Water regularly, especially during establishment and dry periods. Creek Bottlebrush prefers consistently moist soil but can tolerate short periods of drought once mature. Ensure good drainage to prevent root rot.

Reduce watering in cooler months.

Prune after flowering to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done year-round. Heavy pruning should be avoided as it can reduce flowering.

Propagate from semi-hardwood cuttings taken in summer or autumn. Cuttings should be treated with rooting hormone and placed in a well-draining potting mix in a warm, humid environment.

Seed propagation is also possible but may result in variation.

Repot young plants annually or as needed when root-bound, preferably in spring. Use a well-draining potting mix. Mature plants generally do not require frequent repotting and prefer to be slightly root-bound.

Ensure the new pot is only slightly larger than the old one.
