You can use the formula mentioned earlier to calculate the depth of tree roots. Each inch of width of a tree trunk translates to six inches of depth within the root system. Large trees extend anywhere from 2 to 6 feet into the ground, with some magnificent specimens going even deeper.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

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.

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.
