April rain turns the brick on Liberty and Grand a deeper red, and the small front lawns behind those iron fences green up almost overnight. Rivera's Landscaping tends the dooryard grass of Newburgh's hill blocks, mowing, string-trimming and edging plots a rider could never turn around in, then clearing a winter's worth of grit off the walks. City grass is close work: hand-tight against the stoop, along the fence line, around the meter, and it either looks cared for or it plainly doesn't. Done right, a strip of lawn twenty feet wide can lift the mood of an entire block. That is the part worth taking time over.
