Whether tree roots will continue to grow after a tree has been cut down depends on the species. Some tree roots will eventually die because they can no longer get nutrients through photosynthesis. However, other species that reproduce through root sprouts can continue to grow and produce new sprouts for seven years or more. For example, the roots of elms, ficus, and willows tend to regrow aggressively, while the roots of pines, oaks, and maples will typically die. To determine if a root system is still active, look for new sprouts on the old trunk, stump, or any exposed roots.

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.

While trees can grow in the curb strip between the sidewalk and the street, this placement often poses the problem of interfering with overhead power lines. It’s best to consult your local utility provider and tree planting service before transplanting a tree that might grow into power lines. Also, you should never work within 20 feet of a live power line to avoid the risk of electric shock. Tree branches should never touch nearby power lines, so it’s essential to ensure your tree isn’t in danger of growing too close to them.

A tree can split because of high winds, a change in temperature, or from an infestation or tree disease. All of these factors can overlap, making a single cause difficult to pinpoint. While winter storms are some of the most common causes for a tree to split, it can also happen because of termites or rot.
