It’s time for… testing. Between the end of December and the end of February, as soon as I have time, I dedicate myself to repotting the plants in the greenhouse. Obviously I only repot plants in stasis, with very dry soil, postponing the change of pot to spring for the plants that I keep in vegetation in winter, perhaps outdoors (but still in pots and not in the ground, of course). Today I flared and planted about fifty plants that I obtained by sowing in natural light and heat. Some of them were born in 2014, others in 2016 (but already large enough to be repotted). It was an opportunity to start a useful test on various types of soil to understand how this affects the growth of some specific species of cacti.

Let’s see in the following article what exactly this experiment on the substrate consists of and let’s see, thanks to the photographic update two years after repotting, how the plants have grown. (…)
