Sedum flowering

Question: sedum flowering

Good evening, I have a problem and I hope you can help me: I own several sedum palmeri plants.
Some have bloomed quite well, while others have bloomed half the pot, leaving the rest only with leaves and without flowers. How is this possible? Moreover I see on other balconies blooms of this plant much more abundant than mine, which are ever more sparse.
What am I doing wrong?

Answer: sedum flowering

Dear Gaia,
the sedum are a genus belonging to the crassulaceae family, there are about six hundred species, all succulent, widespread in nature throughout the northern hemisphere; in particular, the sedum that you cultivate, sedum palmeri, is native to Mexico and completely naturalized in Italy, where it is present in some regions in the wild, and is cultivated in many areas for its great ability to adapt, even in gardens and very low maintenance terraces. It is a very easy plant to cultivate, which gives excellent results even when it is not cultivated in the best way; clear that to have healthy and luxuriant plants and an abundant flowering every year, it is necessary to follow some small rules, so that the plant is always in full health. First of all, what usually influences the amount of flowers produced by a plant is sunlight: i sedum palmeri they love a good amount of direct sunlight, even if they can survive without problems even in partial shade or in the shade and do not like too much direct light for many hours a day, especially in summer; therefore, if your plants are in a position where they have little light, it is quite normal for them to produce few flowers, in particular they will tend to produce very long racemes, to reach the light, which therefore deviate greatly from the base of the vegetation, which therefore it remains completely bare of flowers. The sedum also survive with little soil (they are often seen even on dry stone walls, among pebbles or bricks), and often they are satisfied with the water received from the rains; on a terrace in a vase, however, things can be very different with respect to land and water that a plant can receive on a dry-stone wall or between pebbles; in the long run, with the passage of animals, the earth present in the pots tends to completely exhaust the mineral salts contained in it, and therefore, even if we are growing a succulent, which requires few mineral salts, it is opportune to supply sporadically (about one every 15-20 days) of the fertilizer, from March to September, choosing a specific one for succulent plants, that is poor in nitrogen and rich in potassium, which also stimulates flowering. In addition to the quality of the soil, consider that, although succulent plants can survive drought for a long time, this does not mean that they can live forever without water; if therefore your pots are positioned so as to receive the water of the weather, the plants will act best; if, on the other hand, the jars are sheltered, and therefore they are not wet in any way, to see your lush sedum, you will have to water, from March to September, but only when the ground is well dry. One last thing, when planting ground cover plants in pots, it often happens that the pot becomes too crowded, causing a non-optimal development of every single plant; It is therefore appropriate to periodically divide the sedum, so that they receive the space they need in the vase; the rosettes that you remove on these occasions (usually after flowering) can be used to prepare new vases.
