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. (…)

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. (…)

We take you with us on an exceptional “photo tour” in the Cactus Garden of Lanzarote

Characterized by its “lunar” landscape, the island of Lanzarote is an integral part of the Canary Islands, located off the coast of West Africa. The Canaries are under the dominion of Spain and are renowned for their always mild climate, splendid beaches and volcanic landscapes, especially on Lanzarote. Just the ideal climate has favored the creation, on this small island that extends over less than 900 square meters, the creation of a “Cactus Garden” famous all over the world, a real paradise for lovers of succulent plants.

Follow us on a “photo tour” through these botanical wonders. (…)

How to cultivate Melocactus, cacti that with age put on… the hat (“cephalium”)!

In the great botanical family of the Cactaceae the Melocactus represent a small “case apart”. In fact, these are cacti with a traditional globular shape tending towards a shorter cylinder as they age, but they have a peculiarity: over the years they “put on their hats”. In other words, the apex of these plants stops growing and a sort of “headdress” takes shape in its place, made up of a compact fluff mixed with thick and very thin thorns, usually red but sometimes white. This is the cephalium and this is where the flowers and fruits will come from. In a very bizarre way, over time it is only the cephalium that grows in height, so much so that the stems remain the same size, while the “hat” stretches towards the sky, giving these plants a truly unique appearance. The “however” of this story lies in the ease with which these cacti lose their roots and, even if they have not been affected by rot or parasites, they start to die. In other words, a  Melocactus  in full health often begins to slowly deteriorate and die, perhaps even taking two years, just because the root system has gone haywire and the plant has not been able to produce a new one.

Those who have been cultivating cacti for some time know it well:  Melocactus  are as fascinating as they are “capricious” and you have to come to terms with it. In this article we deepen the knowledge with this genus, in particular from the point of view of the needs, so as to grow robust specimens and limit losses as much as possible. (…)
