This isn't a test, its just a bit of fun. They all were in great health otherwise I wouldn't have cut back so hard. Only fertilizer I use is Powerfeed for natives about every 4 weeks or so when I can be bothered remembering, and Osmocote slow release.

FYI just for the casuarina, they were all cut so that there was at least one shoot below the cut to avoid any possible die-back. The optimum time for cutting back casys hard, in my opinion is November but I didn't have the guts to do them last year without the level of sun they get now.
Most cuts on all trees were about 2cm or so in diameter, so all were on older wood and in the case of the casys : fissured bark.
I have no idea, but my

is
banking on Banksia.
