Late summer on the north side of Arlington Heights runs hot and still, sprinklers ticking across ranch-house lawns at dusk, the air barely moving past Camp McDonald Road. Puglia Landscaping keeps the mowing rolling through it, timing cuts so turf is not scalped in the heat and holds its color into September. Trimming and edging follow every mow, squaring off drives, walks and the corners a mower rounds. Spring and fall cleanups take care of the two ends of the season. The aim is simple and visible from the street: an even lawn with a clean line at every edge, week after week.
