Pots and inert in the cultivation of succulents: can we recycle them or is it better to throw everything away?

Autumn comes into full swing and with the arrival of cold days, succulents plants require less “attention” from us. In this period, at least in Northern Italy or in middle-north Europe, the plants must already be in their winter location, protected from bad weather and excessive cold. There is time for repotting, since it is better to wait until mid or late winter for this type of operation. Watering is obviously suspended and all we have to do is carry out some preventive treatments to protect the succulents from fungi and mold during the winter months. So, what better time than this to dedicate yourself to tidying up the pots, jars, soil and materials needed for the substrates? And this is where a far from banal question arises for many growers: pots and aggregates (inert) are expensive, is it really worth throwing them away and buying new ones or is it possible to recycle all this material? The answer, clearly, is yes: recycling is a must, but be careful, under certain conditions and making sure that everything we are going to reuse is perfectly clean and free of parasites, spores, mold, dust, etc.

The following article is dedicated to this theme, which goes into detail about the cleaning and sterilization of vases (plastic and terracotta) and the materials used for the substrates (pumice, lapillus, gravel, etc.) which have been set aside after the last repottings carried out in recent months.

Towards summer: useful tips for taking care of cacti and succulents and avoiding nasty surprises

After an almost non-existent, anomalous and ugly spring (at least here in Italy), the temperatures have risen considerably and we are heading towards summer. In some respects, the most delicate period for cacti and succulents, i.e. the transition between the end of winter and the vegetative restart, is now behind us and the next few months will be rather “quiet” for those who cultivate these plants. In fact,  the main commitments will concern watering and fertilization, since repotting should by now be completed and treatments against pests and parasites can be given when necessary and not systematically. Even in the period of full vegetation of cacti and succulents, however, there are pitfalls and there are some elements and factors of cultivation to be taken into due consideration.

We see them in detail in the following article (…).

What are cactus ‘suckers’ or pups? Is it better to remove them? Do they affect flowering?

Let’s talk about cactus pups o cactus suckers. Some call them “branches”, others call them “new heads”. Some, more prosaically, call them “children” of the mother plant or “pups”. In all cases, they are new “protuberances” that sprout around the body of the main plant.

In cacti, as well as in agaves, this is a common phenomenon, and in some species, it never happens, in others it very easily happens, even with young plants. Attention: we are not talking about true seedlings born under the stem of the mother plant from seeds that have fallen from the latter, but about authentic new bodies that are attached to the main stem and sprout from the latter, and then grow steadily in size. The correct term is “suckers”, and anyone who grows cacti or has looked at this plant family in a nursery or botanical garden will have seen one or more suckers. Why do cacti produce suckers or pups, which genera are more likely to suck and are less so? And again, the most frequently asked question: is it true that pups steal energy from the mother plant and reduce flowering? Can the suckers themselves blossom? Another frequently asked question: is it better to leave them attached to the mother plant or remove them? Can they be used as cuttings to obtain new plants identical to the mother plant, and in the event of disease of the latter, can they be detached to save it and reproduce it? In other words, how to propagate cactus pups?

In this article, we take a closer look at the subject and answer all these questions (…).

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. (…)

Preparing cacti and succulents for spring: exposure, fertilizing, here’s what to do

Bright blooms, fleshy and brand-new leaves, sparkling spines sprouting from the vegetative apices: for succulent plants, spring represents a real rebirth. Here in Europe, the vegetative stasis that characterizes the winter of most succulent families ends between the second half of February and the beginning of March, when the plants gradually resume vegetation and reactivate the root system. For some families, the restart is evident: this is the case of Cactaceae, which already in February show new spines and often the first flower buds (genera such as Stenocactus, many species of Turbinicarpus, some Mammillaria, etc.). Also, leafy succulents such as Crassula, Echeveria, Portulacaria, Aloe, Adenium are well-known for producing new shoots, new branches and leaves. For other species as the Agavaceae family, the recovery is less evident: it slowly forms fresh sprouts at the centre of the apical rose, destined to be noticed only in a few months, when the separation of the true leaves will take place. Whether the recovery is sudden and flashy or slow and hidden, in March it’s essential to devote some extra care to succulents: in this way, it will be possible to obtain healthy and robust plants that show their full potential development and flowering.

Now let’s see everything we can do at this time of the year, especially if we don’t have a greenhouse and we grow on the windowsill, on the balcony, on a terrace or in the garden. With a warning: whatever you have to do, with succulents and cacti, you must not be in a hurry: hurry to water, hurry to treat, hurry to move the plants… Getting caught up in the rush, the anxiety, the fear of doing something wrong, is the best way to run into mistakes. So let’s see how to avoid them. (…)
