Choosing the right ground cover can transform your garden, filling in unsightly bare spots, suppressing weeds, and adding a touch of beauty. But with so many options available, finding the fastest spreading variety can feel overwhelming. This comprehensive guide explores some of the quickest growing ground covers, their characteristics, and factors to consider before planting.
Understanding Ground Cover and Its Benefits
Ground cover refers to plants that grow low to the ground and spread horizontally. They act as a living mulch, offering numerous advantages over traditional landscaping methods.
Why Choose Ground Cover?
Ground cover excels at weed suppression. By creating a dense mat, it deprives weed seeds of sunlight and space to germinate. This significantly reduces the need for herbicides and manual weeding, saving you time and effort.
Soil erosion is another significant concern for gardeners. Ground cover helps prevent erosion by binding the soil together with its roots, especially on slopes and hillsides.
Ground cover plants contribute to soil health. As they decompose, they add organic matter to the soil, improving its structure, fertility, and water retention.
Many ground cover varieties offer aesthetic appeal, adding texture, color, and visual interest to your landscape. From flowering options to evergreen foliage, there’s a ground cover to suit every style.
Ground cover can reduce lawn maintenance. Replacing traditional grass with ground cover in certain areas can eliminate the need for mowing, fertilizing, and watering, leading to significant cost savings.
Fast-Spreading Ground Cover Options
Several ground cover plants are known for their rapid growth and ability to quickly fill in large areas. However, “fastest” is relative and depends on factors like climate, soil conditions, and sunlight exposure. Here are some of the top contenders:
Vinca Minor (Periwinkle)
Vinca minor, also known as periwinkle or creeping myrtle, is a popular choice for its vigorous growth and evergreen foliage. It features small, glossy leaves and delicate blue or purple flowers in spring.
Ideal conditions: Vinca minor thrives in partial shade to full shade and well-drained soil. It is relatively low-maintenance and tolerant of dry conditions once established.

Factors Influencing Ground Cover Growth Rate
While certain ground covers are inherently faster-spreading than others, several factors can influence their growth rate. Understanding these factors can help you create optimal conditions for your chosen ground cover to thrive.
Climate and Hardiness Zone
The climate and hardiness zone of your region play a crucial role in determining the growth rate of ground cover. Plants that are well-suited to your climate will generally grow faster and more vigorously.
Soil Conditions
The quality and composition of your soil can significantly impact ground cover growth. Most ground covers prefer well-drained soil that is rich in organic matter. Soil testing can help identify any nutrient deficiencies or pH imbalances that need to be addressed.
Sunlight Exposure
The amount of sunlight that your ground cover receives can also influence its growth rate. Some ground covers, such as creeping thyme and sedum, require full sun to thrive, while others, such as vinca minor and lamium maculatum, prefer partial to full shade.
Watering and Fertilization
Adequate watering and fertilization are essential for healthy ground cover growth. Newly planted ground cover should be watered regularly until it is established. After that, most ground covers are relatively drought-tolerant. Fertilizing with a balanced fertilizer in the spring can help promote vigorous growth.
Planting Density
The density at which you plant your ground cover can also affect how quickly it fills in. Planting more closely together will result in faster coverage, but it can also increase the risk of overcrowding and disease.
Tips for Establishing Ground Cover Quickly
Follow these tips to give your ground cover the best possible start and encourage rapid growth:
Prepare the Soil Properly
Before planting, remove any weeds, rocks, and debris from the planting area. Amend the soil with compost or other organic matter to improve its drainage and fertility.
Choose the Right Planting Time
The best time to plant ground cover is typically in the spring or fall, when temperatures are mild and there is adequate moisture. Avoid planting during the hottest or coldest months of the year.
Water Thoroughly After Planting
After planting, water the ground cover thoroughly to help it establish roots. Continue to water regularly until the plants are well-established.
Apply Mulch
Applying a layer of mulch around the ground cover can help retain moisture, suppress weeds, and regulate soil temperature.
Fertilize Regularly
Fertilizing with a balanced fertilizer in the spring can help promote vigorous growth and fill-in quickly.
Control Weeds
Controlling weeds is essential for preventing competition with your ground cover. Hand-pull weeds regularly or use a pre-emergent herbicide to prevent weed seeds from germinating.
Choosing the Right Ground Cover for Your Needs
Selecting the right ground cover involves considering your specific needs and preferences. Evaluate the following factors:
-
Sunlight: Does the area receive full sun, partial shade, or full shade?
-
Soil Type: Is the soil well-drained, sandy, clay, or rocky?
-
Foot Traffic: Will the area experience heavy, moderate, or light foot traffic?
-
Maintenance: How much time and effort are you willing to invest in maintaining the ground cover?
-
Aesthetics: What type of foliage, flowers, and texture do you prefer?
-
Invasiveness: How concerned are you about the ground cover spreading aggressively?
Consider these aspects to narrow down your options and select a ground cover that will thrive in your landscape. While speed of coverage is important, ensure the selected ground cover is appropriate for the long-term health and balance of your garden. Remember to research specific cultivars within each species, as growth habits can vary greatly.
What factors influence how quickly a ground cover spreads?
