Hi
Can anyone tell me what might be the problem with my pear tree.
It’s only been in a few months but already it’s not looking happy. I am new to fruit trees previously only growing vegetables. I have attached pictures plus what I have used.
Any help gratefully appreciated.
Thanks

Could it possibly be pear blister mite?
