String trimmer

String trimmers are suppose to make trimming fast and easy. Unfortunately, they often kill plants when used improperly. They remove bark from trees. Tall fescue is best cut no shorter than 2 inches and higher is better. The grass around this tree is less than an half inch. The grass will use up its food storage attempting to replace the leaf blade. Thinning and death of the grass will be the result from this practice. The appearance is bad enough of an uneven lawn. This was professionally cut grass. Someone was paid to hurt the grass and tree.
