Water Citharexylum affine regularly, allowing the top 5-10 cm of soil to dry out between waterings. Reduce watering in cooler months. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Monitor soil moisture, especially in containers, as they dry out faster.

Prune Citharexylum affine in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain shape and encourage bushier growth.

Light pruning can be done after flowering to deadhead and tidy up the plant's appearance.

Propagate Citharexylum affine from semi-hardwood cuttings taken in summer. Use a rooting hormone to encourage root development.

Plant cuttings in a well-draining medium and keep them moist and in a warm, humid environment. Germination from seed is also possible.

Repot Citharexylum affine every 2-3 years, or when the plant becomes root-bound. Spring is the ideal time for repotting. Use a larger pot with fresh, well-draining potting mix.

Water thoroughly after repotting to help settle the soil around the roots.
