Late April in southern Ohio does not ease in so much as arrive, the hillsides going from gray to green in the span of a warm week. American Prime Hydroseed LLC picks up the mowing right there, when the grass is growing faster than anyone can keep up with and every yard in the township needs a first honest cut. The work runs through trimming around posts and foundations, edging the walk lines back to something sharp, and hauling off what winter left in the fence corners. On the river flats the ground stays soft into May, so the route reads the weather as much as the calendar. What stays with a person is standing at the road afterward and seeing a whole yard laid down even, one shade of green from the mailbox to the back hedge.
