Where to Plant
If you live in a zone that gets colder than 30 F, it’s best to plant this plant in a container that can be brought indoors. It does well in both full and partial sun.
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.
Cuttings
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.
Leaves
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.
