On a June evening the Bruce Freeman Rail Trail fills with bikes and strollers, and the lawns along its Westford stretch are at their greenest of the year. Sciuto Property Maintenance LLC keeps those yards on a rhythm: mowed on schedule, trimmed at the fence posts and foundations, blown off so nothing is left on the walk. Spring opens with the rake and the first mulch, and October ends with the leaves gathered before they mat down on the turf. Grass runs fast here in early summer and slows in August, and the visits bend to that. What the neighbors notice is only that the yard always looks like someone was just there.
