Most succulent plants develop a compact root system with slow growth, which is why they are grown in small containers; despite these characteristics even succulent plants need repotting: both to change the container, when it becomes too small to contain the entire root system, and to renew the soil it contains.
Generally the repotting is carried out when the plants are in vegetative rest, and therefore traditionally from autumn until the end of winter, or early spring.
For plants succulents young people should also intervene every year; for the larger specimens, in pots already for a long time, we can intervene with the repotting also every 2-3 years or more.
Before taking the plant out of the old pot, prepare a new container if necessary; most plants succulents they prefer small containers, where the radical apparatus does not have too much space available; therefore we choose a vase that has a diameter slightly greater than that in which the plant is contained.
We also prepare an ideal soil for our plants; the succulents generally do not like moist or wet soils, therefore they need a decidedly very well drained and aerated soil. We can prepare a compote suitable for all succulents by mixing a part of universal soil that is not very peaty, with a part of well-washed river sand and a part of incoherent material, such as lapillus, pozzolana or pumice stone.
The stone component is essential for aerating the soil as best as possible, and allowing water to flow freely when we water it or when the plants are subjected to the elements.
The sand that is used is that of the river, because any salt residues can quickly bring the plants to death; moreover it is important that the sand is washed, to remove the residual silt or dust that would otherwise go to excessively compact the cultivation substrate.
Succulent repotting: Repotting
We extract our succulent from the jar taking care not to damage it, in the case of plants covered with down or thorns we can simply grab them using a cloth, or even polystyrene or cardboard, which we wrap around the stem, being careful not to over-tighten.
Once the plant has been extracted from the pot, we try to remove the soil that lurks between the roots; we take advantage of this moment to remove any parasites present between the roots, such as the root cochineal, and also parts of ruined or darkened roots, which could rot inside the vase.
Once the root system has been cleaned, place a thin layer of pumice stone (or other incoherent material) in the jar, then fill part of the jar with the substrate prepared previously, position our plant and fill the jar until it reaches the plant's collar.
We avoid in any way to cover the plant beyond the collar, otherwise we could favor the development of harmful rots.
After filling the jar, let's beat it a few times on the ground, to fill any air pockets formed in the substrate.
We place the pot in a cool and dry place, and avoid watering for about 7-10 days, to allow the plant to settle.
