Tree Pruning

Crown Reduction

The most common form of tree pruning is crown reduction. Crown reduction is reducing the size of the entire tree. You may want to use crown reduction in the following situations:

  1. To reduce the weight of potentially dangerous branches.
  2. To balance an uneven tree, for example, following storm damage, or after bad pruning.
  3. To prevent trees obstructing or damaging buildings.
  4. Prevent trees from interfering with overhead telephone and power lines.

Thinning and Dead Wooding

Crown thinning is the selective removal of stems and branches to increase light penetration and air movement throughout the crown of a tree.

Dead wooding is the cutting out of dead branches from the tree for safety purposes.


Pollarding is a pruning system in which the upper branches of a tree are removed, promoting a dense head of foliage and branches. It has been common in Great Britain and Europe since medieval times and is practiced today in urban areas worldwide, primarily to maintain trees at a predetermined height.

It should be noted that some species of trees do not take well to pollarding, e.g. the beech tree.
