Water
Water regularly to keep the soil consistently moist, especially during dry periods. Reduce watering in winter when the plant is dormant. Ensure good drainage to prevent waterlogged roots, which can lead to root rot.
Also known as Fuzzy Mock Orange

Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during dry periods. Reduce watering in winter when the plant is dormant. Ensure good drainage to prevent waterlogged roots, which can lead to root rot.
Prune immediately after flowering to shape the shrub and encourage new growth for the following year. Remove any dead, damaged, or crossing branches. Light thinning can improve air circulation and flower production.
Propagate by softwood cuttings taken in early summer, or semi-hardwood cuttings in late summer. Cuttings should be treated with rooting hormone and placed in a moist, well-draining medium.
Layering is also an effective method.
Repot young plants every 1-2 years in spring before new growth starts. Mature plants generally do not require frequent repotting and can be refreshed by top-dressing with compost.
Ensure the new pot has adequate drainage.
