Around Washington Park the dooryards are small, the iron fences are old, and a lawn measured in feet still deserves an exact edge. Blade & Bloom brings that kind of attention to the brownstone blocks and to the wider yards beyond them: mowing, trimming, edging along stone and step, with cleanups in spring and again when the leaves come down. Troy's evening light slants low between the rowhouses in July, and a freshly cut strip of green catches all of it. Small ground, finished properly, has a grandeur of its own. That is the standard on every stop.
