We hired a guy to come and prune 3 trees at the front of the house. I suppose they were about 8 metres high but we want to keep them below the wires for internet, cable etc. None of the branches and limbs were neatly sawn off, they were all just broken and splintered. Obviously the guy didn't have a sharp saw, so it was just easier to break the branches.
My question is, will this cause any kind of detriment to the trees, like allowing diseases to enter etc?
