Different Varieties of Natural Landscaping Rocks

Garden rocks are ideal for adding height, texture, and color. They can even be used to create a decorative focal point. Below, you will learn more about the many different kinds of landscape rocks. 

We hope our guide will make it easier for you to choose the best rocks for your garden design.


Choosing the Best Landscaping Rocks

Landscaping rocks can be used for a wide variety of purposes. You can use them as decorative features, as an edging material, or to build walls.

But before you get your heart set on a certain type of landscaping rock, check for availability and cost. The accessibility and size of the stones will greatly impact the cost.

Landscape rocks that are local to your area are usually the most affordable option. To get a quick idea of what types of stones are available in your area, give your local quarry a call.

If you have a small area you are working on, you may be considering small decorative rocks. You can often find these sold in bags at home and garden stores.

If you are interested in using small decorative gravel for a large area, you will have to buy it by the cubic yard from a landscaping supply company.


Roles of the Landscaping Rocks to Your Garden

Are the landscape rocks serving a purpose other than aesthetics? Below are some other reasons for using landscape rocks.

Choosing the Best Landscaping Rocks

Use Landscaping Rocks as Mulch or Ground Cover

Landscape rocks can be used instead of mulch. You can also use the stones to cover unsightly areas or create walking paths. If the stones will be used as a path, look for something small that is easy to walk on.

You do not want them to move around too easily. A good choice is often small, crushed limestone.

Drainage Issues

Do you have an area with drainage issues? You can use garden rocks to create a barrier. Or you can use the stones to make a French drain that will help take care of any wet spots.

Erosion Prevention

If you have an area that is washed out easily, you can use landscape rocks to help slow down the erosion.

Protect Your Plants

Different types of plants require varying amounts of sunlight. For plants that require very little sunlight, you can use decorative rocks to block the sun. 

For plants that require lots of sunlight, you can use rocks to bounce sun onto the plants.

Reduce Weeding

Landscape rocks can reduce the amount of weeding you have to do. An example of this is a limestone driveway. If you have bad weeds, you can use a limestone with dust.

The dust acts as a thin concrete layer when it gets wet and then dries. This will help prevent the weeds from growing.

Durability

Will the garden rocks be walked or driven on? If so, you want a rock that will be able to handle all the wear. Look for stones such as limestone or pavers.


Factors to Consider When Choosing Landscape Rocks

After putting a ton of work into your landscaping project, you want the final results to be perfect. Before you make your final decision on which types of landscape rocks to use, take into consideration:

Factors to Consider When Choosing Landscape Rocks

Garden Rock Appearance

Is it a Focal Point

Are you wanting the landscape rocks to be focal points? If so, you will probably want to purchase large landscaping rocks. If you are wanting the stones to be a ground cover or decorative feature, you will want smaller landscape rocks.

Garden Theme

Does your garden design have a specific theme? Choose the garden rocks that will add to the design. For example, if you have a tropical theme, you can incorporate lava rocks. If you are creating a Zen Garden, you will want river rocks.

Crushed or Smooth Stones

Are you looking for a stone with jagged edges or a smooth surface? Crushed stone will have a rough texture. You can often find crushed limestone used in driveways.

The rough texture can help with traction. Smooth stones on the other hand can roll around when walked or driven on. Smoother stones are often used when you are looking for a crisp, clean look.

Stone Color

Look for a stone color that will complement the overall design of your garden and home. You can even combine different types of stones to create decorative patterns.
