How should I properly prune a maple tree to ensure its health and growth?

To properly prune a maple tree for health and growth, start by removing dead or diseased branches. Next, prune any crossing or rubbing branches to prevent damage. Trim back any branches that are growing too close together to allow for better air circulation. Finally, avoid over-pruning and only remove up to 25 of the tree's canopy in a single year to avoid stress.
