A spring that is struggling to establish itself, temperatures that fluctuate continuously with sunny and very hot days and gloomy days with the thermometer plummeting. Above all, heavy rain almost every day for at least a week, at least here in the North Italy. Many of us have already moved their cacti and succulents outside, or have removed the winter protections (non-woven fabric or transparent sheets). Many are worried, some run for cover by bringing the plants indoors, others are undecided about what to do… Is it really the case to worry about the combination of low temperatures and persistent rain?

In this article, here are some reflections and the answer to the question that many of you are asking me these days, as always based on what I have learned in years of cultivation (…).

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. (…)
