I have a 50 tree avenue of Bradfored Pears, currently standing about 3 metres high. I run sheep on the farm. About 4 months ago, (during our winter) sheep started to nibble away at the bark, and have almost ringbarked some 15 trees. As they came into leaf, they seems to be OK, but now that we are into high summer, those trees are starting to show sign of high stress.(appear to be turning to autumn colours). Initially I wrapped wet newspaper around the effected areas, and bound it on with garden tape.
Does anyone have any better suggestion as to how I can save these trees?
Hoping someone can assist.
