Why should I prune my trees?

Pruning is part of the general maintenance of your tree. Dead branches in trees are an access point for diseases and insects which can harm or kill the tree. Dead branches can also fall on people underneath. Crossing branches rub together, creating a wound, which is another potential access point for diseases and insects. Pruning can improve the structure of the tree, making it both more aesthetically pleasing and less likely to fall or break. A well-maintained tree adds value to your property.

What are the various methods to prune trees?

Pruning Types:

• Crown cleaning - Crown cleaning consists of the removal of dead branches of a certain size from the crown of the tree. A typical estimate will read: 'crown cleaning of dead branches 2 inches in diameter and larger'.
• Crown thinning - Crown thinning includes crown cleaning of dead branches. In addition, thinning includes the selective removal of crossing, dying, weak, or diseased branches and water sprouts. The goal is to reduce hazards and increase air movement through the crown of the tree.
• Crown raising/Elevation - Essentially the removal of lower branches of a tree to increase clearance from the ground.
• Crown restoration - Crown restoration pruning improves the structure and appearance of trees which have been severely headed, vandalized or storm damaged.
• Crown reduction - Crown reduction decreases the height and/or spread of a tree. Consideration should be given to the ability of a species to sustain this type of pruning.
