April in Hingham is a slow green rumor — the marsh grass at Home Meadows goes first, then the lawns, one warm week at a time. Pungitore Irrigation & Fertilizer meets that turn head-on with feeding programs, seeding into thin ground, and the mowing and trimming that begin the moment the soil firms up. A lawn fed early and cut often in spring carries itself through July, and that is the reason for the early work. Beds get cleared out, borders get re-drawn, and the debris of winter leaves in a truck. By Memorial Day the yards up toward Cushing Pond look like they were never asleep.
