Planted last September but is looking rather stressed now. I feel I give it plenty of water. Any ideas on what I can try?
I'm located in Perth, Tree is on north side of house so gets plenty of sun. Soil was typically sandy so added compost, bentonite clay and a few other ingredients (as per Fu's lawn prep guide).
As you can see from the pictures leaves curled and some have these black spots. All that said it still seems to be growing, sprouting new shoots/ leaves.
