For any plant enthusiast, whether succulent or not, planting is an extremely important point of arrival. An arrival point which, in many cases, soon turns into a starting point which accompanies the enthusiast for most of his life. It is undeniable that there is no comparison between a purchased plant and one we have seen born, grow and develop from a tiny seed, even more if we have collected that seed from one of our plants. This is somewhat the “magic” of sowing: closing a circle born of a flower with another flower, the one produced by the plant originating from that first seed that we have been able to germinate, become a plant and lead to full maturity. And all this without going into detail about the satisfactions that are obtained by trying to select particularly interesting species, from flowers of unique colors to peculiar or almost unique thorns or stem shapes. As regards the procedure for sowing cacti and succulents, many novice growers “get lost” in the proverbial glass of water right after the phase least subject to our control, i.e. germination: we cannot in fact force a seed to germinate, although there are good practices that favor the birth of plants.

For many, however, the critical issues begin after that moment, that is to say in the first months of life of the plants, which are indeed delicate months because the seedlings are still weak and easily subject to rotting or parasitic attacks. It is above all to these growers that the following article is addressed, with a little “trick”, to be understood as advice, on how… to make life easier for seedlings and how to let them pass the first winter unharmed.

L'articolo Sowing cacti: how to prepare plants for the first winter and the “trick” to help them in the first few months proviene da Il fiore tra le spine.

Reproducing cacti starting from seeds is one of the best ways to get to know these plants in depth. Through sowing we can in fact observe the entire life cycle of the plant, from birth to the production of the first flower, to aging and death. Without forgetting the great satisfaction that the birth of seedlings is able to offer to those who practice sowing for the first time as well as those who have practiced it every year for decades. Not to mention the first flower: getting to see that the plant that we have given birth from a small seed, after two years or after twenty years depending on the species, finally opens its flower… it is priceless, there’s little to do. But before getting to all this – with regard to the sowing procedure, remember that on this site there is an entire section with at least fifteen articles dedicated to this topic at this link – you need to get the seeds. Banal, obvious. But without those you go nowhere. And there are two ways to get the seeds: buy them from specialized retailers (now almost exclusively online) or produce them with the manual pollination of your own plants. Or… simply collect the fruits that our plants have produced thanks to some pollinating insect, accepting the fact that two plants not of identical species may have been pollinated (and therefore we will be dealing with future hybrids), clean the fruits, store them and sow them in the spring.

In this article and in the related video we see how to clean and prepare the seeds for storage for future sowing. We sholud always remember that the seeds must be stored correctly, on pain of deterioration of the seeds and the consequent drastic drop in germinability. (…)

Ok, between one drop and another of condensation inside the bag we can see some tiny green dots. The seeds gave birth to the first seedlings, in short, our baby cacti. And now? How do we proceed with the sowing of cacti and succulent plants after the first germinations? Should we open the bags right away? Should we keep the seedlings in full light or is it better to place them in a sheltered place? Should we water regularly the seedlings or it’s better to let the potting soil dry out? And, finally, can we fertilize?

In this article, let’s see what to do once the seeds of cacti and succulents have germinated, in other words how to move correctly to help the plants grow and avoid making the work done with sowing in vain. (…)

L'articolo Sowing cacti and succulents: what to do when the first little plants are born proviene da Il fiore tra le spine.

Why damn yourself with sterilized soil, perfectly clean pots, fungicide, transparent bags and so on, when you can let our plants do everything related to sowing? Exactly as it happens in Nature, in short. Jokes aside, those who have many plants know well that finding themselves with perfectly formed seedlings inside the pots, next to the mother plants, is far from rare. Generally we notice it during repotting, when we can observe our succulents with particular attention, because the spontaneously born seedlings are small and tend to “camouflage” themselves with stones and aggregates in the substrate, or they are found so close to the stem of the mother plant to be invisible to a superficial look. Over the years, in the pots of my plants, I have often found germinated and autonomously grown seedlings, in particular of genera such as Astrophytum, Epithelantha, Thelocactus, Mammillaria. A couple of years ago I even found a small plant of Euphorbia obesa already well formed, grown among the pebbles outside the greenhouse, in the shade of a large pot containing an Agave. Today the Euphorbia is in a 5 centimeters pot inside the greenhouse and continues to grow regularly. I had to reluctantly remove it from the outside and place it in a pot to prevent the cold and damp winter in North Italy from killing it, otherwise I would have gladly let it grow where it was born.

In these days, during the repotting of some Astrophytum capricorne of my sowing, I have found many seedlings and various seedlings born and grown independently in the pots of the mother plants (you can already see some of them in the cover photo, above). Hence the idea of ​​documenting and analyzing “spontaneous sowing” in the following article. (…)

L'articolo Spontaneous sowing: when cacti do everything by themselves, just like in Nature proviene da Il fiore tra le spine.

Speaking of cactus sowings, a classic question, and one not infrequently asked with a fair amount of (unnecessary) apprehension, is: after how long should seedlings be repotted? In other words, when do the young seedlings need to be repotted and perhaps divided into individual pots? Again, as with many other “cactophilies matters”, the answer depends on various cultivation factors. Based on experience, however, it is possible to give general indications useful to those who experiment with sowing for the first time.

Let’s see in detail, in this article, everything we need to know about this fundamental step for the proper growth of plants from our sowing. (…)

L'articolo When to pricking out cactus seedlings, how to do it correctly, and what potting soil to use proviene da Il fiore tra le spine.

Based on the experiences of some growers, plants of the genus Ferocactus seem to appreciate the addition of calcareous material in the substrate. Above all, the thorns would benefit from it, which would be significantly strengthened compared to those of specimens grown in more “traditional” soils, for example the classic pumice, lapillus, peat mix in equal parts. Based on this consideration, I wanted to make an experiment with some of my sowings of Ferocactus acanthodes (seeds obtained from a dried fruit taken from an adult plant during a trip to Arizona) and Ferocactus latispinus. The acanthodes were born in 2013, while the latispinus are from 2010. Except for the seedling soil, which was based on peat, pumice and gravel, these plants grew up in the traditional compost with 30% fine peat and the rest pumice and lapillus in equal parts. I generally use this mix when I want to help seedlings develop more quickly, and then pass them into what I consider my “standard potting soil” made of sandy clay, pumice, gravel and 10% peat.

In the following article we see exactly what my experiment consists of, what type of soil I decided to use and above all we see the results with the photos taken two years after the test. (…)
