April in the Mohawk Valley pushes stone up out of the ground — glacial leftovers the frost heaves loose every spring, sitting in the lawn as if someone set them there. Stone Age Landscaping LLC works with that ground around Utica, Marcy and Deerfield, clearing what winter turned up, raking the beds out and getting lawns ready for their first cut. Mowing and trimming carry the summer, while mulch and edging give the beds a defined line. Then the leaves arrive and the season gets put away. Old valley soil asks for patience and pays it back in a good stand of grass.
