The ground around Washington is that deep prairie black a county farther out would fight over, and a lawn set on it will answer to feeding the way a field does. Greenkeepers Fertilization Company reads the year in exactly that language: an early application as the frost lets go, weed control while the crabgrass is still thinking about it, and a late feeding that works underground all winter. Mowing, trimming and cleanups fill the weeks in between. Then the calendar turns, the wind comes flat and hard across the section roads, and the same trucks carry plows and salt for driveways, walks and lots. Green in one half of the year and bare pavement in the other — both are the same kind of care.
