String Trimmers

A string trimmer can get right up to tree and shrub trunks, fence posts, and concrete steps. But be careful to stop short of hitting these with the string. You can kill a tree by stripping its bark, or cut a chunk out of wood or concrete. Approach these fixtures gingerly, and pull back as soon as you hear or feel the distinctive click of slapping string. (Or better yet, create mulch beds around trees and posts so you never have to get close.)
