Abstract
A turf anchor stake having a flat shank with a pointed lower end and a headed upper end or two flat shanks connected by a crossbar can be driven through turf into the soil beneath the turf to hold such turf in place until the turf root structure knits with surrounding root structure. To facilitate driving of the stakes the lower ends of the shanks are pointed and lateral projections from the lower end portions of the shanks can be provided to deter withdrawal of the shanks and lifting of the turf.
