Water Boronia heterophylla moderately, allowing the soil to dry slightly between waterings. Avoid overwatering, as this can lead to root rot. Ensure good drainage, especially in pots.

Water more frequently during hot, dry periods and reduce watering in cooler months.

Prune Boronia heterophylla after flowering to maintain shape and encourage bushier growth. Remove spent flowers and trim back any leggy or straggly stems.

Avoid heavy pruning into old wood, as this can be detrimental to the plant's recovery and overall health.

Propagate Boronia heterophylla from semi-hardwood cuttings taken in late spring or early summer. Treat cuttings with rooting hormone and plant them in a well-draining propagation mix.

Keep them in a warm, humid environment until roots form.

Repot Kalgan Boronia every two to three years, preferably in spring, when the plant becomes root-bound. Use a well-draining potting mix, ideally formulated for native plants.

Handle the root ball gently to minimize disturbance and ensure new potting medium has good drainage.
