Nothing in Rowley looks more hopeful in May than bare ground taking on its first green haze. Dalzell Hydro seeding puts that green down — hydroseeding new lawns and worn patches, then the mowing, trimming and edging that keep them honest once they take hold. Spring and fall cleanups handle whatever the wind along Route 1A leaves behind. From the rise near the town common you can see how the yards and fields stitch together toward the marsh, and every repaired lawn is one more even square in that pattern. Grass is slow and then all at once; the trick is being there for both parts.
