Late summer in Chatsworth is all horizon, beans going gold at the field edges and heat standing over the blacktop until evening. Prinsco, Inc. mows through that heat on a set rotation, cutting high enough that the turf keeps its color when the rain gets stingy. Edges are the finish work, trimmed tight along walks, drives, posts and foundations, then cleared so the line between grass and concrete is unmistakable. Clippings stay on the lawn where they feed it and off the pavement where nobody wants them. It is ordinary, patient work, and it shows every single week.
