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.

Only trim palm trees as needed, which is usually about once per year. However, don't stick to that schedule if the palm tree doesn't need it. Avoid trimming palm trees when possible. It’s best to trim palm trees only when you notice a buildup of dead fronds. That said, leave the brown fronds during the dormant season because this organic matter helps protect the tree from the cooler weather.

Pruning trees during the summer can be a bad idea because the new growth will take place during the hottest months of the year, which can stress your tree out. Similarly, pruning during the early fall can be a bad idea, too, because you’d be stimulating new growth when most trees are aiming to go dormant. 

Pruning recommendations will vary by the type of tree, but generally, waiting until winter to prune your trees is a good idea.

The best way is to start controlling tree height long before it grows too large, via careful pruning through the years. But that’s not always possible. If a tree has become too high or too large, use selective pruning to remove the most troublesome branches, one by one, without topping the tree. Gently shaping a tree like this can, over time, correct problems. You can also find growth inhibitors to spray on a tree to stop it from growing too rapidly, but use these sparingly if at all.
