I finally did a DIY artificial turf practice green in the back yard. This is a silly project that I have wanted to attempt for about 15 years. Fortunately for me, procrastinating for that long ended up with having much better technology in turf to play with. I have about 60 hours in this project and started it on the three hottest days of this summer. So, apparently I am not getting any smarter as I age. Step one was to remove some pool fence and begin excavating with a skidsteer. We later put the fence back in after adding 20 feet more to accommodate some room for the green and some chipping "tee-boxes" that I still have to build. Then I added about 7 inches of road gravel. It was spread two inches at a time and then sprayed down with the garden hose and I ran a plate compactor over each layer. The final layer is crushed 5/8's minus. Then I added some contour with additional crushed fines and broomed them around and compacted. Then, cut in the cups and cemented them in place. Next, stretch the turf over the surface and stretch with a carpet stretcher and use 5 to 6 inch spikes every 4 inches around the outside edge. Then I added chipping turf for fringe and broomed in about 800 pounds of silica sand to provide ballast and create a realistic action to the green. The more sand, the faster the green and it allows the green to accept pitch shots just like the real deal. But, no mowing ever! We have already had a ton of fun on this thing and I look forward to many years of use.
