Preventing ground covers from becoming invasive involves selecting the right plants, maintaining them properly, and implementing control measures. By choosing non-invasive species and practicing regular maintenance, you can enjoy the benefits of ground covers without the risk of them overtaking your garden.
What Are Ground Covers?
Ground covers are low-growing plants that spread across the ground, providing a living mulch that can suppress weeds, reduce soil erosion, and add visual appeal to gardens. They come in a variety of species, including perennials, annuals, and even some shrubs.
Why Do Ground Covers Become Invasive?
Ground covers can become invasive due to their rapid growth and ability to spread via runners, seeds, or rhizomes. Invasive ground covers can outcompete native plants, leading to reduced biodiversity and altering ecosystems.
How to Choose Non-Invasive Ground Covers?
Selecting the right plants is the first step in preventing invasiveness. Consider these factors when choosing ground covers:
- Native Species: Opt for plants that are native to your region, as they are less likely to become invasive.
- Growth Rate: Choose slower-growing species that are easier to manage.
- Reproductive Traits: Avoid plants that produce numerous seeds or spread aggressively through runners.
Here are some non-invasive ground cover options:
| Ground Cover | Type | Ideal Conditions |
|---|---|---|
| Creeping Thyme | Perennial Herb | Full sun, well-drained soil |
| Wild Ginger | Perennial | Shade, moist soil |
| Blue Star Creeper | Perennial | Partial shade, moist soil |
How to Maintain Ground Covers?
Regular maintenance is crucial to keep ground covers in check. Here are some practical tips:
- Regular Pruning: Trim back ground covers to prevent them from spreading beyond their designated area.
- Boundary Barriers: Install physical barriers, such as garden edging, to contain the spread.
- Mulching: Use mulch to suppress the growth of unwanted spreaders.
- Monitoring: Regularly inspect your garden to detect early signs of invasiveness.
How to Control Invasive Ground Covers?
If ground covers start to become invasive, take immediate action to control them:
- Manual Removal: Pull out unwanted plants by hand, ensuring you remove the entire root system.
- Herbicides: Use targeted herbicides for persistent species, but apply carefully to avoid harming desirable plants.
- Smothering: Cover the area with a tarp or thick mulch to starve the plants of light and moisture.

How Do I Stop Ground Covers from Spreading?
To stop ground covers from spreading, regularly prune them and install barriers. Monitoring their growth and promptly addressing any unwanted spread is also essential.
Can Ground Covers Be Used on Slopes?
Yes, ground covers are ideal for slopes as they help prevent soil erosion. Creeping juniper and vinca minor are excellent choices for stabilizing slopes.
Are All Ground Covers Invasive?
Not all ground covers are invasive. Many species, especially native ones, can coexist with other plants without becoming problematic. Always research the growth habits of a plant before introducing it to your garden.
How Often Should I Prune Ground Covers?
Prune ground covers at least once or twice a year, depending on their growth rate. Regular pruning helps maintain their shape and prevents them from overtaking other plants.
Conclusion
Preventing ground covers from becoming invasive requires careful selection, regular maintenance, and proactive control measures.
