Discussions about propagating from cuttings, seeds, air layers etc. Going on a dig (Yamadori) or thinking of importing? Discuss how, when and where here.
Spring and summer are the most usual times for layering. You generally won't get much progress as the weather cools but hopefully the layers will stay alive and be ready to grow roots as soon as the weather starts to warm up in spring.
The lilly pilly might still be active enough over winter to grow some roots.
