Below Walden the Wallkill takes a slow bend, and in midsummer the herons stand in it like they have nowhere else to be. CKR Landscaping and Beyond mows the lawns along that river ground, where the soil is rich and the grass grows accordingly — trimming the edges, cutting a clean line at every walk and drive. The season starts with spring cleanup, pulling winter's debris off beds that thaw early in this valley. It ends with leaves, gathered up before the November rains press them into the turf. A yard cut straight and finished at the borders looks right against that river, and it is satisfying every time.
