Hiring an arborist or tree surgeon is usually more expensive than a standard tree company, but it is often worth the investment. Arborists have education and certifications that standard companies typically lack, leading to a more professional, expert-level service. Their expertise is particularly valuable for diseased or infested trees, as they can ensure safer removal and help prevent the issue from spreading. Additionally, arborists may be necessary for work near power lines, as uncertified companies are often not permitted to service these trees. If your goal is to preserve the health of your trees, an arborist is the best choice. Their services, such as stump grinding, are also performed with greater expertise to ensure a safe depth that won't cause your lawn to collapse over time.

You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.

How often and long you should water a tree depends on the species and if it is mature or newly planted. The amount of water is also based on the tree's size. A good rule of thumb is approximately 5 gallons per inch of the trunk's diameter.

Adjusting watering to the recommended suggestions for the tree type and weather conditions is vital. For instance, watering trees during a drought is necessary, and you may need to water more frequently than usual.

Horticulturist is a broad term for any type of plant and soil expert. An arborist, meanwhile, specializes in all aspects of tree care. You should hire an arborist when you need assistance with tree-related tasks, such as pruning large trees, removing trees, diagnosing a sick tree, or emergency tree services. Horticulturists aren’t qualified to handle those types of tasks.
