July here is humid in a way that has weight to it, so the work starts early, in the long shade a sycamore throws across a front yard at seven. Francisco's Lawn Maintenance LLC moves through the morning cool — mowing, trimming, edging the drive, blowing off the walks — and is well down the street before the heat gets serious. A lawn cut at that hour holds its color, and the smell of it stays in the block for a while afterward. Weekly through the growing months, then leaves and cleanup once the season turns over. Yards throughout Centreville and the nearby Metro East towns are on the list.
