Yes, it is essential to confirm that any tree service company you hire is properly insured before they begin work. Tree removal, trimming, and pruning are dangerous jobs, and proper insurance protects you, your home, and the company from liability in case of accidents or damage. Look for a company that carries both general liability and workers’ compensation insurance, and do not hire one that cannot provide proof of coverage. When browsing for professionals, you can look for indicators like an “Angi Approved” badge, which signifies that the business meets standards like holding applicable licenses and passing a background check. Keep in mind that a license is a legal requirement to operate, while certifications are typically voluntary.

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.

In nature, there are many things that can cause a tree to die, including diseases, insects, and natural disasters such as fires or droughts. Non-natural methods of killing a tree include herbicides or manual intervention, such as cutting it down. Consult a tree removal professional about your options for naturally killing a tree.

You should prune ornamental trees once every other year after the fruit has matured and begun to drop. You should also prune out dead branches whenever you see them. Pruning too often can stimulate more growth, especially in faster growing varieties like Bradford pears.