The speed at which a ground cover spreads is influenced by several key factors. First and foremost, the species of plant plays a significant role, as some are naturally more aggressive growers than others. Environmental conditions such as sunlight, soil type, and moisture levels are also crucial. A plant thriving in its ideal environment will naturally spread more quickly than one struggling in suboptimal conditions.
Additionally, planting density directly impacts spread rate. Closer spacing encourages quicker coverage by allowing plants to intertwine and fill gaps sooner. The overall health and vigor of the plant also matters; healthy, well-nourished plants will establish and expand their territory more rapidly than those weakened by pests, diseases, or nutrient deficiencies. Finally, pruning and maintenance, such as removing dead or damaged foliage, can encourage new growth and contribute to faster spreading.
Which ground covers are considered invasive and should be planted with caution?
Several ground covers, while visually appealing and fast-spreading, are considered invasive in many regions. English Ivy (Hedera helix) is a classic example, known for its aggressive climbing and spreading habits that can smother native plants and damage structures. Similarly, Japanese Honeysuckle (Lonicera japonica) is highly invasive, quickly overtaking gardens and natural areas, displacing native vegetation and disrupting ecosystems.
Another example is Wintercreeper (Euonymus fortunei), which forms dense mats that outcompete native ground flora. These ground covers, although effective at covering ground quickly, can cause significant ecological damage and require diligent monitoring and control to prevent them from spreading beyond their intended boundaries. Always research local invasive species lists before planting any new ground cover.
How can I control the spread of aggressive ground covers?
Controlling the spread of aggressive ground covers requires a multi-faceted approach. Physical barriers, such as edging or buried retaining walls, can be effective in containing the plant’s roots and preventing it from encroaching on unwanted areas. Regular pruning and trimming are also essential to remove runners and prevent seed production, thereby limiting its ability to propagate beyond the designated space.
Chemical control, using herbicides specifically formulated for the target ground cover, can be employed, but should be done cautiously and according to the manufacturer’s instructions to minimize harm to other plants and the environment. Alternatively, manual removal, although labor-intensive, is a more environmentally friendly option for smaller infestations. Consistent monitoring and prompt action are crucial to prevent aggressive ground covers from becoming unmanageable.
What are some fast-spreading ground covers that are also drought-tolerant?
Several fast-spreading ground covers are well-suited for dry climates due to their drought tolerance. Creeping Thyme (Thymus serpyllum) is a low-growing option that releases a pleasant fragrance when stepped on and thrives in well-drained soil with minimal watering. Sedum species, such as Sedum spurium (Dragon’s Blood Sedum), are another excellent choice, offering colorful foliage and a high tolerance for drought conditions.
Another drought-tolerant option is Silver Ponyfoot (Dichondra argentea), a cascading plant with silver, kidney-shaped leaves that spreads quickly and requires little maintenance once established. These ground covers provide attractive ground cover while minimizing water usage, making them ideal for xeriscaping and water-wise gardening.
How do I prepare the soil for planting fast-spreading ground cover?
Proper soil preparation is crucial for establishing a healthy and rapidly spreading ground cover. Begin by clearing the area of any existing weeds, grass, or debris. Loosen the soil to a depth of at least 6 inches using a tiller or garden fork to improve drainage and aeration. This will allow the roots of the ground cover to penetrate the soil easily and establish themselves quickly.
Next, amend the soil with organic matter such as compost, well-rotted manure, or peat moss to improve its fertility and water-holding capacity. This is especially important if the soil is sandy or clayey. Incorporate a slow-release fertilizer according to the manufacturer’s instructions to provide essential nutrients for initial growth. Finally, level the soil surface and rake it smooth to create an even planting bed.
What is the best time of year to plant fast-spreading ground cover?
The best time of year to plant fast-spreading ground cover generally depends on your local climate and the specific type of plant. In regions with mild winters, fall planting is often ideal, as it allows the plants to establish roots before the heat of summer. This gives them a head start and enables them to spread more quickly in the spring. Spring planting is also a good option, especially in areas with colder winters.
Avoid planting during the hottest and driest months of summer, as the plants may struggle to establish themselves and survive the stress of high temperatures and lack of moisture. Similarly, avoid planting too late in the fall in regions with harsh winters, as the plants may not have enough time to develop a strong root system before the ground freezes. Proper timing is key to ensuring successful establishment and rapid spreading of your chosen ground cover.
Are there any fast-spreading ground covers that are shade-tolerant?
Yes, there are several fast-spreading ground covers that thrive in shady conditions. Pachysandra terminalis is a popular choice, known for its dense evergreen foliage and ability to quickly cover large areas in shade. It prefers moist, well-drained soil and tolerates deep shade, making it ideal for planting under trees or on north-facing slopes. Another shade-tolerant option is Vinca minor (Periwinkle), which features glossy green leaves and delicate blue flowers.
Additionally, Wild Ginger (Asarum canadense) is a native ground cover that spreads readily in shady woodland environments. It offers heart-shaped leaves and prefers rich, moist soil. These shade-tolerant ground covers provide attractive coverage in areas where other plants may struggle to grow, adding visual interest and helping to suppress weeds.
