Repotting a succulent plant: what to do afterwards and how long to wait before wetting the soil

Anyone who has been cultivating succulent plants for a long time – whether they are cacti or other succulents such as Crassula, Euphorbia, etc. – knows well what should be done after transplanting, and he certainly knows that these plants should not be watered immediately at the end of this operation. However, there is repotting and repotting: there is the “invasive” one and the one that involves simply moving a plant from one pot to another. There is repotting which involves total cleaning of the roots and that which involves only a superficial cleaning of the old soil. In short, there are many situations and one can proceed in various ways. However, there are some fixed points and they must be respected if we want to avoid the risk that following this operation the plant will go into stress or, in the worst case, die following a rot that started right from the roots.

This is why this article, certainly useful to the novice, can prove equally useful to the long-term grower. In fact, here we will see the various types of possible repotting, the precautions to use and, above all, what to do (not only from the point of view of watering) once the repotting of a succulent is finished.

Substrate, loam, soil mix: which is the best soil for cactus and succulent plants?

I may look like a mordant, but I want to clear the field of misunderstandings and false myths: the right soil for cacti does not exist. There are many types of soil (or composts, substrates, mixtures, the question does not change) and there are genera that prefer certain substances and others that require more. Established this and removed one of the first Faq (Frequently Asked Questions) by cacti enthusiasts to the first arms – “Which is the best soil for my cactus?” – it can be said on the contrary that on the one hand there are the characteristics that a good soil for cactus must necessarily have; on the other hand the needs of the single plants. The question was simple and the related answer was given by italian cacti expert Giuseppe Lodi, who, after observing “the butts of roots of certain imports” and having noticed how these were encrusted with clay loam, suggested a base soil absolutely natural and versatile: “You can start from a mixture of common clay loam (field or garden), coarse sand and leaf soil, in equal parts. Of these three components none of them can be enough, alone” (Giuseppe Lodi, “Le mie piante grasse” – Edagricole).

Except perhaps for the difficult availability of the loam of leaves (be careful to go for the woods and get bags of decomposed foliage: there are fines for collections of this kind), the recipe provided by the Italian pioneer in the cultivation of cacti and succulents was more than sensible, as well as experienced. Considering the difficulty of finding the loam of leaves (Lodi suggested leaves of beech or chestnut), that moreover must be well decomposed (and it may contain fungi and bacteria dangerous for the plants), this element can be replaced by good quality peat, sieved fine, without lumps and filaments. Too bad that over the years we have forgotten Lodi advice to focus everything on what for many is still the standard substrate of peat, lapillus and pumice in equal parts, standard enough to fit any kind and species of succulent.

In the following article now we see which is the best substrate for growing cacti and succulent plants based on my experience over the years with proofs and experiments on various mixtures. (…)
