I have a 10 year old pear tree in the garden and some of the the leaves are coming off it. It blossomed well and has lots of tiny pears developing, but the leaf coverage isn't great. It's better towards the top of the tree.
Rainfall has been non existent recently, could this be contributing to the problem? Also, there are birds bouncing all over it each day as I have bird feeders in it. Some of the birds are crows and magpies, could this be causing a problem?
