Preventing ground covers from invading your lawn is essential for maintaining a tidy and healthy garden. By implementing strategic planting and maintenance techniques, you can effectively manage ground covers and keep them from spreading where they’re not wanted.
What Are Ground Covers and Why Do They Spread?
Ground covers are low-growing plants used to cover soil in gardens and landscapes. They are popular for their ability to suppress weeds, reduce soil erosion, and add aesthetic appeal. However, their vigorous growth can lead to unwanted spread into lawns.
Why Do Ground Covers Spread?
- Aggressive Growth: Many ground covers, like English ivy and creeping jenny, are designed to spread quickly.
- Rhizomes and Stolons: These underground stems allow plants to spread horizontally.
- Seed Dispersal: Some ground covers propagate through seeds that can easily spread into surrounding areas.
How to Prevent Ground Covers from Spreading Into Your Lawn
1. Choose the Right Ground Cover
Selecting the right type of ground cover is the first step in preventing unwanted spread. Opt for non-invasive species that are less likely to encroach on your lawn. Consider plants like:
- Pachysandra
- Vinca minor
- Ajuga
2. Use Physical Barriers
Installing physical barriers is an effective way to contain ground covers. Here are some options:
- Edging Materials: Use metal, plastic, or stone edging around the perimeter of the ground cover area.
- Root Barriers: Install underground barriers to prevent rhizomes from spreading.
3. Regular Maintenance
Consistent maintenance is crucial to control the spread of ground covers:
- Pruning: Regularly trim back ground covers to keep them within designated boundaries.
- Mowing: Mow the edges of your lawn where ground covers meet to prevent encroachment.
4. Mulching
Applying mulch around the borders of ground covers can help suppress their spread by:
- Blocking Light: Prevents ground covers from growing beyond their intended area.
- Improving Soil Health: Enhances soil quality, making it less conducive for invasive growth.
5. Chemical Control
In some cases, chemical control may be necessary:
- Herbicides: Use selective herbicides to target ground covers without harming your lawn. Always follow label instructions carefully.
Practical Example: Managing Creeping Jenny
Creeping jenny is a popular ground cover known for its vibrant foliage but can quickly overtake a lawn. Here’s how to manage it:
- Install Barriers: Use landscape fabric and edging to contain its spread.
- Regular Pruning: Trim back runners monthly.
- Spot Treatment: Use a selective herbicide on any shoots encroaching into the lawn.

How Do I Remove Ground Covers That Have Already Spread?
To remove ground covers that have already spread, start by manually pulling or digging them out, ensuring you remove all roots. For persistent plants, consider using a targeted herbicide and replant with grass seed to restore the lawn.
Can I Use Vinegar to Control Ground Covers?
Vinegar can be used as a natural herbicide to control ground covers, especially on small areas. Apply it directly to the plants, but be cautious as it can also harm grass and other nearby plants.
What Are Some Non-Invasive Ground Covers?
Non-invasive ground covers include sweet woodruff, wild ginger, and lamb’s ear. These plants typically grow slowly and are less likely to spread aggressively into lawns.
How Often Should I Prune Ground Covers?
Prune ground covers at least once a month during the growing season to maintain their shape and prevent them from spreading into unwanted areas.
Are There Any Ground Covers Safe for Lawns?
Yes, some ground covers like clover and creeping thyme can be integrated into lawns as they are less aggressive and can coexist with grass.
Conclusion
Preventing ground covers from spreading into your lawn requires a combination of strategic planting, physical barriers, and regular maintenance. By choosing the right plants and employing effective control methods, you can enjoy the benefits of ground covers without compromising the health and appearance of your lawn.
