How to prune a cactus
You will need
  • - a sharp knife or blade;
  • plate;
  • - a pot for transplanting;
  • - drainage;
  • - the ground;
  • - sand.
Make a cut from the old plant. If the cactus is quite long (15 cm or more) it can be cut from the top. If the plant is not very high, pull it out of the ground to cut the top part was easier and more convenient. Now take a sharp knife or razor blade and confident movement, cut off the top part of the cactus (about 6-8 cm). Too small of a cut should not be done because the plant may simply wither or rot. But a huge "cucumber" to get involved is not necessary. Select the medium size.
Undercut your slice in the manner of a sharpened pencil. The fact that after drying, the soft tissue begins to get involved in the tenderloin. If you leave the slice flat in a week he could easily look like a reverse funnel. To obtain the roots of such a surface, buried her in the ground, is extremely problematic. That is why the edges of the cactus need to be turned.
The same sharp knife you used for cutting, gently astrogate edges to the cactus looked like a pencil. To get involved in worth it. Enough "peg" to 1.5-2 cm Remember the proportions. If you treat your slice 2/3 of a pencil and 1/3 will be left in its original form, the chances of rooting is extremely small. Optimal is the proportion of the slice to the plant in the ratio 1:3.
Dry your miracle during the week. Do not be afraid that during this time the cactus will die without water and soil. Drying is a prerequisite for successful rooting. Cactus leave on the plate or in any other capacity, to wet cut dry and a little drawn in.
If you did everything correctly, pointed part should be almost flush with the original edges of your cut. Now the cactus can be planted into the substrate. Pour into the pot drainage, and top soil for cacti, and then a small layer of sand. Your "pencil" gently screwed into the center. Now it remains only to regularly moisten the soil in the pot and wait for rooting.
Do not place freshly cut cacti directly into the water or substrate. Of course, there are rare cases when they take root and thus, but most often just the cactus rots. The cut must be pre-dried.
Useful advice
If possible, the cactus better crop in a few instances. In the case of the death of one you can replace it with another.

Advice 2 : Why rot the cactus

Among flower growers believed that the cactus is very undemanding, will survive in any conditions and never hurts. But professionals know that this is not so.
Cactus rots
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.
