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.

Finding a reliable arborist starts with researching specialists in your area and checking their licensing and certifications. Use online resources like the Better Business Bureau (BBB) to conduct research on each company. Next, contact the arborist and ask the following questions to see whether they are the right fit for your project:

• Do you handle or specialize in dealing with the issue I’m having?

• Are you fully insured?

• Do you have customer references I can call?

• Do you have any third-party certifications?

• What equipment and strategies do you plan to use?

Opt for a barefoot tree. Pros harvest barefoot trees when they’re dormant (leafless). They shake the dirt from the root ball and pack it in moist material. 

These trees can cost half as much as the trees at your local nursery, and you can buy them online—so there’s a much wider selection. Just make sure you keep your barefoot tree cool until you’re ready to plant it.

Deciduous shade trees (the type of trees whose leaves fall off in autumn) need to be pruned in late winter—between February and March. That’s because it’s easier to find and remove sick or dead branches when no leaves are present. And wounds close and heal faster in colder temperatures so pruning them at this time also makes them less prone to infection.
