Dead wooding is the removal of dead, dying and broken branches from a tree’s canopy. It’s one of the most straightforward things you can do to reduce the risk a mature tree poses to people and property, and in most cases it’s completed in a single visit.
The work is typically specified by minimum branch diameter, for example removing all deadwood over 25mm. Every cut is made at the natural branch collar, with no stubs left behind. Stubs rot back into the tree and create further problems. Done correctly, the tree can compartmentalise each wound and the result lasts several years before the next inspection is needed.
