From above, from below, only the soil: how cacti and succulents get wet and how long we can do it

Let’s go against the trend, since the period is more suitable for talking about suspending watering than about how, how much, when a cactus or succulent plant is watered. The topic, however, is of primary importance and although already covered in a specific article published in the “early days” of this site, it deserves further study. And it deserves it, perhaps even more so, now that we are approaching the moment when (at least in Northern Italy and in Europe) it is appropriate to suspend irrigation. Knowing when to say stop wetting cacti and succulent plants in general is essential to avoid rot during the winter. Knowing in which ways it is possible to water our plants (from above, like rain, or from below, or wetting only the soil, etc.), knowing how many times to water them during the growing season, how to adjust with the various genres, how to relate watering to the substrates used and much more is equally fundamental.

This is therefore the reason for this article, which also answers the many questions on this topic – how are succulent watered, how often are they watered, in which way? etc. – placed at any time of the year by novice growers (and not only novice). Not to mention that, if we want to go into detail, there are cacti and succulents that really appreciate some winter watering. Didn’t you know? More and more this article will be for you.

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.

Expanded clay and peat: are they really two materials to avoid when growing succulents?

Hated, mistreated, seen with contempt, often carefully avoided. Expanded clay and peat are two highly contested and criticized elements among growers of succulent plants and cacti in particular. Net of the chatter from the Internet, are these really two materials that should be forgotten with the cultivation of this type of plant? The question remains open and every grower has his reasons, but there is a fact: on the Net, as far as expanded clay and peat are concerned, everything is said. Above all, it is said that they retain humidity excessively and for this reason they should be banned from the cultivation of cacti and succulents in general. It is said that they favor the onset of rot, that they do not let the roots breathe and much more. Why then do many serious nurserymen (and expert growers with them) still make extensive use of those elements? Simply because, as in many factors of cultivation, the point is not so much the material itself, but the type of use that is made of it.

In this article, let’s try to understand if expanded clay and peat are really such “dangerous” materials for cacti and succulents, if and how they can be used and what their real pros and cons are. (…)

How to grow cactus: the handbook with the 10 things you absolutely need to know to avoid mistakes

Full sun? But what do you want to know, the window on the landing is enough! Substrate? I buy it ready at the supermarket, it’s perfect. The pots? The smaller the better: never leave more than half a centimeter between the plant and the edge of the pot… And so on, by dint of amenities, false beliefs, hearsay phrases that rapidly becomes dogma because… because it was said by that guy on Facebook and it’s immediately clear that he’s someone who knows about it because his videos has the right lights and Kubrick seems to have done the editing for him. Joking aside, how much nonsense do we still have to hear today about the cultivation of cacti? How many improvised “influencers” ride the crest of social media driven by the Mistral of likes (yes, likes, which in jargon are called “the metrics of vanity”…) and, supported by legions of followers and big thumbs up, they deliver lessons and conferences winking from the monitors, revealing “5 fantastic tricks you don’t know about cacti” or “how to go from seed to flowering plant in 35 seconds”. Or, with an attitude halfway between the conspiratorial and the revealer of esoteric secrets, they promise to teach you everything, absolutely everything about the cultivation of these splendid plants. Then, perhaps, you dig a little and discover that the influencer on duty has been growing cacti for 2 or 3 years – a gift from grandmother -, keeps them next to the PC or television (“you know, they absorb magnetic rays”), he can’t distinguish a Rebutia from a Begonia and has never bothered to leaf through any book on cacti and succulents. There are also influencers for plants, right? No. There are likeable and well-prepared characters, there are pretty faces who know something, but there is also a lot of “fluff” (forgive the old reporter’s term). So much wrong information, so much confusion and so much unpreparedness.

So, without any desire to offer you “The Word” with this article, here is a handbook, a list of ten things you need to know (or you should already know!) if you really want to cultivate your cacti in the best possible way. Without tricks or deceptions: here we are at the fundamentals, come on. But without these you go nowhere. And I am convinced that even those who, scrolling through the 10 points will say “ah yes, I know” ten times, will find in this handbook a useful tool for reviewing, asking themselves a few more questions and pushing themselves to improve. And rest assured, what follows does not come from the web, but from 30 years of experience in the field, of experiments and failures, from discussions with growers and scholars far more expert than me and from reading a few dozen manuals in Italian, English, French, Spanish (and also German, although in that case, I confess, I limited myself to photographs and captions, not knowing the Teutonic language!)

Seramis, an alternative material for growing cacti and succulent plants: pros and cons

Recently, on the social channels connected to the site, I published a short video in which I repot an Astrophytum asterias in a substrate composed solely of Seramis. Following that video, many asked me for information on this particular material with its characteristic orange colour, in fact little used in the cultivation of succulents and not easily available in small nurseries. I have had the opportunity to use Seramis in the past in the cultivation of some cactaceae and my experience has been decidedly positive (although, as a porous inert material, in my opinion pumice remains the best material ever) and it is also for this reason that I recently employed it for the Astrophytum subject of the video (video that you can also find at the end of this article).

Answering many questions received in recent weeks, let’s see in the following article what exactly Seramis is, what are the strengths and weaknesses of this material and what can be its use with succulents and, in particular, with cacti. (…)
