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

To 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. Avoid cutting more than 25 of the tree's canopy in one season to prevent stress. Prune during the tree's dormant season for best results.
