Ground covers and mulch can be effectively used together in landscaping to create a lush, low-maintenance garden. This combination offers several benefits, including improved soil health, reduced weed growth, and enhanced visual appeal.
What Are Ground Covers and Mulch?
Ground covers are low-growing plants that spread across the soil surface, forming a dense mat. They are ideal for filling in spaces between larger plants and can be used to prevent soil erosion. Common ground covers include creeping thyme, vinca minor, and sedum.
Mulch is a layer of material spread over the soil to retain moisture, suppress weeds, and improve soil quality. It can be organic, such as bark chips or straw, or inorganic, like gravel or landscape fabric.
Benefits of Combining Ground Covers and Mulch
How Do Ground Covers and Mulch Work Together?
- Weed Suppression: Ground covers and mulch both act as barriers to weeds. While mulch prevents sunlight from reaching weed seeds, ground covers compete for nutrients and space.
- Moisture Retention: Mulch helps retain soil moisture by reducing evaporation, while ground covers provide shade, further minimizing moisture loss.
- Soil Health: Organic mulch breaks down over time, enriching the soil with nutrients. Ground covers contribute organic matter through leaf litter.
Why Use Both in Your Garden?
- Aesthetic Appeal: Combining different textures and colors of mulch and ground covers can enhance the visual interest of your garden.
- Erosion Control: On slopes, ground covers hold the soil in place, while mulch reduces the impact of rain, preventing erosion.
- Biodiversity: Using a variety of ground covers and mulches can create a more diverse habitat for beneficial insects and organisms.
Choosing the Right Ground Cover and Mulch
What Factors Should Be Considered?
- Climate: Select ground covers suited to your local climate conditions. For instance, ice plant thrives in dry, sunny areas, while hostas prefer shade.
- Soil Type: Choose mulch that complements your soil. For clay soils, coarse mulch like bark chips improves drainage, while finer mulch suits sandy soils.
- Plant Compatibility: Ensure ground covers won’t outcompete other plants. Low-growing, non-invasive species are ideal for mixed plantings.

Practical Tips for Using Ground Covers with Mulch
How to Effectively Combine Ground Covers and Mulch?
- Prepare the Soil: Remove existing weeds and debris. Amend the soil if necessary to improve drainage and fertility.
- Plant Ground Covers: Space plants according to their growth habits. Allow room for them to spread.
- Apply Mulch: Spread mulch around the base of ground cover plants, leaving a small gap around stems to prevent rot.
- Maintenance: Regularly check for weeds and replenish mulch as needed to maintain effectiveness.
Example: Creating a Low-Maintenance Border
- Select Plants: Use creeping thyme as a fragrant ground cover along pathways.
- Choose Mulch: Apply a layer of bark chips for a natural look and effective moisture retention.
- Combine: Plant thyme in clusters, then surround with mulch to create a defined edge that requires minimal upkeep.
People Also Ask
Can Ground Covers Replace Mulch Altogether?
While ground covers can reduce the need for mulch, they may not fully replace it. Mulch offers specific benefits like immediate weed suppression and moisture retention that ground covers alone might not provide.
What Are the Best Ground Covers for Shady Areas?
Hostas, ferns, and sweet woodruff are excellent choices for shady spots. They thrive in low-light conditions and can be paired with mulch to improve soil health.
How Often Should Mulch Be Replenished?
Organic mulch should be replenished annually or biannually, depending on the rate of decomposition and the thickness of the original layer. Inorganic mulch, like gravel, may not need regular replacement but should be checked for coverage.
Do Ground Covers Attract Pests?
Some ground covers can attract pests, but many, like creeping thyme, have pest-repellent properties. It’s important to choose species that are less prone to pest issues.
What Is the Best Time to Plant Ground Covers?
The best time to plant ground covers is in early spring or fall when temperatures are moderate. This allows plants to establish roots before extreme weather conditions.
Incorporating both ground covers and mulch into your garden design can lead to a thriving, low-maintenance landscape. By understanding the unique benefits and selecting the right combination for your environment, you can enhance both the beauty and functionality of your outdoor space.
