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 divots into the soil beneath the divots to hold such divots in place until their edge 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 deter withdrawal of the shanks and lifting of the divots or turf.
