Needs revival

This is a pic of a tree I've inherited on my patch. I'm lead to believe its a wild cherry tree, but please please correct me if I'm wrong. It's seen all of one, singular cherry like fruit this year and whilst I'd say 85% of the tree looks healthy..the odd leaves look as attached..It's middle of my patch so should be the centre of attention. I'm feeling a bit sad for it what is it and how do I revive please??

 

@Emily Jones
I have a cooking cherry and last year I had 1 single cherry so I feel your pain. It started to look a bit tatty with the odd leaf looking rough. I cut it back by a third and gave it fish blood and bone watered in very well and its grown like mad but Ill have to wait till next year for fruit.

 

If it's a wild cherry don't expect decent fruit, they are usually small and basically bird food.
It could be a decent variety though, not easy to tell until you get fruit.

Just guessing but I think it probably had an aphid attack earlier in the year.
I don't think you can do much about it now.

 

Oh great, i'll try the same and keep my fingers crossed! It would be lovely to see it flourish

 

Oh dear. I'll keep you posted on its progress. I had an aphid attack on the runners this year so it could well be. I'm going to give it a good prune in the autmun and see how we get on. Keep everything crossed for me

 

Prune at your peril
Pruning will produce lots of leafy growth next year.
Leave well alone and you should get more blossom/ fruit.
