Watering, pruning, propagation, and repotting details from plant data
Water regularly when the top 2-3 cm of soil feels dry. Avoid overwatering, which can lead to root rot. Allow the soil to dry out slightly between waterings, especially during cooler months.
Good drainage is crucial to prevent waterlogged conditions.
Prune to maintain desired shape and size, and to remove any dead, damaged, or crossing branches. Light pruning can be done anytime.
For more significant shaping, prune in late winter or early spring before new growth begins. Remove spent flowers to encourage more blooms.
Propagate by seeds sown in spring or summer, or by semi-hardwood cuttings taken in summer. Seeds may require stratification or scarification.
Cuttings should be treated with rooting hormone and kept in a warm, humid environment until established.
Repot every 2-3 years in spring, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.
Water thoroughly after repotting.
