You can plant in an area of your garden that gets 6 hours of sunlight a day. If you must bring it indoors during the winter, place it in a room that gets a lot of sunlight, such as near a southern-facing window.

How to Propagate Crassula rupestris

Stems and leaves can be used to grow crassula rupestris.


Use a sterile, sharp knife or pair of scissors to grow the rupestris. Allow the main plant’s stem to callous for several days before placing it on well-draining soil. Water whenever the soil has dried out.


Pull a leaf from the mother plant. You will have a smaller chance of success if you don’t keep the leaf on the stem.

Allow the leaf to dry out for a few days so that the end callouses over, and then place on well-draining soil. Water whenever the soil is dry.
