Smaller limbs that are broken or structurally compromised can be pruned out. When a comprised limb or section of a tree is too large to prune out, it can be preserved by a support system.
Support systems vary by their purpose, but usually they involve installing a cable in the compromised limb back to a structurally sound section of the tree.
Support systems are almost always installed in conjunction with pruning work to reduce the end weight of the limb.
We can design a support system that is appropriate to preserve your trees of value.
