Repotting cactus: the classic mix of pumice, lapillus and peat to speed up growth

I generally start repotting from mid-December onwards, to finish within the first few months of the new year. This year, considering the number of plants I sow that need repotting, I started well in advance. Despite the still high temperatures for the period, in fact, the plants are already in stasis and it is possible to proceed without problems. The repotting period is one of the most debated topics, together with the composition of the growing soils: there are those who repot only plants in vegetation, those only in spring, those during the winter and those who repot at any time of the year. Let’s say that there isn’t a fixed rule: over the years, I have repotted practically in all seasons, according to needs, and I have never encountered any problems. The important thing is to stick to that only really useful precaution which is to avoid watering immediately after repotting. It is necessary to give the damaged or cut roots time to heal in dry soil during repotting, so as to avoid the risk that they may trigger rot. The rest is a matter of choices. Personally I prefer to repot and change the soil to the plants during the winter season, or in any case when the cacti and succulents are in vegetative stasis, for example just before spring, so that several weeks elapse between repotting and the first watering. I’ve been following this “rule” for years and have never had a problem. Of course, it may happen that some plants find it difficult to restart after repotting, to the point of being stuck even for a whole year, but this can happen by repotting at any time. Let’s not forget that repotting is in any case a significant “stress” for plants. This is also why I prefer winter, when the cacti are at rest and the effects of repotting are less “traumatic”.

Let’s explore the topic of repotting and substrates for cacti, in particular the “standard” soil based on pumice, lapillus and peat in equal parts, in the following article. (…)

How to make cactus and succulent plants bloom: what you need to know and what tricks to use

How to get cactus to bloom is one of the most frequently asked questions among succulent plant enthusiasts. Here are the precautions to take to make our cacti flourish.

Colourful, flashy, ephemeral. Cactus blooms are sudden bursts of energy. Often the buds develop in a few days to open within few hours, amazing the newcomers to the cultivation of these plants and, above all, those who are not familiar with succulents. In these last few years, I have noticed that there is a lot of misinformation about cacti, in particular about their blooms. Those who do not cultivate these plants can even be surprised that they can bloom, no more or less than the specimens of all the other plant families, forgetting that the flower is the basis of the reproduction of almost all plants. Others are impressed to learn that even cacti can bloom in abundance and several times during the growing season, thinking perhaps that the flowering of a cactus is an exceptional event, almost unique. Nothing could be more wrong: all the cacti regularly bloom, and if there are relatively stingy species, that can produce few flowers for limited periods during the year, there are also really generous species, able to give blooms several times for entire months (for example Echinopsis, Astrophytum, Strombocactus, Gymnocalycium, Trichocereus).

In the following article we see in detail how to make cacti and succulent plants bloom abundantly. (…)

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. (…)

When and how fertilize cactus and succulent plants to have aboundant blooms

First of all: why should we fertilize our cacti and succulent plants? Let’s say right away that fertilization (or fertilisation, or manuring or mineral nutrition) is necessary for any plant grown in pots, since the amount of soil available is limited and, sooner or later, nutrients will begin to run low. Fertilizer nourishes the plant, enriching the soil of those elements which, through the time, are absorbed by the plant or washed away by the waterings. Succulent plants should be regularly fertilized to ensure that the right quantity of nutrients is always available during the growing season. For cacti and succulents, however, generic fertilizers should not be used. In other words, a fertilizer commonly used for ornamental, leafy or fruit plants is not at all appropriate for a cactus plant. It is necessary to resort to specific fertilizers, specially balanced for the succulents. Otherwise, the risk is to irreparably compromise the growth and the physical appearance of the plant, making it weak and radically different from the specimens of the same species that grow in the wild.

In the following article we will go deeper into the subject, let’s see what elements succulents need, how the suitable fertilizer must be composed and how much to fertilize during the year. (…)

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. (…)
