Building a Putting Green: Preparing Your Backyard
Before you start building your backyard green, you first choose where your green will be and start preparing that space. A space of about 1,000 square feet is preferred as this will give you enough room to practice putting from a variety of distances. It is also important that the space does not contain any steep slopes. Once your field is selected, you will need to dig the entire green area approximately 10 inches deep. This will allow you to add base material that will help with drainage before laying the sod.
Once you've dug out the area that will be your backyard green, the next step is to edge the green with a rim or baffle to keep your perimeter clean. From there, you should be ready to lay your base material. Crushed gravel is recommended, which provides drainage to keep the space from flooding, while also serving as a base for artificial grass.
