Lithops: peculiarities and cultivation rules of the so-called “stone plants” or “living stones”

Also known as “stone plants” or “living stones”, Lithops are a genus of succulents that are always highly appreciated and widespread in cultivation and in collections. These are actually small plants, very particular, aesthetically pleasing and available in an infinite variety of colors and shades. Speaking of Lithops, one thing must be clarified immediately: they are non-cacti succulents. In other words, these plants do not belong to the large Cactaceae family (which includes cacti), but to the Mesembryanthemaceae family. In reality, according to many authors, to date the Mesembryanthemaceae family does not even exist anymore and the genera once attributable to it must be included in the Aizoaceae family. This vast family of succulent plants includes many other genera often widespread in cultivation or in nature also in Europe, such as Carpobrotus, Conophytum, Delosperma, Faucaria, Fenestraria, Lapidaria , Oscularia, Pleiospilos, Titanopsis and Trichodiadema.

Let’s deepen our knowledge of the Lithops genus in this article, in which we will also see the particular cultivation regime that these plants need in order to live in the Northern hemisphere. (…)

Marl as a substrate for cacti: is it really so good? How to use it and with which plants does it work

The use of marl as a substrate component for the cacti’s cultivation has been widespread for years, especially in Italy. Thanks to the studies and research conducted by my friend Andrea Cattabriga – grower, researcher and succulent expert at the international level. But what are we talking about, when we discuss marl? Quite simply, a greyish and highly friable rock, to the point of breaking up into flakes until it becomes powder. It’s used to create substrates for the cultivation of many cacti and some succulent plants when combined in some dosages with other materials such as quartzite, pumice, sand, gravel, lapilli, peat, field soil (clay).

In this article we explore the benefits of using marl in cactus cultivation, we see how to make a valid marl-based substrate, and we try to understand, above all, with which kinds of cacti this material can work and with which ones it should be avoided. (…)

Recognising succulent plants and cactus: a guide to identification and correct classification

Giving a succulent plant a scientific name, in other words correctly identifying a succulent plant, is far from simple. The classification, in general, the so-called taxonomy, is the prerogative of researchers, scholars, true enthusiasts and, in some cases, real maniacs of order. In that boundless land that is the classification of plants – and in the specific case of succulents – there is often great confusion, to the point that it is not uncommon to see the continuous re-denomination of the same plant, first included in one genus, then placed in another, then moved to another one. Some plants are classified in one way by some researchers and differently by others; some tend to simplify and reduce the number of genera, while others are inclined to divide plants as much as possible, according to their peculiarities, into several genera, species, subspecies, forms and varieties. Diatribes between authors and researchers about the classification of this or that plant are the order of the day. Thus, the common grower and the ‘collector’ of succulents are forced to rely on plant tags or try to classify them by comparing the specimen with pictures found on the Internet or in books.

In the following article, we see how to find your way and what you need to know to begin to identify and classify succulent plants. We also learn how to distinguish a cactus from any other succulent plant and how to identify the best-known succulent families. (…)

How to cultivate Euphorbia: tips to best care for these succulents loved by all the cactophiles

The succulent species belonging to the Euphorbia family (Euphorbiaceae) are appreciated and cultivated by many cacti lovers. The variability in the forms and some cultivation affinities with cacti make these plants an excellent alternative to “vary” the collections of succulents. However, it is essential to know the primary main needs of Euphorbias to grow them successfully. Euphorbiaceae is the fourth largest family of angiosperms, i.e. flowering plants. The Euphorbiaceae are divided into 5 subfamilies, 300 genera and 6.000 species, many of which are succulent. These plants have a very variable bearing: they can be in the form of small grasses, or in the form of real shrubs; they can be columnar or caespitose, very thorny or with a perfectly smooth stem. Also, they can hold leaves, but they can be devoid of them. Euphorbiaceae, unlike Cactaceae (exclusively originating from the Americas) come from almost every part of the world, except, of course, the Arctic and Antarctic areas. Some species come from Africa, others from the Americas or from Asia.

You can deepen the knowledge of Euphorbiaceae in the following article, with description, images, curiosities and cultivation techniques specific to this plant family. (…)

Schlumbergera, the “Christmas cactus”: how to make it bloom in all its abundance

As every year, between the end of November and the first half of December, my Schlumbergera blooms. As always, the blossoms are very abundant, with inflorescences on every “article” of the plants. These are very common, thornless cacti that I consider a classic “houseplant”, but no less interesting, than other genera. Let’s start by saying that Schlumbergera are for all intents and purposes cacti (family Cactaceae). They are epiphytic succulent plants that in nature live leaning on other plants that simply act as a support (epiphytes are therefore not parasitic plants). This genus, also commercially known as “Christmas cactus” because they bloom at this time of year (actually they bloom from November), is very beloved even among non-succulent enthusiasts.

In this article, we’ll learn how to cultivate the “Christmas Cactus”, for obtaining its abundant blooms without any problems. (…)
