© Roy Boak Tree Service 2011 In certain situations when additional support is desired, (such as often happens in overburdened or multi trunk trees) The installation of steel cables between the branches, in conjunction with proper weight reduction trimming can often reduce the stress on weak or overburdened attachment points thus increasing the safety of your tree.  To insure that this work is performed correctly and that this is a worthwhile procedure.  Please allow our certified arborist to evaluate your particular situation.
