Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogging. Ensure good drainage to avoid root rot, especially in containers.
Consistent moisture is key for healthy growth.
Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain the shrub's shape and health.
Light shaping can be done after flowering to encourage bushier growth and remove spent blooms.
Propagate from semi-hardwood cuttings taken in summer. Dip cuttings in rooting hormone and plant in a well-draining, moist propagation mix. Maintain high humidity and warmth. Rooting can take several weeks to months.
Repot established plants every 2-3 years in spring, or when root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one.
Water thoroughly after repotting to help settle the soil.
