Global Syn Turf's artificial turf supplier installed a putting green in my backyard about 3 weeks ago. The putting green allowed me to practice all elements of my short game. The synthetic grass putting green surface features the same putting green Bernard Langer has in his backyard in Florida. The putting green was designed with a 3 foot fringe of short grass around the putting green. The artificial turf putting green lays on a compacted crushed rock aggregate that is shaped to the contour I wanted for my putts. Global Syn Turf provides a wide variety of artificial turf products for all your putting green, fringe and rough surfaces. Their national network of putting green designers are the best. Thanks Global Syn Turf.
