In late June the thunderheads build up in the west over open country and take their time getting here, and everything green grows an inch while they do. Marshall Lawn Care works Luverne through that season — mowing on a rhythm, trimming close around posts and tree trunks, cutting the edge along concrete, and raking the yard out in spring and again when the leaves let go. Grass in this soil will take whatever the weather hands it and ask for more, so the only real answer is showing up. A yard done right holds its stripes for days and makes a house look like somebody loves it. That is the whole ambition, repeated every week until the first hard frost.
