Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings.
In warmer months, more frequent watering may be necessary. Reduce watering in winter.
Prune after flowering to shape the plant and remove any dead or damaged stems. Avoid heavy pruning in late spring or summer, as this can remove the current season's flower buds.
Minimal pruning is often best to allow natural form.
Propagate by semi-hardwood cuttings taken in summer or hardwood cuttings taken in autumn. Cuttings should be treated with rooting hormone and placed in a moist, well-draining medium.
Cover with a plastic bag to maintain humidity.
Repot container-grown plants every 2-3 years in spring, or when they become root-bound. Use a good quality, free-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid waterlogging.
