Watering, pruning, propagation, and repotting details from plant data
Water regularly when the top 2-3 cm of soil feels dry. Ensure good drainage to prevent waterlogged roots. Reduce watering frequency during cooler months but do not allow the soil to dry out completely.
Consistent moisture is key for optimal flowering.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks.
For a more significant rejuvenation, prune back harder in early spring before new growth begins, stimulating fresh, vigorous shoots.
Propagate from semi-hardwood cuttings taken in summer. Dip cuttings in rooting hormone and plant in a well-draining, moist potting mix. Maintain high humidity and warmth until roots develop, usually within 4-6 weeks.
Repot young plants annually in spring. Mature plants can be repotted every 2-3 years or when root-bound. Use a good quality, well-draining potting mix. Choose a pot one size larger than the current one.
