On a January morning the flatwoods south of Moultrie run gray and clear, and you can hear a chainsaw from a mile off across the peanut ground. SKYHIGH Tree Services spends that cold stretch doing the work trees appreciate most — pruning while the sap is down, pulling deadwood out of old pecans, opening a crown so the growing season has somewhere to go. Removals get planned backward from where the tree has to land: the fence here, the well house there, the pine coming down in lengths a man can carry. Nothing about it is hurried, and nothing gets left behind. When wind off the Ochlockonee bottoms puts a tree on the ground where it has no business being, they undo it limb by limb until the yard is just a yard again.
