By May the Williamsburg waterfront is green again and every backyard between Grand Street and the bridge is waiting its turn. Diyarza Landscaping – Garden Center brings the mowers out for that turn — lawns cut and edged, weeds pulled out of the borders, hedges tightened along the fences. Plenty of these yards are small and boxed in by brick, which only makes an even cut and a clean line more visible. Walk past Domino Park on the way home and the grass there is doing the same thing on a bigger stage. Yard maintenance and mowing across Brooklyn.
