The answer to 'tree overgrown' is that a tree may become overgrown due to lack of regular pruning, improper initial planting, or rapid growth. Symptoms include branches growing excessively long or dense, blocking light and encroaching on structures. Solutions include selective pruning to thin out the tree, removing suckers and water sprouts, and considering a full tree removal if the tree is severely overgrown or poses a safety risk.
For most overgrown trees, homeowners can perform light pruning and maintenance themselves. However, for large or difficult trees, it's best to hire a professional arborist who has the proper equipment and expertise to safely and effectively prune the tree without damaging it.
