Synthetic Turf Putting Green Installation Ideas. (1) Location: The Putting green location is very important during planning. It should be set in as level an area as possible.  The Green should be in an open area away from trees and leaf foliage. If considering lights close to electric service. (2) Size: The Putting Green size can depend on if carpet seams will be used. Most standard rolled carpet has a maximum width. Our local carpet stores have twelve foot maximum width. (Check with your local carpet dealers) (3) Lumber: We used 6x6 pressure treated outdoor wood for the frame of the green. Most lumber comes in two foot multiples 8',10',12',16',18',20' and longer. You will also need galvanized tie plates to hold the 6x6's together and can be found at local hardware stores. We made a simple step up to the green with 2x10 and 2x4 frame out of treated wood and painted the 6x6 and step up for appearance. (4) Green Fill: After the 6x6 are placed and tied together you need to clear any vegetation. No 2 B gravel was then put down about 1 ½" - 2" for the base. Next a vapor barrier was put down on top of the gravel. Next we put down about 3 inches of sand. The sand was dampened with water and raked smooth and some mounding was done for undulations in the green. We also raked up the edges to build up a slope on the edge so that the balls return after contacting the 6x6. (5) Carpet: The synthetic carpet was then put down over the sand and trimmed where needed. To handle the seam we used duct tape with the adhesive facing up and added exterior glue to the tape and pressed the two seams together on top of the duct tape. We purchased the best out door carpet we could find locally. Many of the carpet stores have various qualities to choose from. After allowing the seams to bond we next rolled the green surface with a roller to compress and compact and allowed the green to settle for a few days before putting the cups in. (6) Holes: You can either use medal or plastic practice green cups 4 ¼" depth. Determine the location of where you want the cups and use a marker to trace around the cup on the carpet. Using scissors carefully cut out the hole. Use a small hand shovel to dig out the hole. The cup should be about 1" below the green surface. You may want to dab some glue around the hole cut out to prevent fraying. The 4 ¼" cups will also work with regular flagsticks if needed but 6" cups are even better if you plan on using regular flagsticks often. (7) Hardware: We carry both Pole & Flag type green markers and also the handle pull markers. (see photos below) You may also want to consider cup covers to keep holes free of debris. (8) Comments: We really enjoy our backyard putting green. The synthetic carpet has lasted for four years and still looks great. Your local landscaper can assist on installation of the green if you prefer not to do it yourself. We also purchased a tarp to cover the green in the winter and used standard bricks to hold the tarp down. Our 18' x 18' Putting green was less then $1500 installed complete. There is virtually no maintenance with this synthetic green.
