If in cutting the tops of the cactus rot at the growing point is not detected, the cuttings must be dried and to try to implant, saving thus a cactus.
