What about Honey Suckle? There are lots of different types that you could consider. Have attached an image for you :)
I have quite a lot of Lilly Pilly trees and quite a few are strting to be infested with a pest. I assume I could kill them with a pesticide of some type, but would much prefer an organic method of fixing/controlling this.
Does anyone know what these are? Any ideas on how to fix it?
