Living ground covers can indeed act as natural weed barriers, offering an eco-friendly solution to maintaining a healthy garden. These plants not only suppress weeds by covering bare soil but also enhance garden aesthetics and contribute to biodiversity. This guide explores how ground covers work, the best types to use, and practical tips for implementation.
How Do Living Ground Covers Suppress Weeds?
Living ground covers suppress weeds primarily by occupying space and resources that weeds would otherwise use. By forming dense mats, they block sunlight, which is essential for weed germination and growth. Additionally, their root systems compete with weeds for water and nutrients, further inhibiting weed development.
Benefits of Using Ground Covers
- Weed Suppression: Dense foliage prevents sunlight from reaching weed seeds.
- Soil Protection: Reduces soil erosion and maintains moisture.
- Biodiversity: Supports beneficial insects and pollinators.
- Aesthetic Appeal: Adds texture and color to landscapes.
Best Ground Covers for Weed Control
Choosing the right ground cover depends on your climate, soil type, and garden design. Here are some popular options:
| Ground Cover | Sunlight Needs | Soil Type | Growth Rate |
|---|---|---|---|
| Creeping Thyme | Full sun | Well-drained | Moderate |
| Ajuga (Bugleweed) | Partial shade | Moist, well-drained | Fast |
| Sedum | Full sun | Dry, well-drained | Slow |
| Vinca Minor (Periwinkle) | Shade | Moist, well-drained | Fast |
Creeping Thyme
Creeping Thyme is a fragrant, low-growing plant ideal for sunny areas. It forms a dense mat, perfect for suppressing weeds and is drought-tolerant once established.
Ajuga (Bugleweed)
Ajuga thrives in partial shade and moist soil, making it suitable for under trees or in shaded borders. It spreads quickly, providing effective weed control.
Sedum
Sedum is a succulent that prefers dry, well-drained soil and full sun. Its slow growth rate makes it less aggressive, but it’s excellent for rock gardens.
Vinca Minor (Periwinkle)
Vinca Minor is a robust choice for shaded areas. It grows rapidly and can cover large areas, effectively preventing weed growth.
How to Plant and Maintain Ground Covers
Proper planting and maintenance are crucial for ground covers to thrive and suppress weeds effectively.
Planting Tips
- Prepare the Soil: Remove existing weeds and loosen the soil.
- Spacing: Plant ground covers according to their growth habits. Dense planting ensures quicker coverage.
- Watering: Water thoroughly after planting and maintain moisture until established.
Maintenance Tips
- Pruning: Trim ground covers to prevent them from becoming invasive.
- Fertilization: Use a balanced fertilizer in early spring to boost growth.
- Weed Monitoring: Regularly check for and remove any weeds that manage to grow.

What are the advantages of using living ground covers?
Living ground covers offer several benefits, including natural weed suppression, soil erosion prevention, and enhanced garden aesthetics. They also support biodiversity by providing habitat for beneficial insects.
Can ground covers replace mulch?
While ground covers can reduce the need for mulch, they might not completely replace it. Mulch is still beneficial for moisture retention and temperature regulation, especially in newly established areas.
How long do ground covers take to establish?
The establishment time varies by species. Fast-growing ground covers like Ajuga can establish in one season, while slower-growing types like Sedum may take a year or more.
Are ground covers suitable for all climates?
Most ground covers are adaptable, but it’s essential to choose species suited to your specific climate and soil conditions for optimal growth and weed suppression.
Can ground covers become invasive?
Some ground covers, like Vinca Minor, can become invasive if not managed properly. Regular pruning and monitoring can prevent them from spreading uncontrollably.
