Late August can turn a Swampscott lawn to straw even a block from the water, and the green that comes back in September is one of the better sights in town. Phoenix Lawn Sprinkler Services works those yards — mowing, edging, trimming and seasonal cleanups on a set rotation, from the slope of Jackson Park down to the shore streets. Grass that gets consistent attention holds its color longer and comes back faster once the heat finally breaks. Fall means leaves off and a final low cut; spring means clearing the winter grit and starting the schedule again. Swampscott and the neighboring towns ride the same weekly loop.
