I have a cherry blossom tree on the front lawn and for the past few years it has started to get holes in the leaves as shown in the pic click hereit has got progressively worse especially this year. Does anyone know what it is and how to treat it?

Having looked at your link I think it is the original one my picture is almost identical to your original post so it looks like Prunus Necrotic Ringspot Virus so is there no treatment?

If I remember correctly a virus attacks at cell level making it untreatable.

Hopefully someone will prove me wrong.

This site doesn't mention PNRV in trees but does say this....

"#If a plant is infected with virus..remove and burn the plant."

I really hope its not a virus, they are such lovely trees.

There's no cure for PNRV, but some trees will put up a good fight. It's more serious in Cherry and Plum orchards, where an outbreak can reduce fruit crops by up to 50%.

All you can do is keep your tree pruned to admit plenty of light and air to the centre, and hope.

Hi FE thanks for the reply. Would I be better to prune the tree right back and should I do it asap or wait till the growing season is over?
