How to Grow and Care
These are not difficult plants to grow well, provided they get enough sunlight and warmth. Like all succulents, they cannot tolerate sitting in water and if you err, do it on the side of too little water. Use a specialized soil mix designed for cacti and succulents.
Repot as needed, preferably during the warm season. To repot a Desert Rose, make sure the soil is dry before repotting, then gently remove the plant from the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide and antibacterial solution. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
