Spring is here, what to do with cacti and succulents? All out or is it better to wait?

Spring, the so-called beautiful season, has now begun: what to do with cacti and succulents? Should you take plants kept indoors outside during the winter? Remove covers or layers of non-woven fabric? Resume watering? Fertilize plants?

Spring is the season of recovery for all plants, and succulents are no exception. Many species are already in full bloom, such as Stenocactus, Strombocactus, many Turbinicarpus and several Mammillaria. Be careful, however, there is a difference between flowering and vegetative growth: a plant can flower even if it has not fully resumed vegetating. Simply, this is its flowering period and the plant respects it even if it is still coming out of the winter “dormancy” state. As regards temperatures, obviously there is a big difference based on the area in which it is grown, so in some regions of the South the night-time minimums can already be above 10 degrees, while in the North we still have relatively low values, around 2 or 3 degrees. This factor is fundamental to understanding whether we can move our plants outside or not. Equally important is the time to resume watering. Can we start watering cacti and succulents these days or is it better to wait a little longer? Finally: with the start of the summer, is it necessary to carry out some treatments with plant protection products or can this practice be avoided?

Let’s see everything in detail in the following article, so as to move correctly and avoid problems or rot damaging the plants. (…)

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!)

Summer is coming: seasonal care for cacti and succulents, watering and aestivation

Summer is a relatively quiet season for those who grow cacti. Things to do, in fact, are not that many. Preventive treatments have already been done, and repotting, although repotting can be done at any time if necessary, should be suspended at this time, when the plants are in vegetation and in full bloom. Fertilizations should also be stopped at this time, confining them to spring and September. Overall, the bulk of the work in the weeks from mid-June through August focuses on watering, which will need to be calibrated according to the species being grown. In some cases, with certain plants, it will be appropriate to suspend them altogether to avoid stagnation and rot. Indeed, there are plants that vegetate well even in these months and plants that slow down their vegetation. Still others, in the warmer months, such as July and August, stop vegetation altogether to resume growth at the time of September, as soon as the maximum temperatures have dropped slightly. This phenomenon, the halting of vegetation coinciding with the hottest weeks, is called “summering,” and it is good to know its effects to avoid risks in cultivation.

In the following article we look in detail at what we have to do in the run-up to summer to best prepare cacti and succulents and avoid problems. (…)

How much light do cactus need to grow well? The importance of sun and air and a summary table

Light is fundamental for every living being, starting with plants. This is obvious, but we cannot ignore it if we want to grow cacti and succulent plants in general. Plants, moreover, that often need many hours of light per day; in some cases direct or non-filtered light, in others not straight but equally intense daylight. In fact, there are succulent plants that, if placed in full sun, slow down growth, burn and even die. On the contrary, many succulent plants and many cacti, if they do not receive the right amount of direct light, will have stunted growth, with weak thorns and elongated stems.

In this article, we see what we need to know about the right exposure of cacti and succulent plants in general. Also, at the end of this article, you find a table summarizing the type of exposure needed by the main families of succulents. (…)
