If you are thinking of making onecomposition of succulents in pots, know that the houseleeks, including the Sempervivum tectorum species, have an imposing root system. If you want to do one composition of succulentsyou will want to insert different kinds ofeverlastingand do not grow specimens of the genus sempervivum with other succulents in the same container.

Sempervivum tectorum: care and cultivation

The Sempervivum tectorum species, just like the other specimens of the genus sempervivum, needs fewcareso much so that it can almost be left to itself!

It adapts to the most diverse terrains. If you want to cultivate thealways live in potsyou can use a specific soil for succulents. If, on the other hand, you plant in the garden, you will have to carry out a preliminary tillage of the soil only if you have too clayey and asphyxiated soil.

If you have clayey soil, you will need to correct it by digging deep, burying soil with leaves, black lapillus or pumice, coarse river sand ... until you obtain a soil capable of draining the water without causing rot to the plants.

The Sempervivum tectorum species does not have particular climatic needs: it resists cold and heat well. Only humid heat can create suffering for the plant. This is why, if you live in Southern Italy where there are mild and rainy autumns and winters, it is better to place the plant away from the rains or add a temporary roof.

The plant can survive without any irrigation. Only if grown in pots will it be necessary to wet the soil abundantly in summer (once a week). The soil must be completely dry between one irrigation and the next.

Fertilizer

In the open ground the plant does not need fertilizer, however, if the cultivation is in pots it might be advisable to fertilize with a low nitrogen fertilizer. An ideal formulation could be: NPK 5-15-30.
