Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering during winter dormancy. Ensure good drainage to prevent root rot, as this plant dislikes soggy conditions. Overwatering can lead to fungal issues.
Prune to maintain shape and encourage bushier growth. Remove dead or leggy stems as needed. Light pruning after flowering can promote more blooms. Heavy pruning can be done in early spring before new growth begins.
Easily propagated from stem cuttings taken in spring or summer. Dip cuttings in rooting hormone and plant in moist, well-draining soil.
Keep the soil consistently moist and the cuttings in a warm, bright location until established.
Repot every 1-2 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot that is slightly larger than the previous one.
This helps provide fresh nutrients and space for root growth.
