Coventry Lake holds the June heat well into the evening, and the yards ringing Wangumbaug's shoreline grow fast in that damp warmth. De Leon Landscaping LlC keeps up with them — mowing on a set week, trimming the edges where lawn gives way to sand, walks blown clean so the yard reads finished. Coventry runs from lakefront cottages to long hill roads with barns still standing on them, and every one of those properties asks for a slightly different hand. The reward is the same everywhere: a lawn that looks intentional from the road. Spring cleanups open the season, fall cleanups close it.
