Your back is about to really thank me for this tip! Plus, if your buddies are going to be helping you build your own putting green, then they will be thanking you when you do this...so you owe me. Hey, I'll settle for you dropping me a comment to this post and a picture of how great your new backyard green turned out.
Here it is and it's so simple.
Hire a landscape contractor or landscaper to dig the area and remove the dirt before you and your buddies do the rest of the project. See...that is the back-breaking part of the whole DIY putting green project...the digging out of the area where your green is going to be.
Depending on the size of your golf green, this may be as little as $300...make sure to get 2 or 3 estimates as prices vary, but the time and labor this will save you outweighs that small amount by many times! Plus, it still proves cost-effective if you look at the overall DIY project as opposed to hiring a putting green professional.
For example, If you have a green that is 12 x 20 and you have to dig out 240 square feet of area, say 6 to 8 inches deep, that is a big job for a DIY project...and time consuming.
I practice what I preach , so to speak, because I followed my own advice and hired a landscape contractor to dig my backyard putting green area out before I finished the project myself...best money I ever spent.
Take a serious look at doing this with your backyard DIY putting green project...and make sure to let me know how it all turned out. I may even use your green as a case study online in Residential Putting Green Magazine!
