April rain sends Goffle Brook up over its stones and turns every low corner of a Hawthorne yard to sponge. Lawn Solutions LLC times its work to that — waiting out the soft ground, then cutting, edging, trimming and feeding as the grass comes on hard through May. A spring cleanup pulls the winter's litter out of the beds; a fall one takes the leaves before they mat down and smother anything. The right cut height in June is what keeps a lawn from burning off in July. Small decisions, repeated weekly, are the whole of it.
