My toyon tree (Heteromeles arbutifolia) seems to be dying and I'm trying to figure out if it can still be saved or if I should get rid of it. It starts off with some reddish brown blotches on the leaves, then over time the leaves become all brown and dead. The berries look dried up too. I've lived here 3 yrs and cut off a few branches the first year that had this problem, but it's been affecting more and more branches every year. I tried spraying with some Neem oil fungicide last year and again this spring but it didn't seem to do any good. Here's a picture of the beginning stage where the berries are shrivelled but the leaves just have spots on them:
