Water Sweet Osmanthus regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings to prevent root rot.

Reduce watering in winter when the plant's growth slows.

Prune Sweet Osmanthus after flowering to maintain its shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done at any time to control size.

Avoid heavy pruning in late summer as it can reduce flower buds.

Propagate Sweet Osmanthus from semi-hardwood cuttings taken in mid-summer. Select healthy shoots, dip the cut end in rooting hormone, and plant them in a well-draining potting mix.

Keep the cuttings moist and in a warm, humid environment until roots form.

Repot Sweet Osmanthus every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting, just before new growth begins. Use a slightly larger pot with fresh, well-draining potting soil.

Water thoroughly after repotting.
