River-valley ground grows grass the way it grows corn — give it a warm week and two inches of rain and a lawn in Ursa will be over the mower's ears by Friday. Grass masters lawn care works against that clock through the whole green stretch of the year: cutting on a set schedule, trimming in along fence corners and garden beds, blowing the drives and walks clean before the truck pulls out. Late spring is the test, when everything comes at once; late summer is patience, holding height while the heat presses down. Fall brings the leaves off the maples and the long, slow work of putting yards to bed. The whole point is simple — a lawn that never gets ahead of the person mowing it.
