Cherry leaf diagnosis

[Dean Lofthouse]

Does anyone know if this leaf shows a lack of nutrients or nutrient. This is from an avenue of cherry trees that haven't been touched in years. I'm in the process of remedial pruning them all, taking out rubbing and crossing branches, I have noticed they are sparsely leafed. They have had something chewing on the leaves but not significantly.

I'm just thinking they need a good feed??

Could be nitrogen deficiency but given the yellowing is more towards the leaf tip I'd be more inclined to go with magnesium.

Sometimes a graft or rootstock issue. Rootstock can die first starving the scion even in a mature tree.

These are the trees with prominent graft, there's a little bit of strimmer damage but nothing major

Can we see a photo of the 'something chewing' leaves, it may be something more serious Pseudomonas syringae pv morsprunorum shot hole leaves and yellowing leaves together with sparse foliage are all symptoms of it. Remedial pruning may not be the solution .

On all 30 trees, there were not one sign of any bleeding at all, all were totally clear

Dean, is that new tarmac under the trees?

Does rocksalt affect cherrys? Not a tree that grows well on the coast with salty winds. If road got blathered with salt for the first time this winter, there isnt a broad area to wash away is there?

A very good point to consider Goaty
