Bolting trees is a technique used by arborists to help add structural support to a failing, or defective union within a tree. A lot of the time trees will just be removed once a dodgy union is discovered (super annoying for me when its not necessary). Some of the time this is the only option. BUT. A lot of the time the tree can be pruned, bolted and SAFELY RETAINED. A great option for trees of high significance.
