Ground cover: the unsung hero of many a thriving garden. Often overlooked in favor of showier blooms and towering vegetables, these low-growing plants offer a wealth of benefits, and their presence can transform a garden from a struggling patch to a flourishing ecosystem. But is ground cover right for your garden? This article dives deep into the world of ground cover, exploring its advantages, disadvantages, various types, and how to successfully incorporate it into your landscape.
Understanding Ground Cover: More Than Just a Pretty Face
What exactly is ground cover? Simply put, it’s any plant that spreads horizontally and covers the ground. This broad definition encompasses a vast range of species, from creeping perennials and sprawling shrubs to even some low-growing annuals. The key characteristic is their ability to fill in spaces, forming a dense mat that suppresses weeds and improves soil health.
Ground cover isn’t just about aesthetics, although it certainly adds visual appeal. It serves several critical functions in a garden setting, acting as a living mulch and contributing to a healthier and more sustainable ecosystem.
The Multifaceted Benefits of Ground Cover
There’s a reason why ground cover is increasingly recommended by gardening experts. Its advantages are numerous and far-reaching, impacting everything from weed control to water conservation.
Weed Suppression: Nature’s Weed Barrier
One of the most significant benefits of ground cover is its ability to suppress weed growth. By creating a dense canopy, it blocks sunlight from reaching weed seeds in the soil, preventing them from germinating and competing with your desired plants. This reduces the need for herbicides and manual weeding, saving you time and effort.
A well-established ground cover acts as a natural barrier, outcompeting weeds for resources like water and nutrients. It essentially creates an unfavorable environment for weed seeds to thrive.
Soil Erosion Control: Protecting Your Precious Topsoil
Ground cover plays a vital role in preventing soil erosion, especially on slopes or in areas prone to heavy rainfall. The roots of ground cover plants help to bind the soil together, preventing it from being washed away by water or blown away by wind.
This is particularly important in newly established gardens or in areas where the soil is already degraded. Ground cover can help to stabilize the soil, allowing other plants to establish themselves and thrive.
Moisture Retention: Reducing Water Consumption
Ground cover can help to retain moisture in the soil, reducing the need for frequent watering. The dense foliage of ground cover plants helps to shade the soil, reducing evaporation and keeping the soil cooler. This is especially beneficial in hot, dry climates.
By reducing water loss, ground cover can help you conserve water and lower your water bill. It also creates a more favorable environment for plants, as they are less likely to suffer from drought stress.
Improved Soil Health: A Living Mulch
As ground cover plants decompose, they add organic matter to the soil, improving its structure and fertility. This organic matter helps to improve drainage, aeration, and water-holding capacity of the soil.
Ground cover also provides a habitat for beneficial soil organisms, such as earthworms and microbes, which further contribute to soil health. These organisms help to break down organic matter, releasing nutrients that plants can use.
Aesthetic Appeal: Enhancing Your Garden’s Beauty
Beyond its practical benefits, ground cover can also enhance the aesthetic appeal of your garden. It can add texture, color, and visual interest to otherwise bare areas.
Ground cover can be used to create a variety of effects, from a lush, green carpet to a tapestry of colorful blooms. It can also be used to soften hard edges, fill in gaps between paving stones, and create a more naturalistic look.
Wildlife Habitat: Supporting Biodiversity
Many ground cover plants provide valuable habitat for wildlife, attracting pollinators like bees and butterflies, as well as providing shelter for small animals.
Choosing native ground cover species can further enhance their value to wildlife, as these plants are adapted to the local environment and provide food and shelter for native animals.

What types of ground cover are best suited for shady areas?
Several ground cover options thrive in shady conditions, offering beautiful foliage and suppressing weeds where sunlight is limited. Hostas, with their diverse range of leaf shapes, sizes, and colors, are a classic choice for shade gardens. They provide lush ground cover and require minimal maintenance, adding visual interest to darker areas. Another excellent option is vinca minor (periwinkle), an evergreen ground cover that forms a dense mat of glossy foliage and produces delicate blue flowers in the spring.
