Succulents outdoor all year? Here are the ones that resist and the story of my “resurrected” Echinocereus

Many succulents, whether cacti or other succulent families, tolerate the cold well. Not all cacti and not all succulents, of course, but many species can face the winter without problems even outdoors not only in the regions of Southern Italy, but also in many European states or in Asia and in northern America. The story of the Echinocereus laui in the photo above contains a very important lesson from this point of view. With the exception of epiphytic cacti (Schlumbergera, Epiphyllum, Rhipsalis, etc.), for species such as Melocactus and Discocactus and for succulent plants native to Madagascar or some African regions (Adenium obesum, Uncarina, Aloe, many Euphorbia and almost all Asclepiadaceae), many succulents can spend the winter months at temperatures close to zero Celsius degrees, as long as the soil remains dry at least from October to the end of March. However, there are some cacti and some succulents capable of surprising us and surviving the rigors of winter without problems, in some cases even in damp soil (therefore partly exposed to the elements).

Among these, some species of Echinocereus, as the plant you see in the photo, which I had given up for dead, and whitch instead was reborn after two winters spent entirely outdoors, exposed to the cold and humidity whitch characterizes northern Italy. In this article here is the history of this plant and a brief overview of the succulent plants that we can keep outdoors all year round. (…)

Where to keep succulents in winter? Outside, on a landing or in the house? A practical handbook

 

A practical handbook and an in-depth analysis on a much debated topic among those who grow succulent and/or cactus plants. Here’s what you’ll find by reading this article, designed specifically to help those who, with the first drops in temperatures, are starting to wonder where to place their succulents when the real cold arrives. Unless you have a greenhouse, perhaps equipped with a burner regulated by a thermostat, the question is in fact more than pertinent: during the winter it is better to keep the succulent plants outside (sheltered from the rain), or in a cool environment such as a landing, an internal staircase or even a garage? Or should we bring all the plants indoors? It is good to clarify immediately that the answer to these questions cannot be tranchant or “absolute”: obviously the correct winter location depends on many factors, starting from the area in which the plants are grown (North or South Italy? North or South Europe? Sea or high mountains?) to arrive at the type of plant (Cactaceae, succulent native to Africa or Madagascar? Sempervivum, Crassula, Euphorbia?). In short, the range of cases is very broad and as always there are no absolute rules. Luckily there are many fixed points and many precautions that should be respected to ensure that our succulents pass the winter securely and take advantage of the vegetative stasis to be able to flower again the following year.

The following article answers these questions, and you will also find an indication of the correct measures to be taken to ensure that cacti and succulents overwinter in the best possible way, have abundant blooms and, above all, you’ll find a practical handbook with an indication of the best location for cacti and succulents organized in alphabetical order, so as to facilitate the identification of the plant, understand in which minimum temperature range it can stay and where it can be placed (for example outside, on a landing, or directly inside the house).

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. (…)

How a cactus changes depending on the type of cultivation: the difference made by soil and exposure

When they say that a picture is better than words. In this case, there are three photos, but the concept doesn’t change, and the difference between a cactus grown in a “natural” (or “wild”) way and one with a “garden-style”, based on basic notions and beliefs is quite evident. The plants I’m writing about are Ferocactus latispinus obtained from a 2012 sowing of mine. From that same planting, I’ve got at least forty plants. Over the years, I have given away some of them, but most are still with me and are growing beautifully. It’s important to point out that these are plants born from seeds contained in a single fruit (gift of a dear friend), sown the same day and grown over the years in the same conditions, i.e. in my greenhouse, in standard soil (pumice, lapilli and peat in equal parts), watered and fertilized with the same frequency. This is to say that the starting conditions, including the genetics and the grower’s hand, are the same. And yet, as you can see from the photo above, where the three plants (three at random of the twenty-five or so that I have kept for myself) are side by side, they show remarkable differences, at least to the discerning eye and the grower with a minimum of experience.

So let’s see, in this article, how and why different cultivation regimens, assumed as a whole and not just limited to the soil, affect so much the final result and really make the difference between a cactus grown and cultivated in any garden or generic nursery and a cactus grown by an enthusiast or an expert.

How much light do cactus need to grow well? The importance of sun and air and a summary table

Light is fundamental for every living being, starting with plants. This is obvious, but we cannot ignore it if we want to grow cacti and succulent plants in general. Plants, moreover, that often need many hours of light per day; in some cases direct or non-filtered light, in others not straight but equally intense daylight. In fact, there are succulent plants that, if placed in full sun, slow down growth, burn and even die. On the contrary, many succulent plants and many cacti, if they do not receive the right amount of direct light, will have stunted growth, with weak thorns and elongated stems.

In this article, we see what we need to know about the right exposure of cacti and succulent plants in general. Also, at the end of this article, you find a table summarizing the type of exposure needed by the main families of succulents. (…)
