There are 4 different types of tree pruning
CROWN REDUCTION & SHAPING – Reducing the overall crown of the tree whilst maintaining or creating the shape of the tree.
CROWN THINNING – Removing branches within the crown without reducing the size or the shape of the tree. This method of pruning is used to increase light penetration and reduce wind resistance.
CROWN CLEANING – The removal of dead, diseased or weak branches. Epicormic shoots can also be removed.
CROWN RAISING – Lower branches are removed to reduce hazards near walkways and roads, to prune back from buildings and to increase visibility for example pruning back from signs.
