Apparently they came into full leaf and flowered, but have become defoliated recently.

 

Leaf spot anyone?

 

Treatment?

 

Any advice would be gratefully received. :thumbup:

Where did frost damage come from :confused1: Look at the leaves, and its so widespread . Even young trees in the garden centre's have got it, and most nurseries. Why plant inspectors don't pick it up I will never know ?

Eddy, that's not a dig in any way, the Bacterial infection is widespread in the UK, effecting about 75% of most Prunus avium and ornamental and fruiting varieties , (my own estimate at %) for me, looking at the photos its a very simple diagnosis .

Cos there's less than a dozen inspectors for England and Wales?

Fair one, but its not a difficult one to detect, and it has been around for a long time, you would by now hope not to see it in your local garden center, but i know i could go tomorrow and buy it , already established on Prunus at any one of my local garden centers . :thumbdown:
