Late August, out where West Peabody runs into ponds and woods, the field grass goes to seed and the evening is nothing but crickets. Grasshopper Lawn and Property Services keeps the tamer ground on the other side of the fence in shape — mowing on a regular cycle, trimming and edging, weed control, and the cleanups that come with spring and fall. A lawn cut at the right height holds its color through a dry stretch, and that is a decision, not luck. There is a good feeling in stepping back at the end of a property and seeing every line parallel. Summers on the North Shore are short; the yards should look their best for all of it.
