In June, the lawns around Congress Park hold their green the way the springs hold their cold — steadily, and without much fuss. Allgreen Landscaping keeps that same green going on the streets nearby, mowing on a rhythm and edging along walks until the line between grass and stone is a single crisp stroke. Trimming closes what the mower cannot reach, and cleanups clear the winter's litter in spring and the maples' surrender in fall. There is a particular satisfaction in the last pass of the day, when the stripes line up, the clippings are gone, and the yard simply looks cared for. Saratoga Springs summers are short and bright, and this is how you spend them well.
