Watering, pruning, propagation, and repotting details from plant data
Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter to prevent root rot. Ensure good drainage to avoid waterlogged conditions.
Prune lightly after flowering to maintain shape and remove any dead or crossing branches. Major pruning is usually not necessary. This encourages bushier growth and can improve flowering in subsequent seasons.
Propagate from semi-hardwood cuttings taken in late summer or early autumn. Use a rooting hormone to increase success rates. Plant the cuttings in a well-draining compost mix and keep them in a warm, humid environment.
Repot young plants annually in spring, and mature plants every 2-3 years. Use a well-draining potting mix, such as a blend of peat, sand, and loam. Choose a pot that is only slightly larger than the current one.
