The answer to 'how often to tree removal' is that there is no single recommended frequency, as it depends on the specific tree, its condition, and the homeowner's needs and goals. Generally, healthy trees may only need to be removed every 10-20 years or more, while trees that are diseased, damaged, or posing a safety risk may require more frequent removal.
Regular inspections by a certified arborist can help homeowners determine the ideal timing for tree removal. They can assess the tree's health, growth patterns, and potential risks, and provide guidance on whether removal is necessary and when it should be done. Factors like the tree's size, location, and impact on the landscape should also be considered when deciding if and when to remove a tree.
