Ontwa Township sits where the cornfields of Cass County run down to the lakes, Eagle Lake glinting through the trees and the section roads laid straight across the flat. Lawns out here have room to spread, and BW Fertilizing LLC feeds them for it: fertilizer on schedule, weed control through the growing season, turf carried thick enough to handle a July that comes in warm and wet. A lake-country lawn is half yard and half shoreline path, and both wear the same green. The satisfaction is watching a place fill in until the mower leaves one unbroken color behind it. That happens a few weeks at a time, on purpose.
