I have what I thought was a healthy copper beech tree about 18years old and 20ft high in full leaf.
I have noticed cracks in the bark and on peeling the dead bark back have found wood lice infesting the space between the bark and the trunk.
What is going on and what can I do about it? I also have problems with any sort of plants as wood lice just munch their way through everything except hardy shrubs.
Any help gratefully received
