Joanie - thanks for the feedback, you've had some great thoughts but I don't think we've got the cause yet.

I repoted both this spring - didn't cut much off the roots. Thier roots looked very healthy - no sign of root rot. The soil is very good draining. I've also got a lot of other trees in the same soil that are doing well. So I didn't think this was the problem.

In terms of fertilizing - I haven't fertilized either of these yet this year - though I was a little aggressive with the tree last year. I didn't apply much to the cutting as It didn't seem healthly last year.

No bugs on them - I haven't used any insecticide either.

Other thoughts?

I think I'm going to treat as if black-spot.
