These plants do not need fertilizing, but if you want them to grow faster and form more daughter plants you can fertilize them with not a lot of prolonged action fertilizers. The best time to fertilize is spring.

Propagation

The uniqueness of the sempervivum heuffelii is that the child rosette is formed not by horizontal shoots but by the division of the mother plant. Usually, it is divided into 3 new outlets, resulting in a beautiful hump of plants.

To get new plants you need to separate them from the parent. Before separation, shake off all the soil from the roots.

You can use a sharp and clean knife to separate the cluster of rosettes, and it can also be disinfected. Cut rosettes lengthwise to leave a few roots or root tissue on each plant.

You can also split the sockets with your hands, make cuts at each socket and then tear them apart with your hands.

Dry the separated plants in the shade for 1-2 days to prevent rot.

You can then plant them in dry soil for succulents. If you keep split jovibarbs in the yard, then protect them from rain. Do not water them the week after separation. After 7 days, they can be watered with not much water, increase the amount of water gradually. You can expose them to the open sky a month after the separation and only if they have grown.

Otherwise, grow them undercover, controlling the amount of water until they begin to grow.

Jovibarba heuffelii can also be propagated by seeds. Sowing seeds of jovibarba is similar to sowing seeds of other species of sempervivum.
