In June the marine layer slides over the Elsinore hills before sunrise and sits on Menifee until mid-morning, and for a few hours every yard is soft and gray and cool. That is the good window for work: The Only Way Landscaping runs mowers and hedge shears while the light is still kind, so the lawn is cut, the shrubs are shaped and the trimmings are gone by the time the sky burns off blue. Seasonal cleanups clear the dry stuff that collects along fences and under the oleanders through a long inland summer. Bed edges get redrawn by hand until the border between grass and mulch is one crisp curve. Around Quail Valley and Sun City, a yard that looks composed on an ordinary Tuesday is the entire point of the job.
