Glaciers left this corner of Michigan in ridges and hollows, so an April lawn in Putnam Township is rarely flat — it rolls, it drains oddly, and it greens on the south slope a week ahead of the north. Irish Oak Innovations LLC reads that ground and cuts to it: mowing across the grade, working the low wet corners by hand, running the walk and drive lines so the shape of the yard is legible again after the thaw. Spring arrives here in pieces, and the first clean cut of the year is what announces it. Setting the height right in April decides a good deal of what June looks like.
