Up on Normandy Heights the lawns roll out from behind low stone walls, and in late August the light crosses them long and gold around seven in the evening. Curb Appeal Design LLC keeps that grass cut, edged and trimmed straight through the Morristown growing season, when heat and thunderstorms trade places week to week. An edge along a curb, cut once and then kept, changes how an entire front yard reads from the street — that is the part of this work worth slowing down for. Beds get cleaned and mulched in spring, turf gets its leaves pulled off in fall, and the mowing height rises through the dry weeks so the lawn holds its color. A house looks like itself when the ground around it is in order.
