Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 5 cm of soil feels dry. Allow the soil to dry out slightly between waterings, especially during winter dormancy. Avoid waterlogging, as this can lead to root rot.
Established plants are relatively drought-tolerant.
Prune after flowering to maintain shape and encourage bushier growth. Remove spent flower heads and any dead or crossing branches. Heavy pruning can be done in late winter or early spring before new growth begins.
Propagate from semi-hardwood cuttings taken in late summer or autumn. Dip cuttings in rooting hormone and plant in a well-draining potting mix. Keep moist and in a warm, humid environment until roots develop.
Repot young plants every 1-2 years in spring, or when root-bound. Use a pot with excellent drainage and a well-draining, native plant potting mix.
Avoid disturbing the roots excessively, as Grevilleas are sensitive to root disturbance.
