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.

The best time to cut down a tree is during its dormant season, typically in winter or early spring, after all the leaves have fallen. Removing a tree during this period is advantageous for several reasons. Frozen ground helps secure the tree stump, protects the surrounding landscape from damage, and reduces the risk of the tree falling in an unintended direction. With the leaves gone, there is less risk of the tree's foliage getting tangled with other trees. Additionally, since this is often a slower season for tree services, you may be able to hire a professional at a lower rate. This dormant period is also the best time for tree trimming.

Yes, tree roots can regenerate after they’re pruned or cut. In fact, trimming can stimulate new growth, especially in healthy trees. The tree’s roots can still grow back even after a tree is cut down, (and learning how to get rid of regrowing tree roots is a separate feat). Still, if you don’t wish to harm a tree, pruning the roots should be done with extreme care, and ideally by a professional.

Not every arborist climbs trees, but most will do so if that’s the best method for assessing or treating a tree. Arborists have a variety of tree climbing gear and safety equipment to choose from when climbing trees. Consult your local arborist about their tree-climbing plan if your service requires that type of task.
