Ground covers are an excellent way to retain moisture in your garden, but they do come with some potential downsides. While they can reduce water evaporation and suppress weeds, certain types of ground covers may attract pests or become invasive. Understanding these drawbacks helps you make informed decisions for your landscaping needs.
What Are the Benefits of Using Ground Covers for Moisture Retention?
Ground covers offer numerous benefits that make them a popular choice in landscaping:
- Moisture Retention: By covering the soil, ground covers reduce water evaporation, helping to keep the soil moist for longer periods.
- Weed Suppression: They act as a natural barrier against weeds, reducing the need for chemical herbicides.
- Erosion Control: Ground covers stabilize the soil, preventing erosion, especially on slopes and hillsides.
- Aesthetic Appeal: They add visual interest and texture to gardens, enhancing the overall landscape design.
What Are the Downsides of Using Ground Covers?
While ground covers have many advantages, there are some downsides to consider:
Can Ground Covers Become Invasive?
Some ground covers can spread aggressively, overtaking other plants in your garden. Species like English ivy and periwinkle are known for their invasive tendencies. It’s essential to choose non-invasive varieties or manage their growth through regular maintenance.
Do Ground Covers Attract Pests?
Certain ground covers may attract pests such as slugs, snails, and rodents. These pests can damage the ground covers themselves or other nearby plants. Selecting pest-resistant varieties and maintaining healthy garden practices can mitigate this risk.
Are There Maintenance Challenges with Ground Covers?
Ground covers require regular upkeep to prevent them from becoming overgrown or unhealthy. This includes:
- Pruning: To keep them within bounds and promote healthy growth.
- Weeding: Despite their weed-suppressing abilities, some weeds may still penetrate the cover.
- Watering: While they help retain moisture, young ground covers need consistent watering until established.
Do Ground Covers Impact Soil Quality?
Some ground covers can deplete soil nutrients, especially if they are heavy feeders. Incorporating organic mulch or compost can help maintain soil health.
How to Choose the Right Ground Cover for Your Garden?
Selecting the appropriate ground cover depends on several factors:
- Climate: Choose varieties suited to your local climate conditions.
- Sun Exposure: Consider whether the area is shaded or receives full sun.
- Soil Type: Some ground covers prefer sandy soils, while others thrive in clay.
- Growth Rate: Opt for a ground cover that matches your maintenance capacity and garden design.

What Are Non-Invasive Ground Covers?
Non-invasive ground covers include options like creeping thyme, sedum, and sweet woodruff. These plants tend to stay within their designated area and are easier to control compared to invasive species.
How Do Ground Covers Help with Erosion Control?
Ground covers stabilize soil with their root systems, which hold the soil in place and reduce the impact of rainwater runoff. This makes them ideal for slopes and areas prone to erosion.
Can Ground Covers Be Used in Vegetable Gardens?
Yes, ground covers can be used in vegetable gardens to suppress weeds and retain moisture. However, choose non-invasive varieties that won’t compete with your vegetables for nutrients and space.
How Often Should Ground Covers Be Watered?
Newly planted ground covers should be watered frequently until they are established. Once mature, they typically require less frequent watering, depending on the climate and soil type.
What Are Some Shade-Tolerant Ground Covers?
Shade-tolerant ground covers include hostas, ferns, and lamium. These plants thrive in low-light conditions and can add greenery to shaded areas of your garden.
