The oaks in Busse Woods stood here long before the subdivisions did, and their descendants still shade half the yards in Elk Grove. Castillo Landscape works under that canopy all summer — mowing turf that gets four hours of sun instead of ten, trimming around trunks and borders, hauling out clippings and deadfall. Shade lawns want a lighter hand and a taller cut, and knowing that is most of what keeps them green into August. There is a quiet pleasure in a shaded yard that still looks kept: mottled light, straight lines, tidy edges against the concrete. By evening the property reads as looked-after, from the curb clear back to the fence.
