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.

Most tree surgeons cost around $100 per hour or between $70 and $200 per hour for their services. You might get flat fees for more straightforward services, like a tree assessment, tree removal, stump grinding, and one-off treatments, but many times, treatments for tree diseases or pests will be charged based on an hourly rate or a per-visit rate. Since the cost of a tree surgeon can vary widely, it’s best to speak with an arborist near you to get an idea of what your particular issue will cost to correct.

Completely topping a plum tree is a risky business. Cut too much, and you’ll kill your tree. That said, you do need to trim the top of your tree to encourage bushy growth, maintain your tree’s vase shape, and limit size. 

A plum tree's central leader (or trunk) should never extend more than 3 feet above the highest branch. When you first plant your tree, cut the central leader so it’s 2 to 3 feet tall. As it grows, cut it back 12 to 20 inches until it reaches its desired height. Never prune more than one-third of the new growth.
