Generally, you’ll want to prune back the trunk by 1 to 2 feet each year to promote bushy growth. Doing so concentrates vegetative buds closer to the bottom of the tree, where you can easily harvest fruit. For side shoots that are a year old, leave at least six leaves. 

Never remove more than 30% of a tree’s foliage during pruning—even if your tree is really overgrown. Removing this much foliage at a time could kill your tree.

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.

A pro can guide you on the alternatives to tree topping depending on the specific issues within your trees. For example, if you’re dealing with breakage and cracks in your tree, they may suggest canopy reduction, which removes less than 25% of the tree’s limbs. If you’re dealing with lesser damage, some intentional pruning may be all you need. If you’re looking to get a clearer view through your tree, the pro may also try windowing or skirting your tree.
