September is a brilliant month for all cacti, but pay attention to proper care ahead of autumn

Even in Northern Italy or, generally speaking, in Europe, September is usually a good time for cacti and succulent plants in general. Temperatures drop considerably, there is still plenty of light, and many plants start to vegetate again after the slowdown or stagnation of August when the highs are very high, and many succulents stop to save energy. However, September is also an important month ahead of the fall and winter season, when cacti and succulents stop growing altogether and allow themselves a long period of “rest” while waiting for the new growing season. It’s therefore decisive to accompany the plants on their journey and make the right treatments to arrive in the fall with healthy specimens and ready for the months of drought. Fundamental, for example, is the irrigation regime in this period.

In this article, we see what you need to do this month for keeping cacti and succulents in perfect health, even preparing them for winter diminishing the risk of rot and loss. (…)

Sudden changes in temperature and first colds: with cacti and succulents there is nothing to fear

From the highest peak to the lowest, about thirty degrees Celsius passes. This is the sudden change in temperature to which my succulents (90% cacti) have been exposed in recent weeks, almost all kept in the greenhouse which is still rigorously open 24 hours a day. All the Agaves remain outside the greenhouse, some Aloes, various Opuntia, Tephrocactus, Pediocactus, some Echinopsis and some cacti that I placed in the ground for experimentation. Can such sudden changes in temperature damage plants? Are nighttime lows starting to get too low for cacti and succulents in general?

There are many who wonder and, since I have received several messages in this sense, I have decided to write this short article to answer these questions. (…)

Succulents and cold: how to care for cactus in winter and the minimum temperatures tolerated

Do cacti resist frost? In winter, do succulent plants have to be kept indoors or can they stay outside? And what are the minimum winter temperatures they can tolerate? Even among experienced growers, the minimum temperatures of cacti and succulents are still debated today. I tackle the topic starting, as always, from my personal experience, which is my only way to have accurate data, found in the field, related to my system and my growing conditions, here in North of Italy. Let’s say right away that during winter I keep most of my plants in the greenhouse. It is a large greenhouse of 60 square meters and with a height, at the top, of 4 meters. These dimensions guarantee a satisfying volume of air, which in turn prevents moisture stagnation, the first real enemy of cacti and succulent plants in winter.

Let’s see, in the following article, the various factors that influence the resistance of cacti and succulents to cold. At the end of the article, you will also find a schedule with the minimum temperatures tolerated by the various families of succulents. (…)
