Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

A dead tree should always be cut down, because it could fall and cause injuries or damage, and it can also attract insects like carpenter ants. A tree that’s diseased beyond repair should also be cut down, but it’s not always easy for a homeowner to tell. Signs of disease include dying branches, a hollow trunk, leaning, and discolored or missing leaves, but your best bet is to hire a local arborist who can evaluate the tree and tell you if it can be saved or should be cut down.

Aside from removing dead or diseased branches, you should prune your trees somewhere between every one and three years. Some people—particularly commercial farmers—prune their apple trees yearly to produce higher yields. This is the best way to promote tree health. That said, the average homeowner can get away with hard-pruning their mature apple tree every other year or every three years. 

After a big storm, you may not be sure if a tree was struck or not. Look for the telltale long scars, like strips or gouges in the bark of the tree, running in sometimes jagged lines down the length of the trunk. These scars will often show vulnerable living wood inside the tree. It’s also common to see scorched or wilted leaves on the side or top of the tree where lightning struck.
