Arbutus unedo - strawberry arbutus problem

My strawberry arbutus started to develop black spots on the leaves in December. Many (most) of the leaves are now covered in black spots. It’s a 3 year old tree that is about 5 feet and was beautiful with tons of blossoms this fall that fed the hummingbirds this winter. Last spring it had a few leaves with these spots and I picked them off and it was fine all summer.
My question: Do you think this tree will survive? If I were to try to pick off all the black leaves the tree would be bare. Should I just leave it and hope for the best or is it done for?
I’ve attached a picture of one of the leaves.
Thanks

 

Arbutus menziesii (and Arctostaphylos columbiana, A. uva-ursi) is prone to blackening also. What they say about blackening of A. menziesii below is likely to apply to your situation as well.

Thanks for the article Ron. It sounds like I should just wait and see what happens. If the leaves drop hopefully new ones will grow.
