Grafting cactus: when a succulent plant can be grafted and what is the correct procedure to follow

In cacti as well as in many other botanical families, grafting is a common practice, usually adopted to grow delicate plants more easily and to speed up the growth rates of the plants themselves. In short, it consists of combining a delicate plant with a robust plant, which will provide the former with nourishment and encourage its growth.

Those who follow this site know well that the “philosophy” underlying the cultivation of cacti and succulents adopted by me is based on obtaining plants as similar as possible to those in the habitat. My approach to cultivation is essentially simple and spartan and is inspired by the so-called “wild” cultivation method, which precisely has the aim of obtaining cacti with a natural, lived-in appearance and, overall, as similar as possible to what plants have in nature. It is for this reason that it is not my habit to practice grafting cacti, which can certainly be a useful technique in many cases but which does not lead, from an aesthetic point of view, to obtaining specimens similar to those that grow in their habitat. This is not only due to the very fact that one plant grows grafted onto another, but also due to the fact that grafted plants tend over time to take on very different characteristics from those of plants grown naturally. In fact, grafted plants can have much more swollen stems, sometimes deformed compared to the norm and even the thorns can grow differently.

However, given the high number of growers who practice grafting (also useful for speeding up the growth of cacti and making them flower so as to be able to pollinate them to have seeds with which to reproduce them) or who do not disdain the cultivation of grafted plants and considered many questions that they reached me over time via email, here, for completeness, is an article that deals with this practice and explains how to graft cacti (…)

Succulent plants, a small guide for those approaching this world: the simplest species to grow

The world of succulent plants is extremely vast. It follows that the cultivation needs of individual succulents can vary considerably from family to family and from genus to genus. With a concrete example, a cactus (plant belonging to the Cactaceae family) has extremely different cultivation needs compared to an Adenium obesum (succulent plant belonging to the Apocynaceae family). Likewise, large differences in cultivation can occur within the same family or between different genera of a single family. Here too is an example: an Ariocarpus (genus belonging to the Cactaceae) requires a cultivation regime, understood as substrate, watering, etc. very different from an Echinopsis (genus always belonging to the Cactaceae).

Without dwelling too much on the broad field of plant classification (here, if you want, you will find an article dedicated to this topic) and taking it for granted that the term “succulent plants” refers both to cacti and to many other succulent botanical families whose specimens have a different appearance from any other cactus, we are addressing a very “heartfelt” topic among novice growers. Even the grower who boasts a good knowledge of a given family, however, may find the following article useful, which recommends succulent plants (belonging to various botanical families) that are less demanding, more robust and simple to grow and therefore more suitable for those who are only now approaching the world of succulents. (…)

Succulents outdoor all year? Here are the ones that resist and the story of my “resurrected” Echinocereus

Many succulents, whether cacti or other succulent families, tolerate the cold well. Not all cacti and not all succulents, of course, but many species can face the winter without problems even outdoors not only in the regions of Southern Italy, but also in many European states or in Asia and in northern America. The story of the Echinocereus laui in the photo above contains a very important lesson from this point of view. With the exception of epiphytic cacti (Schlumbergera, Epiphyllum, Rhipsalis, etc.), for species such as Melocactus and Discocactus and for succulent plants native to Madagascar or some African regions (Adenium obesum, Uncarina, Aloe, many Euphorbia and almost all Asclepiadaceae), many succulents can spend the winter months at temperatures close to zero Celsius degrees, as long as the soil remains dry at least from October to the end of March. However, there are some cacti and some succulents capable of surprising us and surviving the rigors of winter without problems, in some cases even in damp soil (therefore partly exposed to the elements).

Among these, some species of Echinocereus, as the plant you see in the photo, which I had given up for dead, and whitch instead was reborn after two winters spent entirely outdoors, exposed to the cold and humidity whitch characterizes northern Italy. In this article here is the history of this plant and a brief overview of the succulent plants that we can keep outdoors all year round. (…)

Splendid but… untouchable: Echeveria laui, when the sky is reflected in a succulent plant

Admire it as long as you want, but don’t you dare touch it! Even a simple caress is able to disfigure this masterpiece of Nature, altering the suggestion of wax – or the sensation of painting – that this succulent plant returns to the eye. Echeveria laui is a very widespread Crassulacea and also appreciated by those who mainly grow cacti. Its appearance, on the other hand, is undeniably attractive and it is difficult for a specimen of this succulent to go unnoticed. Either for that splendid blue color, or for the compact shape of the rosette, with the blunt tips or, again, for its uniqueness even within the Echeveria genus, which also boasts various species with specimens with pale blue leaves. The fact is that it is impossible not to admire the perfection of a well-cultivated (and above all never touched!) specimen of this particular species.

In this article we deepen our knowledge of Echeveria laui, we understand why it has this appearance which is certainly not unique in the world of succulents but undoubtedly peculiar, and we learn how to grow it correctly. (…)

Where to keep succulents in winter? Outside, on a landing or in the house? A practical handbook

 

A practical handbook and an in-depth analysis on a much debated topic among those who grow succulent and/or cactus plants. Here’s what you’ll find by reading this article, designed specifically to help those who, with the first drops in temperatures, are starting to wonder where to place their succulents when the real cold arrives. Unless you have a greenhouse, perhaps equipped with a burner regulated by a thermostat, the question is in fact more than pertinent: during the winter it is better to keep the succulent plants outside (sheltered from the rain), or in a cool environment such as a landing, an internal staircase or even a garage? Or should we bring all the plants indoors? It is good to clarify immediately that the answer to these questions cannot be tranchant or “absolute”: obviously the correct winter location depends on many factors, starting from the area in which the plants are grown (North or South Italy? North or South Europe? Sea or high mountains?) to arrive at the type of plant (Cactaceae, succulent native to Africa or Madagascar? Sempervivum, Crassula, Euphorbia?). In short, the range of cases is very broad and as always there are no absolute rules. Luckily there are many fixed points and many precautions that should be respected to ensure that our succulents pass the winter securely and take advantage of the vegetative stasis to be able to flower again the following year.

The following article answers these questions, and you will also find an indication of the correct measures to be taken to ensure that cacti and succulents overwinter in the best possible way, have abundant blooms and, above all, you’ll find a practical handbook with an indication of the best location for cacti and succulents organized in alphabetical order, so as to facilitate the identification of the plant, understand in which minimum temperature range it can stay and where it can be placed (for example outside, on a landing, or directly inside the house).
