I have a dual fruit apple tree at my allotment.
Last year I had apples from both the eater and cooking apples.
This year only two fruits have set.
On some of the leaves are red spots (which I presume is spider mite) and have treated the tree with an organic mite killer.
Now some of the new leaf tips seem to be curling.
Has anyone any ideas on what is happening.
My pear tree is having similar problems?
