Answer: Most gardeners prune the top off their red maples so they will become full and dense and multi-trunked. It sounds as though you want a single trunk that's bare to the crown. You can remove the lower branches (within reason) and then plan on rubbing out anything that sprouts along the trunk. The truth of the matter is, your maple will eventually become a tall tree, whether or not you remove the lower branches. Enjoy your maple!
