There is a green in Worcester in June that Elm Park wears best, the grass under those old footbridges holding shade like water. BeeZees Lawn & Landscape works toward that green on the ordinary lots around it, mowing, trimming and edging and bracketing the growing year with spring and fall cleanups. A yard on a Worcester side street is rarely flat, so the mowing lines follow the ground the way the streets follow the hills. The pleasure is in the finish: the crisp edge along a walk, the clippings gone, a small rectangle looking cared for. Come October those same lawns get their leaves cleared and one last cut before the ground gives up its warmth.
