Water
Water regularly, keeping the soil consistently moist but not waterlogged, especially during establishment. Reduce watering in cooler months. Check the top 2-3 cm of soil; water when dry to the touch.
Overwatering can lead to root rot.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged, especially during establishment. Reduce watering in cooler months. Check the top 2-3 cm of soil; water when dry to the touch.
Overwatering can lead to root rot.
Prune after flowering to maintain shape and size. Remove any dead, diseased, or crossing branches. Light pruning can be done to encourage bushier growth. Heavy pruning is best avoided to prevent stress on the plant.
Propagate from semi-hardwood cuttings taken in summer. Use a rooting hormone to improve success rates. Plant cuttings in a well-draining potting mix and keep them in a warm, humid environment until roots develop.
Repot young plants every 2-3 years in spring, or when root-bound. Choose a pot that is slightly larger than the current one with good drainage. Use a well-draining, slightly acidic potting mix.
Avoid disturbing the root ball excessively.
