Category Landscape Rock

Landscape rocks are known for being a low-maintenance form of ground cover that works well as a focal point or as an accent for plants and water features. With proper ground preparation, you can expect the decorative rocks to stay in place for many years. Sand is a common base material you can use beneath the landscaping rocks to achieve several goals.

Stabilize Landscaping Rocks

Smaller landscaping pebbles, such as black polished pebbles, can potentially move out of place if they aren’t provided with proper support. Putting down a layer of sand before you add the decorative rocks gives them a way to anchor slightly down into the ground. The sand also provides support that prevents the decorative rocks from sliding around when it rains.

Promote Good Drainage

Many people put down decorative rocks to help with drainage issues on their property. Adding sand to the landscaping design further promotes good drainage. As rain falls, it soaks into the sand, which prevents it from running through your property in little streams. By grading the sand first, you can also direct water runoff to the areas where you prefer it to go.

Make Weed Control Easier

Base layers are also used in landscape designs to prevent weed growth. Landscaping fabric is one option you can use as a barrier to prevent weed seeds from getting to the ground, but that can make it harder to pull the weeds that somehow manage to sprout. With sand, pulling up weeds is easier because the ground is less compacted.

Hide Darker Soil

If you plan on using lighter-colored landscape rocks, such as gold or snow-white pebbles, you may be concerned about having darker soil show through any gaps. Putting down enough decorative rocks to fully cover the soil helps with this problem. But putting down lighter-colored sand can alleviate all of your concerns, since you can often match it to the shade of the decorative rocks you choose.

Save Time & Energy on Creating Rock Gardens

With other base materials, you could find you need to do a large amount of prep work. For instance, landscaping fabric will need to be measured and cut to fit the space perfectly. Concrete requires pouring and waiting for the new surface to cure. With sand, you’ll simply have it poured into place, and you can then begin putting the decorative rocks down immediately after. This provides you with a quicker way to create a beautiful landscaping design that requires minimal maintenance.

Use as a Natural Alternative to Landscaping Plastic

For many years, landscaping plastic was the go-to base layer for river rocks and beach pebbles. However, the use of plastic in landscaping designs might not always be preferable nowadays. If you prefer to only use natural materials on your lawn, sand is an excellent choice. Since sand doesn’t break down over time, you can expect the results of your project to last. Sand is also a safer choice in areas where animal conservation is a priority.

No matter what kind of landscaping project you’re planning, decorative rocks and beach pebbles can give it additional depth, character, and beauty.
