What's wrong with our apple tree?
We have a big old apple tree in our garden that has always been healthy and given us big cooking apples but it has what looks like a serious problem.
We noticed two years ago that some of the bark was coming away and underneath were tiny, rice-like grains (look like bugs of some sort). There are some wood-worm looking holes in some areas too.
Last year a few tiny apples grew and fell quickly.
This year the tree blossomed a bit but we have no apples and the few leaves that came out are shrivelling and turning yellow and brown.
The bark on the lower half has been a rusty colour for a while too, not sure if that's anything to do with it.
I have searched some apple tree problems but can't find anything that matches ours, hopefully someone will recognise it?
