Here are the tree pruning don'ts according to master arborist, Dave Leonard. Items in parentheses are my comments either from notes or experience.
1) Don't prune trees like shrubs.
2) Don't leave ragged cuts or stubs.
3) Don't use hedge shears for general pruning.
4) Don't prune with sprung, dull or improper tools.
5) Don't prune more than 25%-33% of live wood in a season. (Leaves are the factories that create food for tree so it reduces its food potential which can overly stress tree if pruned too much.)
6) Don't make flush cuts. (make them at limb collar instead)
7) Don't expect pruning to compensate for defects caused by overcrowding, poor soil conditions, improper plant selection, etc. (in other words, do your research and pick the correct tree for the soil type and space that you have available)
8) Don't assume that every good gardener is a good pruner. Check out casual advice before you prune.
9) Don't climb trees! The hazards far outweigh the benefits. Call a Certified Arborist. (Being a do-it-yourselfer I would like to add to this by saying if you climb trees make sure you know what you are doing and use proper safety equipment and techniques.)
