The shepherd’s tree, native to the Kalahari Desert in Africa, holds the record for the deepest known tree roots at over 230 feet deep. Some African communities refer to it as the “Tree of Life” since it provides food, shade, and medicinal properties to the surrounding community.

Tree roots are hearty and complex systems, so they don’t die immediately after the rest of the tree is removed. If you leave the root system in place, it takes anywhere from two to seven years for it to run out of nutrients. It is worth noting, however, that the roots stop growing and expanding after cutting down the rest of the tree.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

In the short term, you’ll have a lot of fallen trees to deal with. Tree removal services costs typically start at $200 per tree and increase based on species and size. Then, you’ll have to deal with the loss of trees: That means a loss of shade and a greater risk of rain runoff and erosion. Also, you’ll miss out on the health and aesthetic benefits of having trees on your property, which could even affect the resale value of your home.

That being said, cutting down a tree it’s not always a bad idea. Trees growing too close to rooftops can present fire hazards or debris problems. You may need to remove diseased or dying trees to prevent future issues.
