Watering, pruning, propagation, and repotting details from plant data
Water sparingly once established. Allow the soil to dry out completely between waterings. Overwatering is a common cause of root rot, especially in well-drained soil.
Reduce watering significantly during winter dormancy to prevent fungal diseases.
Prune lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove any dead or straggly stems at any time.
Hard pruning in autumn can help the plant overwinter better and promote new growth in spring.
Propagate from semi-ripe cuttings taken in summer. Insert cuttings into a well-draining compost mix and keep them in a warm, humid environment. Alternatively, sow seeds in spring in a cold frame.
Cuttings typically root more reliably.
Repot young plants annually or biennially in spring before new growth begins. Established plants generally prefer to be slightly pot-bound and do not require frequent repotting.
Use a well-draining compost, such as a cactus or succulent mix.
