By September the crowds thin and the shingled cottages of Ocean Park get their quiet back, hedges throwing long shadows across grass that has finally gone green again after August. Colonial Landscape LLC works those weeks carefully — mowing, trimming, edging along the walkways, and a fall cleanup that lifts leaves and needles off the turf before frost pins them down. Lawns in Old Orchard Beach take a beating from sun, sand and salt wind, so maintenance here is patient, week-after-week work. Mulch goes into beds that have thinned, borders find their shape, and the clean division between grass and garden returns. Come October the yards look settled and ready to sleep.
