Watering, pruning, propagation, and repotting details from plant data
Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. Reduce watering in cooler months when the plant's growth slows down. Ensure good drainage in the pot.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.
Heavy pruning can be done in late winter or early spring before new growth begins to invigorate the plant.
Propagate by semi-hardwood cuttings taken in summer. Dip cuttings in rooting hormone and plant in a moist, well-draining potting mix.
Maintain high humidity and warmth until roots form, which can take several weeks to months.
Repot every 2-3 years or when the plant becomes root-bound, preferably in spring. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
Water thoroughly after repotting.
