A wet spring on the North Side turns everything at once — one warm rain and the side streets go from gray to green between a Tuesday and a Thursday. Bamboo Lawn Care meets that surge with a mower deck and a plan: cut on schedule, trim the fence lines, edge the walks, keep bagged clippings from ever reaching the alley. Small city yards grow fast in that first flush and go ragged just as fast when nobody is watching. Here somebody is watching. By June the lawns along the route have that even, close-shorn look that makes a front porch feel like a good place to sit.
