If the plant is grown in a container, repot the plant every 2-3 years to avoid the plant becoming root-bound. Remove any brown, mushy or woody roots during repotting.
Propagation of Cotyledon orbiculata L. var. spuria (L.) Toelken
Cotyledon orbiculata L. var. spuria (L.) Toelken is a succulent plant that can be propagated through different methods. The plant is commonly propagated during the spring and summer seasons when the plant is actively growing.
Leaf cutting propagation
One of the best ways to propagate Cotyledon orbiculata L. var. spuria (L.) Toelken is through leaf cutting. For this, choose a healthy mature leaf from the plant's stem and cut it with a sharp and clean knife. Leave the leaf to dry for a few days until the cutting surface calluses. Then, plant the cutting in succulent soil mix, water it, and place it in a well-lit area. After some weeks, the cutting will grow roots and produce new leaves, resulting in a new plant.
Stem cutting propagation
Cotyledon orbiculata L. var. spuria (L.) Toelken can also be propagated through stem cutting. Cut the plant stem that is healthy and mature and leave it to dry for a few days to form a callus. Then plant the cutting in succulent soil mix, watering it, and placing it in a well-lit area. Ensure the soil stays moist until the plant starts growing new leaves, indicating that the cutting has established itself and rooted.
Offsets/Division propagation
The plant produces offshoots or pups that sprout from the base of the mother plant called offsets. You can carefully remove these offsets when they have reached a reasonable size, ensuring that they have their roots. Then plant them in succulent soil mix and water them. The new plant will continue growing naturally once it has settled in its new location.