For a more textured look, consider ferns such as ostrich ferns or maidenhair ferns, which prefer moist, shady conditions. They provide a delicate and graceful ground cover, creating a woodland-inspired aesthetic. Additionally, sweet woodruff (Galium odoratum) is a fragrant option that spreads easily and produces dainty white flowers, adding a pleasant aroma to your shade garden. Be mindful of the spreading habits of some of these plants to ensure they don’t become invasive.
How do I prepare the soil before planting ground cover?
Proper soil preparation is crucial for the success of your ground cover planting. Start by removing all existing weeds, grass, and debris from the planting area. This can be done manually or with the help of herbicides, but ensure the herbicide is suitable for the specific weeds and won’t harm your desired ground cover plants. Next, loosen the soil to a depth of at least 6-8 inches using a garden fork or tiller, improving aeration and drainage.
Once the soil is loosened, amend it with organic matter such as compost, well-rotted manure, or leaf mold. This will enrich the soil with nutrients, improve its water-holding capacity, and create a favorable environment for root growth. Work the organic matter into the soil thoroughly and level the planting area with a rake. Finally, conduct a soil test to determine the pH level and nutrient content, making any necessary adjustments with lime or fertilizer to ensure optimal conditions for your chosen ground cover species.
How far apart should I space ground cover plants when planting?
The spacing between ground cover plants depends on the specific species and its growth habit. Generally, you should aim for a spacing that allows the plants to fill in the area within a reasonable timeframe, typically one to two growing seasons. Check the plant label or seed packet for specific recommendations, as each variety has different spreading capabilities.
As a general guideline, low-growing, spreading ground covers like creeping thyme or clover can be planted closer together, around 6-12 inches apart. More vigorous ground covers, such as vinca or pachysandra, should be spaced further apart, typically 12-18 inches. Planting too closely can lead to overcrowding, while planting too far apart can result in a sparse and weedy ground cover. Adjust the spacing based on your desired density and the expected growth rate of the particular ground cover variety you are using.
How do I control weeds while my ground cover is establishing itself?
Weed control is essential during the establishment phase of ground cover, as weeds can outcompete the young plants for resources. Start with a thorough pre-planting weed removal process, as described in previous answers. After planting, apply a layer of organic mulch, such as shredded bark, wood chips, or straw, around the ground cover plants. This will help suppress weed seed germination and retain soil moisture.
Regularly monitor the area for any emerging weeds and remove them promptly by hand pulling or using a weeding tool. Avoid using herbicides on young ground cover plants, as they can be sensitive to chemicals. Once the ground cover has filled in and formed a dense mat, it will naturally suppress weed growth, reducing the need for manual weeding. Consistent vigilance during the establishment phase is key to a healthy and weed-free ground cover.
What are some drought-tolerant ground cover options?
For gardens in dry climates or areas with limited water availability, drought-tolerant ground covers are an excellent choice. Sedums, also known as stonecrops, are succulents that store water in their leaves and stems, making them highly drought-resistant. They come in a variety of colors and textures, providing visual interest while requiring minimal watering. Another great option is creeping thyme, a low-growing, fragrant ground cover that tolerates dry conditions and attracts pollinators.
Additionally, lamb’s ear (Stachys byzantina) is a soft and velvety ground cover with silver-gray foliage that thrives in dry, sunny locations. It’s deer-resistant and adds a unique texture to the garden. For a more evergreen option, consider ice plant (Delosperma), which produces vibrant, daisy-like flowers and tolerates extreme drought conditions. Remember to research the specific needs of each plant to ensure it’s well-suited to your local climate and soil conditions.
Are there any ground cover options that are deer-resistant?
Deer can be a significant nuisance in many gardens, and choosing deer-resistant ground covers can help minimize damage. While no plant is completely deer-proof, some varieties are less appealing to deer than others. Consider planting creeping thyme, which has a strong scent that deer tend to avoid. Its low-growing habit also makes it less attractive as a food source.
Another good option is pachysandra, an evergreen ground cover that deer generally leave alone due to its waxy leaves. Additionally, ferns, particularly those with a coarser texture, are often overlooked by deer. Avoid planting ground covers that are known to be deer favorites, such as hostas or English ivy, unless you are prepared to take measures to protect them with fencing or deer repellent.
