April in Jamestown is a slope full of half-melted snow with green pushing up underneath it, and the hillside yards above the river come back first. Dorler Landscape Designs LLC starts there, clearing the terraces and banks, opening the beds, taking the first cuts while the ground is still soft, then holding mowing, trimming and edging steady all the way to leaf-fall. Hill work asks for its own kind of attention: mow lines that follow the grade, edges that hold their shape, corners that do not scalp. Come winter the pitch matters even more, and those same slopes get plowed, shoveled and salted so a car can come down them without a prayer.
