Should I Use Landscape Rock Or Bark?


Rock is more expensive than bark mulch. The price of rock mulch varies, depending on the type and size, but generally costs two to three times more than an application of mulch. But remember, it doesn’t break down and disappear into the soil like bark mulch does. You don’t need to replace it every year.


Many homeowners use bark mulch around plants to help retain moisture, insulate soil from cold and heat, keep weeds away, and minimize erosion. When planning your home’s landscaping, it’s important to consider whether to use rock or an organic mulch like tree bark for groundcover.

Frequently Asked Questions

Is bark better than gravel?

Wood chips naturally decay and will need to be replaced more often than gravel. Also, if they are not properly packed down, bad weather can wipe them away and spread them across your property. Gravel has great longevity and tends to stand up better to the elements, especially strong winds.

Which is better gravel or mulch?

Rocks are better at weed-prevention than mulch and are also lower maintenance. Stones can also add to the aesthetics of a property. However, rock cover is not good for gardens that receive a lot of sun because they retain more heat than mulch. Ultimately, it all comes down to personal preference.

Is it better to use bark mulch or rocks?

Both the weight of the rocks and the weed barrier make it difficult to replant annuals every year, and the rocks will intensify the heat from the Kansas summer sun. Deciding whether to use bark mulch or rocks depends on your landscape design, budget, climate, and the types of plants, trees and shrubs the mulch will go around.

Is it OK to put rocks in garden beds?

Rocks don’t add anything to the soil. So plants that grow in beds mulched with rocks may need extra fertilizing. If your landscape has trees that drop a lot of leaves and debris, rock mulch might not be your best choice, as it accumulates and sticks in the rocks.

Is it OK to use lava rocks in a garden?

Lava rocks supply a durable and attractive choice, but they aren't suitable for all garden areas. Deciding on whether to use lava rocks or an organic mulch, such as bark, in the landscape depends on the types of plants you are growing, the amount of upkeep preferred and your aesthetic preferences.
