North Tulsa runs out into the Osage hills, where the prairie begins and the town's last lawns meet bluestem. Fairway Lawns of Tulsa mows and feeds those lawns across the long green stretch of the year, from the first Bermuda flush in May to the October cuts that come slow and easy. Fertilization and weed control keep the turf even; mowing and edging give it the crisp border that makes a yard look intended. Autumn light out this way is gold on the grass by six o'clock, and it shows every line the mower left behind. That is the part worth getting right.
