Your Urban Forest Arborist will make proper recommendations based on site-specific details, history of any past damage or failure, and tree species and vulnerability to failure. There are different support systems recommended for each different situation that arises.
Cabling – Cables are installed to restrict the distance that branches can move in relation to each other. Installed across a weak junction, they can greatly reduce the risk of failure. Installed on overextended branches, cables can carry some of the load when the branch moves excessively.
Bracing – Brace rods are used to reduce the risk of two or more leaders spreading apart or moving sideways in relation to each other. They are also used to fasten together a union or branch that is split or cracked.
Guying – Established trees are rarely guyed. However, there are a few cases in which installation of guys is appropriate – for example, trees that have been uprighted after being uprooted or blown over and trees with serious anchorage issues (either root defects or soil conditions that compromise anchorage).
Propping – Props are ridge structures installed between the ground and a branch or trunk to provide support from below. Props are used under branches or leaning trunks to keep the branch off the ground or a structure, to maintain clearance, or to reduce the potential for whole-tree failure.
