Neighbour cut beech hedge back hard
My neighbour cut back my lovely thick beech hedge yesterday on her side of it but in my opinion within my property.
I don't want to get into a boundary dispute so I am wondering if her pruning it hard at this time of year is going to damage it??! She probably took approx 30-45% off the total width of it.
Will this cause long term damage to the hedge?
Thanks in advance.
