cherry tree problems

Hi,

This tree was given to us as a wedding present, and was supposed to be the same age as our relationship, so I really need to stop it dying!

It has some sort of leaf disease, which seems to leave holes on the leaves. There are a few spots, but mainly the side of a leaf just disappears. I have now spotted it on the young cherries too (see attachments).

we had poor cherries last year, but thought it was birds! suspect it was unwell last year too!

Any ideas what is wrong with it, and what I should do to fix it???

I have looked at various websites, but nothing seems to match. There are slight yellow spots on some leaves, but not enough to make the side of the leaf fall off!

PS we live in a very clayey soil area.

 

Seems like leaf mine damage or winter moth, nothing at all to worry about.

 

It looks more like a combination of snail damage and scorch to me. Neither is life threatening, so don`t worry too much.
