Water regularly, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot. In hot, dry weather, more frequent watering may be necessary.

Ensure good drainage to prevent waterlogged conditions, which Leptospermum scoparium dislikes.

Prune after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light tip pruning can be done throughout the growing season to promote denser foliage.

Avoid heavy pruning into old wood, as it may not regrow well.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Use a rooting hormone and plant in a well-draining medium. Keep cuttings moist and in a warm, humid environment.

Success rates can vary, so propagate multiple cuttings.

Repot young plants every 2-3 years in spring, or when root-bound. Use a well-draining potting mix, such as a blend of compost and coarse sand or perlite.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
