Ground covers can effectively suppress weeds by creating a dense mat that blocks sunlight, but fertilization can enhance their growth and weed-suppressing abilities. Fertilization provides the nutrients necessary for vigorous growth, helping ground covers establish quickly and outcompete weeds.
Do Ground Covers Need Fertilization to Suppress Weeds?
Why Fertilization Matters for Ground Covers
Ground covers are low-growing plants that spread quickly to cover the soil. They are often used in landscaping to suppress weeds, reduce erosion, and add aesthetic appeal. While these plants can naturally suppress weeds by shading the soil, fertilization can significantly improve their effectiveness. By providing essential nutrients, fertilization encourages lush growth, allowing ground covers to form a dense canopy that weeds struggle to penetrate.
How to Fertilize Ground Covers for Optimal Growth
To ensure your ground covers effectively suppress weeds, consider the following fertilization tips:
- Select the Right Fertilizer: Use a balanced, slow-release fertilizer that provides nitrogen, phosphorus, and potassium. Organic options like compost or well-rotted manure can also be beneficial.
- Timing: Fertilize in early spring when plants begin to grow actively. A second application in mid-summer can support continued growth.
- Application Method: Spread the fertilizer evenly over the area, following the manufacturer’s instructions. Water the area thoroughly after applying to help nutrients reach the roots.
Best Ground Covers for Weed Suppression
Some ground covers are particularly effective at suppressing weeds due to their rapid growth and dense foliage. Here are a few popular options:
- Creeping Thyme: A fragrant, low-maintenance option that thrives in sunny spots.
- Ajuga (Bugleweed): Known for its vibrant foliage and ability to thrive in shade.
- Vinca Minor (Periwinkle): Offers evergreen foliage and adaptability to various conditions.
- Pachysandra: Ideal for shady areas, forming a thick, weed-resistant carpet.
Practical Example: Using Creeping Thyme
Creeping thyme is an excellent example of a ground cover that benefits from fertilization. In a case study, a garden plot planted with creeping thyme and fertilized with a balanced, slow-release fertilizer showed a 30% increase in coverage compared to an unfertilized plot. This enhanced coverage significantly reduced weed emergence, demonstrating the value of fertilization in weed suppression.

What Are the Benefits of Using Ground Covers?
Ground covers offer several benefits beyond weed suppression. They help retain soil moisture, reduce erosion, and provide habitat for beneficial insects. Additionally, they can add texture and color to your landscape, enhancing its visual appeal.
Can Ground Covers Replace Mulch?
Yes, ground covers can serve as a living mulch, providing many of the same benefits. They protect the soil, retain moisture, and suppress weeds. Unlike traditional mulch, ground covers also contribute to the landscape’s aesthetic value and require less frequent replacement.
How Long Does It Take for Ground Covers to Establish?
The time it takes for ground covers to establish depends on the species and growing conditions. Most ground covers take one to two growing seasons to fully establish. Fertilization can speed up this process by promoting faster growth and denser coverage.
Are There Any Ground Covers That Don’t Require Fertilization?
While all plants benefit from some level of fertilization, certain ground covers like sedums and native grasses are more tolerant of poor soil conditions and may require less frequent fertilization. These options are ideal for low-maintenance landscapes.
How Do I Choose the Right Ground Cover for My Landscape?
Consider factors such as sunlight, soil type, and climate when selecting a ground cover. For sunny areas, options like creeping thyme and sedum thrive, while shade-loving plants like ajuga and pachysandra are better suited for less sunny spots. Consult with a local nursery for recommendations tailored to your specific conditions.
Conclusion
Fertilizing ground covers is a practical step to enhance their ability to suppress weeds effectively. By providing the necessary nutrients, you encourage robust growth, allowing these plants to form a dense mat that outcompetes weeds. Whether you choose creeping thyme for a sunny garden or ajuga for a shady spot, fertilization can help you achieve a beautiful, low-maintenance landscape.
