Rooted cuttings are a very simple way to propagate Australian finger lime. Cuttings should be between 2-4 inches and a rooting hormone should be used to speed up root formation. Keep the cuttings in a humid environment away from direct light until roots have been established. Cuttings will take around two weeks to start developing roots. Slowly acclimate over 1-2 weeks before exposing to direct sunlight. Trees propagated by cuttings are most suitable for containers and should not be planted in the ground.
