April in Plymouth is a negotiation: sixty degrees on Tuesday, frost on the windshield Thursday, and the grass trying to decide whether to believe any of it. Growing Greener Lawns works that hesitant stretch — the first clean cut of the year, trimming and edging back to a real line, fertilizer to push color, weed control before the dandelions claim the whole block. By June the lawns hold a deep, even green that makes an entire street look looked-after. Mowing carries on right through the heat, and the fall cleanup puts the yard to bed under the maples. It is lawn care only, done attentively, from thaw to leaf-drop.
