Preventing ground covers from becoming invasive involves selecting the right plants, maintaining them properly, and implementing effective control measures. By choosing non-invasive species and monitoring their growth, you can enjoy the benefits of ground covers without them overtaking your garden.
What Are Ground Covers and Why Do They Become Invasive?
Ground covers are low-growing plants used to cover soil, suppress weeds, and reduce erosion. They can become invasive when they spread rapidly, outcompeting other plants and disrupting ecosystems. This often happens when ground covers have aggressive growth habits, lack natural predators, or are planted in unsuitable environments.
How to Choose Non-Invasive Ground Covers?
Selecting non-invasive ground covers is the first step in preventing them from spreading uncontrollably. Consider the following tips:
- Research Plant Species: Choose native or well-behaved non-native species known for their controlled growth.
- Check Local Recommendations: Consult local extension services or gardening clubs for advice on non-invasive options.
- Assess Growth Habits: Opt for plants with clumping rather than spreading growth habits.
Examples of non-invasive ground covers include:
- Creeping Thyme: Ideal for sunny areas with well-drained soil.
- Wild Ginger: A shade-loving plant that forms dense mats.
- Barrenwort: Offers colorful foliage and thrives in partial shade.
How to Maintain Ground Covers to Prevent Invasiveness?
Proper maintenance is crucial in controlling ground cover spread. Implement these practices:
- Regular Pruning: Trim back ground covers to keep them within their designated area.
- Edging: Install physical barriers like metal or plastic edging to contain root spread.
- Mulching: Apply mulch around the edges to suppress unwanted growth and seed spread.
- Monitoring Growth: Regularly check for signs of spreading and act quickly to remove overreaching plants.
What Control Measures Can You Use for Invasive Ground Covers?
If ground covers become invasive, consider these control measures:
- Manual Removal: Hand-pull or dig out plants, ensuring you remove all roots to prevent regrowth.
- Herbicides: Use targeted herbicides as a last resort, following all safety guidelines to minimize environmental impact.
- Solarization: Cover the area with clear plastic to trap heat and kill invasive plants.
- Competition: Plant taller or more competitive plants to overshadow and limit ground cover growth.

How Do You Stop Ground Covers from Spreading?
To stop ground covers from spreading, use physical barriers like edging, regularly prune plants, and apply mulch. These methods help contain growth and prevent plants from encroaching on other areas.
What Are the Best Non-Invasive Ground Covers for Shade?
Some of the best non-invasive ground covers for shade include wild ginger, barrenwort, and foamflower. These plants thrive in low-light conditions and are known for their controlled growth.
Can Ground Covers Be Used for Erosion Control?
Yes, ground covers are excellent for erosion control. They stabilize soil with their root systems, reducing runoff and preventing soil loss. Choose species suited to your climate and soil conditions for best results.
How Often Should You Prune Ground Covers?
Prune ground covers at least once or twice a year, depending on their growth rate. Regular pruning helps maintain their shape, encourages healthy growth, and prevents them from becoming invasive.
What Are Some Alternatives to Ground Covers?
Alternatives to ground covers include using mulch, decorative gravel, or low-growing shrubs. These options can provide similar benefits without the risk of invasiveness.
Conclusion
Preventing ground covers from becoming invasive requires careful selection, regular maintenance, and effective control measures. By choosing non-invasive species and implementing strategies like pruning and edging, you can enjoy the benefits of ground covers without the hassle of invasiveness.
