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. (…)

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 often and how much to water cactus (cacti) and succulent plants and which water to use

Watering is still one of the most debated themes among those who approach the cultivation of cacti and succulents in general. How much water do cacti want? When should succulent plants be watered? How often should succulents be watered? These above are just some of the most frequent questions – and I fly over, for obvious reasons, on another question that I have often heard asked: But should cacti be watered…?

Like any living thing, succulent plants need water. How, how much and when water depends on many factors, such as the time of the year, the place where you live (North or South Italy, for example?), temperatures, environmental humidity, the substrates you use, the size of the pots, and more… Before going into the details of watering, let us sure to definitively put aside false convictions legacy of who knows what experiences at the edge of the absurd. For example, let’s get the fact that cacti and succulent plants have to be watered with droppers or watered once in a blue moon.
