I have ten two year old hawthorne shrubs in my back garden in a row distanced approx 3.5 feet apart, they have been growing really well until recently. I have noticed all the leaves have gone crispy and dead and on closer inspection i have found that the base of the (trunk) has been stripped of the bark - it looks as though someone has attacked them with a small penknife! from about 2-3 inches up to the base in a downwards motion. there do not appear to be gnawwing marks it really does appear as though a knife has been used - any ideas? my back garden is enclosed so only my neighbours could possibly have access to it.
