How to Keep Grass from Growing in My Decomposed Granite

Decomposed granite, also known as DG, is a popular choice for landscaping because it is durable, low-maintenance, and versatile. However, one downside of DG is that it can be difficult to keep grass from growing in it. Here are a few tips to help you prevent grass from taking over your DG:

Install a weed barrier: Before you add DG to your yard, install a weed barrier. This will help to block out sunlight and prevent seeds from germinating. You can use a commercial weed barrier or you can make your own by laying down several layers of newspaper or cardboard.

Maintain your DG: DG can hold moisture more effectively than lawn soil, resulting in an environment rich in moisture for a longer period of time. Aeration through top dressing regularly with decomposed granite also prevents new seedlings from sprouting.

Use a pre-emergent herbicide: A pre-emergent herbicide can be applied to DG to prevent seeds from germinating. Be sure to use a product that is safe for use around plants and follow the directions on the label carefully.

Hand-pull any grass that does grow: If you do see grass growing in your DG, pull it out by hand as soon as possible. This will prevent it from spreading and producing seeds.

Avoid mowing your lawn too short: If you mow your lawn too short, it will encourage the grass to spread into the DG. Keep your grass at a height of 3 inches or longer.

Consider using artificial grass: If you are having trouble keeping grass from growing in your DG, you may want to consider using artificial grass. Artificial grass is a great alternative to natural grass and it does not require any maintenance.

By following these tips, you can help to keep grass from growing in your decomposed granite and enjoy a beautiful, low-maintenance landscape.
