There is a particular October wind off Lake Ontario that empties the trees along the Erie Canal path in about a week. Stump and Grind LLC works the yards it blows through, mowing while the season lasts, keeping the trim tight around posts and porch steps, and hauling out the leaf and stick litter autumn leaves behind on Rochester lawns. April asks the opposite chore — the first clear-out of a yard that has been under snow since December, and the cut that makes a place look awake again. The service area takes in Rochester and neighboring Henrietta, Chili, Penfield and Webster. Nothing complicated about the work: grass cut, edges sharp, the yard handed back looking looked-after.
