By mid-July the monsoon sets a clock over the Front Range: mornings bright and still, thunderheads stacking over the mountains around two, rain that may or may not reach Sherrelwood by four. JIREH LANDSCAPING LLC works that clock — mowing early while the grass is dry, trimming and edging through the good hours, off the lawn before the sky makes up its mind. The yards on these blocks are small and squared, so the work is precise: a clean line at the walk, nothing left ragged at the fence, clippings blown back off the concrete. Cleanups bracket the year at both ends, once when things green up and once when they let go. It's a rhythm you could set a neighborhood by.
