Midsummer at Silver Lake, the water sits perfectly still and the heat is already stacked under the trees by ten in the morning. Estudillo Landscaping Corp. is halfway through the route by then — mowing, edging, string trimming, hedge and shrub work, mulching, cleanups — moving through Castleton Corners, Sunnyside and Silver Lake before the day gets serious about itself. July grass wants a higher blade and a sharp one, and a lawn cut that way holds its color through a dry week. Every yard ends the same good way: the blower run along the curb, the concrete bare, the green edge sharp against it. Then the truck rolls to the next one.
