Towards summer: useful tips for taking care of cacti and succulents and avoiding nasty surprises

After an almost non-existent, anomalous and ugly spring (at least here in Italy), the temperatures have risen considerably and we are heading towards summer. In some respects, the most delicate period for cacti and succulents, i.e. the transition between the end of winter and the vegetative restart, is now behind us and the next few months will be rather “quiet” for those who cultivate these plants. In fact,  the main commitments will concern watering and fertilization, since repotting should by now be completed and treatments against pests and parasites can be given when necessary and not systematically. Even in the period of full vegetation of cacti and succulents, however, there are pitfalls and there are some elements and factors of cultivation to be taken into due consideration.

We see them in detail in the following article (…).

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 (…).

What are cactus ‘suckers’ or pups? Is it better to remove them? Do they affect flowering?

Let’s talk about cactus pups o cactus suckers. Some call them “branches”, others call them “new heads”. Some, more prosaically, call them “children” of the mother plant or “pups”. In all cases, they are new “protuberances” that sprout around the body of the main plant.

In cacti, as well as in agaves, this is a common phenomenon, and in some species, it never happens, in others it very easily happens, even with young plants. Attention: we are not talking about true seedlings born under the stem of the mother plant from seeds that have fallen from the latter, but about authentic new bodies that are attached to the main stem and sprout from the latter, and then grow steadily in size. The correct term is “suckers”, and anyone who grows cacti or has looked at this plant family in a nursery or botanical garden will have seen one or more suckers. Why do cacti produce suckers or pups, which genera are more likely to suck and are less so? And again, the most frequently asked question: is it true that pups steal energy from the mother plant and reduce flowering? Can the suckers themselves blossom? Another frequently asked question: is it better to leave them attached to the mother plant or remove them? Can they be used as cuttings to obtain new plants identical to the mother plant, and in the event of disease of the latter, can they be detached to save it and reproduce it? In other words, how to propagate cactus pups?

In this article, we take a closer look at the subject and answer all these questions (…).

Compositions with succulents: how to choose plants and what is important to know

Better to set the record straight right away: the topic of compositions has very little to do with the spirit of this site. In fact, we are just the opposite: on the one hand, the spartan approach that aims to obtain plants similar to those in habitat and that is the basis of my cultivation method; on the other hand, cultivation for aesthetic purposes only, which I do not practice but which we know very well is widespread. But life, as you know, is never all black or all white; some nuance must always be there…. So, here is an article accompanied by a video of mine on how to make a simple succulent plant arrangement. After all, an eye for aesthetics never hurts, and even I, who love “lived-in,” nature-like plants, do not disdain a well-done composition, as long as it is no-frills and made with respect for the needs of the individual plants. Warning: the theme may seem obvious and the subject matter very simple, but it’s not so and you will understand why in the next lines.  Assuming that in plant compositions everyone is free to do what they want, this is just an aesthetic field, that is, related to personal taste, if you want to make compositions that will last over time and that will not make the plants suffer or die quickly, it will be wise to choose the right essences judiciously and place them in the correct substrate.

Let’s see in this article how to correctly choose the plants for our compositions (…)

When the cactus “spins”: what is etiolation, how to prevent it and contain the damage

An etiolated cactus is a plant with an unnatural habit and which has suffered from a more or less serious lack of light. The phenomenon is unfortunately irreversible but it is possible to prevent etiolation and stop it.

Who hasn’t happened at least once to observe in some office, apartment or even non-specialized nurseries (or garden) those cone-shaped cacti with thin spines and pale green stem? Cacti with a rounded base and an elongated apex, tapered to the point of giving the plant an almost pyramidal shape. The novice grower may think that is the normal bearing of the plant, but the grower with some experience – or even just a critical mind – usually is horrified at such plants. If anything, he or she may be saddened, because he or she knows full well that that is not the normal bearing of the cacti at all, but simply the outcome of what is technically called “etiolation” or, commonly, “spinning.” By the way, the photos above and those accompanying this article are of plants in a nursery and not mine, I want to make that clear right away!

Why does this fate happen to some cacti? How to avoid cactus etiolation and how to distinguish it from normal growth or from growth that is simply dissimilar to normal? Is it possible to remedy the damage caused by spinning on a cactus? We answer these questions in the following article. (…)
