Problem with Weeping Cherry

Hi all, my weeping cherry tree, aged about ten years came into leaf and flowered as normal this year and suddenly most if the leaves have turned brown. Now noticed two other similar trees on the estate have done the same thing. Anyone any ideas? Thanks :confused:

 

Hi Pootle

Take a quick look at this link if you haven't already done so: http://www.gardenerscorner.co.uk/forum/threads/tree-health-diagnosis-a-self-help-guide.14478/

Post some pics of the affected trees, trying to get in as much detail of the problem as possible. Maybe we'll have a better idea of the problem then.

Cheers,
Matthew
