By the middle of June the lawns around Lords Park have gone deep and fast, the kind of green that doubles in a week of Illinois rain. JACOBS LANDSCAPE LLC keeps up with it, mowing on a schedule, trimming the fence lines and the tree rings, sweeping the cuttings off the walk before pulling away. A yard cut clean has a smell to it that stays in the neighborhood all afternoon. Come October the same lawns need the leaves hauled and the beds put down for winter, and that gets done too. It is plain work, and it makes a whole street look looked-after.
