Thanks for the reply Ken. I have decided banksias are annoying to layer, they like to heal, ALOT! This guy has been recut 3 times. Each time it fully healed across. The lasttime I recut, I also halved the height of the top of the tree as I think it was pushing to much energy down causing it to heal. Seemed to have worked
now fingers crossed it pulls through...
The base is terrific and growing really healthy after being slip potted. Will get repotted around Christmas.
