A bit of past history------

Our block had Kwanzan Cherry Trees planted in front of every house in 1072.

The grew and dazzled us all with their pink tissue blooms for years and years.

After many years--the limbs and stems became hollow--due to (??) ants tunneling
or other bugs--or the tree's declining age.

The hollow branches and trunks became bird-nesting Condos--much to my amusement.
The returned year after year and guarded their holes with their lives. mostly sparrows and Starlings.

These trees have been on a decline for many years now. many homeowners have cut them down--
or have had them pruned back severely.

Last year--since mine looked near death--I decided to prune mine back as well. Rejuvenate it!

This spring--it did grow a bunch of new branches and leaves--and the starlings are still nesting in the
trunk's hollow innards. Must be like the grand palace of nesting spaces.....:o)

I just walked across the street to check out mu neighbor's trees--also cut back and re-growing--
but they are all OK. I snipped off all the affected tips of the branches ans will continue to do so.
The edges of these affected leaves are so tightly curled that I could not even un-curl them.
Was curious what may be inside the curls. One of them showed little black "seed-like" particles
inside the curled edges.

Can anyone tell me what is going on here???? This seems really weird!

Hope my multi-pictures post. There have been issues.... MNOPE! They did not.
Will do this two at a time....Glad I c/p my text. been doing that as a preventative
measure to losing all i have written.

#1--The tree as it is today.
#2--What looks like the beginning of the problem.

Will send other pics on following Post....

#1--Here is the tree as it looks today.
