When the cactus “explodes” from too much water: how to avoid cracks on the stem

Succulent plants, and cacti in particular, have evolved to accumulate water reserves and thus be able to deal with long periods of drought. In their natural habitats, cacti are subject to sudden changes in temperature between night and day, but also to an alternation between periods of total drought and periods of great water availability. In the sub-desert regions of the southern United States (California, Arizona, Texas, Nevada, etc.), as well as in Mexico, Central America and Latin America (Chile and Argentina, for example), during the growing season, corresponding to spring and summer, the hot, dry days are often abruptly interrupted by heavy downpours. If in nature the plants know how to manage these conditions without particular problems, in cultivation it can happen that the transition from the stasis season to the growth season, if accompanied by an overly “decisive” resumption of irrigation, gives rise to the phenomenon of splitting of the stems.

In this article we see how and why this phenomenon can occur, how to remedy it to prevent the plant from contracting rot and above all how to avoid splits. (…)

Cactus without roots: how to save the plant and which soil to use to get it back to full health

Cacti can be capricious plants, expecially because of their roots. It can happen, in fact, that despite all the cares we dedicate to one of our succulent plants, it stops growing, stops producing thorns and flowers and, in the space of a few weeks (or months, in some cases), begins to deteriorate, deflating and turning yellow. At the origin of this phenomenon, not always a pathology exists, as a bacterial attack that can cause the rot. In the same way, the cause may not necessarily be due to a parasitic attack. If you look closely at the plant, for example, you might not find any traces of spider mite or mealybug, the two main pests of succulents. With experience I have learned that when a plant, even apparently healthy (i.e. not affected by parasites or bacteria) and grown in the best conditions (light, air, watering, soil, etc..) begins to deteriorate deflating and yellowing despite watering, it is always better to remove it from the pot and check the health of the root system. More often than we might think, the problem can hide just there, below the collar.

In this article we will see everything we can do to save a cactus or a succulent plant in evident difficulty or when, after having flared it, we realize that it has lost all or part of its roots. (…)

From the Anza-Borrego park in California, stunning photos of Ferocactus in their habitat

The genus Ferocactus is among the most appreciated and cultivated by cactus enthusiasts. It is the thorny cactus par excellence, with strong and long thorns, often hooked, and with age it can reach considerable size even if cultivated in pots. Let’s see, in this wonderful gallery of photos taken by Ben Grillo, how these plants grow in their natural habitat. (…)

The distribution of cacti and succulents in the world: maps with the states where they grow

Have you always wondered what part of the world your cactus or succulent plant comes from? From the Americas or maybe from Asia? From Africa or Europe? The topic of succulent plant distribution is vast and very intricate. However, to begin to simplify, we can say that all cacti are native to the Americas, while succulent plants in general (i.e. non-cactaceous succulents) come from different parts of the world.

In this article and in the two large maps attached, we see how cacti and non-cacti succulents are distributed around the world. We see in particular from which geographical areas the succulents originally evolved. (…)
