By late June the lawns of Tinley Park go deep and dense, the kind of green that holds an evening's light after the sun is down behind the rooftops. ExperiGreen Lawn Care keeps that color honest — mowing on a rhythm the grass can live with, trimming the fencelines and hydrants, feeding turf that has to survive July on flat, sun-struck ground. Ranch homes here sit close to their front yards, so a lawn is the first thing anyone says about a house. A stripe pattern laid across a corner lot is worth the extra pass, and so is the clean line where the blade stops and the mulch bed begins. Around Bettenhausen Park the ballfields set the standard, and a yard on the block ought to answer it.
