By four o'clock near Wyassup the oaks throw long shadows across the yards, and every mown edge stands out sharp against them. B&M Lawn & Garden tends North Stonington's lawns and garden ground at that unhurried country pace, mowing, trimming, and keeping beds and borders in order as the season moves along. A garden in this town is half cultivation and half negotiation with ledge, shade and deer, and the answer is mostly a matter of showing up on schedule. Cut lines stay straight, beds stay clean, and a yard looks cared for long before anyone reaches the front step.
