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.
If possible, the cactus better crop in a few instances. In the case of the death of one you can replace it with another.
