Tree surgeon's trim, treat (fertilise and spray with chemicals) and transplant
trees to encourage their growth. They also remove dead, decaying trees and plant
new trees.
Tree surgery is often performed to improve the health of a tree, to improve its
appearance or for safety reasons. For example, tree roots may be affecting the
foundations of a building, or underground services such as water pipes, or a
tree's branches may be in danger of breaking off and falling, or may be
spreading into a neighbour's property, or rubbing against a building.
When we go to the doctor, they usually identify symptoms that indicate the type
of illness we may be experiencing. A tree surgeon will carry out an initial
inspection for the same reason - to uncover the symptoms of disease, or in the
worse case scenario, to confirm that the tree has died.
Surgeons may carry out an overall visual inspection, a root collar inspection
where they gently pull away the surrounding earth to look at the condition of
the roots; or an aerial inspection, involving climbing the tree (or going up in
a cherry picker) to look for signs of weakness that are not apparent from the
ground.
Some of the techniques used by tree surgeons include trimming, pollarding and
felling. During trimming, surgeons trim away any dead wood or excess branches.
Pollarding is the annual removal of all of the year's previous growth. This
results in the new growth of slender roots and branches.
