Cabling/bracing are two forms of structural tree support

Installing flexible cables or rigid braces to reduce the chances of failure of defective unions.

When do you cable / brace?

  • There are three major uses of cables and braces 
    • prevention: to reduce the chance of failure on a healthy tree with structural weakness 
      • Example: a specimen bur oak in good condition but having large limbs with "V-crotches"
    • restoration: to prolong the existence of a damaged tree 
      • Example:  a large Mulberry that lost one of its leaders in a storm, leaving the  others suddenly exposed and vulnerable to further damage
    • mitigation: to reduce the hazard potential of a tree 
      • Example: a picturesque multi-stemmed Locust  that towers over a picnic shelter

How is the cabling / bracing done?

  • By certified arborist who is knowledgeable and experienced in this area.
  • There are many important technical aspects to correct cabling and bracing 
    • the strength and material of the hardware
    • the arrangement of the cables (simple, triangle, box) or rods (single, multiple, etc.)
    • the location, type and size of the entries made into the tree
  • "All work and materials shall be in accordance with ANSI, A300 Tree Care Standards (Part 3) -- 2000."
