Pots and inert in the cultivation of succulents: can we recycle them or is it better to throw everything away?

Autumn comes into full swing and with the arrival of cold days, succulents plants require less “attention” from us. In this period, at least in Northern Italy or in middle-north Europe, the plants must already be in their winter location, protected from bad weather and excessive cold. There is time for repotting, since it is better to wait until mid or late winter for this type of operation. Watering is obviously suspended and all we have to do is carry out some preventive treatments to protect the succulents from fungi and mold during the winter months. So, what better time than this to dedicate yourself to tidying up the pots, jars, soil and materials needed for the substrates? And this is where a far from banal question arises for many growers: pots and aggregates (inert) are expensive, is it really worth throwing them away and buying new ones or is it possible to recycle all this material? The answer, clearly, is yes: recycling is a must, but be careful, under certain conditions and making sure that everything we are going to reuse is perfectly clean and free of parasites, spores, mold, dust, etc.

The following article is dedicated to this theme, which goes into detail about the cleaning and sterilization of vases (plastic and terracotta) and the materials used for the substrates (pumice, lapillus, gravel, etc.) which have been set aside after the last repottings carried out in recent months. (…)

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. (…)

A good cactus potting soil with materials readily available in any nursery? Here is how to do it

Surfing the Internet shows how easy it is now to find retailers of plant-growing materials. It is also true specifically for cacti and succulent plants: online, from skilled nurserymen to businesses that deal only in materials such as potting soil, pots, labels, etc., it is easy to get everything you need to grow. But what to do if we don’t want to buy online? If we need large quantities of materials, and shipping can only go up to a certain weight? If we prefer to provide directly by buying potting soil (everyone may have their reasons for this or that choice)? Do we rely on the ready-made potting soils usually offered by any well-stocked nursery or garden? Or is it better to do it ourselves, assembling the various materials as peat, pumice, and sand, based on our needs?

In this article we see how to make a proper substrate for use with any genre of cactus and, with appropriate adjustments, with succulents, in general. We will make it, and this is the point of this article, with materials that anyone can now easily find in any place (…).

When to pricking out cactus seedlings, how to do it correctly, and what potting soil to use

Speaking of cactus sowings, a classic question, and one not infrequently asked with a fair amount of (unnecessary) apprehension, is: after how long should seedlings be repotted? In other words, when do the young seedlings need to be repotted and perhaps divided into individual pots? Again, as with many other “cactophilies matters”, the answer depends on various cultivation factors. Based on experience, however, it is possible to give general indications useful to those who experiment with sowing for the first time.

Let’s see in detail, in this article, everything we need to know about this fundamental step for the proper growth of plants from our sowing. (…)

Six identical cacti in three different soils: a cultivation test with Mammillaria hahniana

Here is another test of mine. In the cultivation of cacti, a bit like with many other passions in life, there are two different approaches: a “static” approach, let’s say “contemplative” and “collecting”, and a “dynamic” one, experimental and inspired by an ever greater understanding of these plants. In this second approach (which is the one that has inspired my passion for years) the study of reliable texts, the comparison with other growers and, above all, the experimentation in the field, for example, working on potting media, exposure, cultivation techniques and more, are fundamental. Just growing plants – succulent or not – for years and years, in the same way, never changing the type of soil, exposure or method of cultivation is fine, mind you. Clearly, it’s perfect for those who only appreciate plants from an aesthetic or collecting point of view and have no particular demands. In short, it’s valid for those who are not interested in learning more and are not willing to take risks to improve and better understand the plants themselves.

Instead, the aim of “wild” cultivation is to obtain specimens as robust as possible, and with the same look to those that grow in the habitat (I write about this cultivation’s philosophy here). In addition to the documentation and possibly travel to observe the plants in nature, it is essential to engage in some experiments and be willing to question continuously, even if it could lose some specimens (not the valuable ones, of course).
