Here is the story of an Echinocactus grusonii born to lose but alive to win!

Would you throw away that specimen of Echinocactus grusonii you see in the photo above? Obviously the answer is no. Indeed, with such perfect thorns it would be a crime to let such a plant die. Nevertheless, a few years ago, when that plant was still a few months old seedling, I was about to throw it away! No, I hadn’t suddenly gone crazy, simply this plant, around 2015, was just one of the many grusonii seedlings obtained with a particularly lucky sowing (that is, characterized by high germination). What you see in the picture was the only seedling born from that sowing to have reached the stage of the first repotting in pitiful conditions, to the point that, convinced that it would not even pass the first repotting, I intended to throw it together with the sowing soil. Today, almost ten years later, that malformed, underdeveloped and sickly-looking seedling has become exactly as you see it in the photo I took a few days ago.

Here, in the following article, is the story of this plant, a plant that has been able to teach me an important lesson: never judge a book by its cover. In life as well as when dealing with Nature. (…)

Identical cacti in different substrates: extraordinary results of my test and the surprise of natural gypsum

To those wondering to what extent the substrate affects the growth of cacti; for those wondering if natural gypsum (also called agricultural gypsum) can be useful in the formation of robust thorns, this article will certainly be useful. Article which is nothing but the update of a small experiment – one of the many I do with my plants – which I started in July 2020 and which gave surprising results, amazing me first. Yes, because although the test sample is limited (six plants in all) and the results are therefore to be considered indicative and far from absolute, I must confess that I did not expect such a response just over two and a half years after the start of this test. It is known that substrates can literally make the difference in the growth of cacti and that natural gypsum (at least with some species of cacti) is an exceptional element, but it is with direct evidence, with the experimental method that we can really appreciate the impact of the soil in the growth of our succulents.

In this article, therefore, we go into the details of the experiment and see, after more than two and a half years, the results I obtained, which in my opinion are remarkable. (…)

The thorns of cacti: what they are for and why these plants have abandoned their leaves

Just as we find a wide variability of shapes and colors in the leaves of botanical species in general, which can be flat, fleshy, needle-shaped, ovate, heart-shaped, lanceolate, etc., we find the same variety in the thorns of cacti. Over the millennia, evolution has led to a remarkable range of shapes and colors, with spines that can have a papery or elastic and very fine consistency or, again, appear rigid, squat and short, long and broad, flat or tapered, sharp, hooked, black, gray, white, red, yellow. In general we can say that cacti are the only plants to have thorns, since in other specimens of the botanical world it is not entirely correct to speak of real thorns. Let’s think of the common roses: what we call thorns are actually excrescences that are produced along the stems, alternating with the leaves, which cacti do not have. So what exactly are thorns and how did cacti come to evolve with these “weapons” along the stem? What is the function of the spines in cacti? Why are some pointed while others are hooked? And why are there also cacti that have no thorns at all?

We will answer all these questions in the following article. (…)

Echinocactus texensis, an in-depth study of the “horse crippler”

The following is an in-depth article on the Echinocactus texensis species that I wrote some time ago and which, with my great pleasure, was published in the Cactus World magazine, published by the British Cactus & Succulents Society (BCSS). My thanks to editor Al Laius for the publication in the prestigious magazine. (…)

Repotting cacti: an experiment with different substrates to understand how potting soil affects growth

The fundamental factors for the growth of a plant are many: from exposure to watering; from fertilizations to temperatures. Among these factors, one of the most important – at least for cacti and succulent plants – is the substrate. The ideal soil for cacti must have at least two properties: it drains well and it dries quickly. (…)
