Tree pruning is very important and has several benefits but if it is done incorrectly, it can harm a tree. So here is a guide to proper tree pruning: 

Start with a visual inspection, beginning from the top of the tree and then downward.

• Use The 1/3 and 1/4 Rules of tree pruning. 
  

• Do not prune off more than one fourth of the tree's crown in one season.

• Main side branch must be at least one third smaller than the trunk's diameter.

• For most deciduous trees, do not prune up starting from the bottom any more than one third of the total height of the tree. 

• If possible, encourage side branches which form angles that are one third off vertical that form 2 o'clock or 10 o'clock angles with the main trunk.

• For almost all species, the tree must have one trunk. Know which could be the best leader before you start pruning and remove damaged parts prior to pruning for form.

• Do not worry about protecting the pruning cuts. To make pruned trees more visually appealing, you can paint big wounds. However, it does not prevent or minimize decay.

• Keep your pruning tools sharp. When pruning young trees, it is best to use one-hand pruning shears with curved blades.

• Use a pole pruner for higher branches. A major tree pruning project must be done by certified arborist.
