Ground staples are metal or plastic stakes used to secure landscape fabric, plastic mulch, artificial turf, and decorative ground materials, helping keep landscaping and gardening installations stable and firmly in place. These U-shaped garden stakes prevent materials from shifting due to wind, rain, foot traffic, or uneven terrain.
Landscape staples are widely used in gardens, greenhouses, nurseries, orchards, and landscaping projects. They are especially important for securing woven weed barrier fabric and weed mat, ensuring the fabric stays tightly attached to the soil for better long-term weed control performance.
Galvanized landscape stakes are commonly preferred for outdoor applications because they provide better rust resistance and longer service life in wet or humid environments.
Many people may be unsure about how to choose the right type, material, and size of garden staples, as well as how to install them correctly for different soil conditions and landscaping applications. In the following sections, we will explain the different types of ground staples, recommended sizes, and proper installation methods in detail to help you select the best option for your project.
Before learning how to install ground staples, it’s important to understand the different materials and designs available, as each type performs differently depending on soil conditions, fabric thickness, and application scenarios.

| 2.2 mm | 3–4 cm | 10 cm | Thin landscape fabric and hard soil |
| 2.5 mm | 3–4 cm | 15 cm | Standard weed barrier fabric installation |
| 2.8 mm | 4 cm | 20 cm | Soft soil and windy areas |
| 3.0 mm | 4 cm | 20 cm | Heavy-duty landscaping and artificial turf |
metal staples are suitable for compact soil and lightweight landscape fabric.
15 cm ground staples are the most commonly used size for general weed barrier fabric applications.
20 cm heavy-duty staples provide stronger holding power in soft soil, sandy ground, or high-wind areas.
Galvanized steel landscape10 cm pins are recommended for outdoor use because they offer better rust resistance and longer service life in wet or humid environments.
In many landscaping applications, ground staples are also used together with plastic or washers (caps). These washers help distribute pressure over a larger surface area, prevent the fabric from tearing, and improve fixation strength, especially when securing weed barrier fabric, plastic mulch, or lightweight ground covers.

10 cm plastic stakes are suitable for lightweight ground cover materials and compact soil conditions.
16 cm plastic garden stakes are commonly used for weed barrier fabric and drip irrigation tubing installation.
20 cm plastic stakes provide improved stability in soft or sandy soil.
When choosing the right ground staple size, longer staples are generally recommended for soft soil, thicker materials, slopes, or windy areas to ensure better anchoring performance and long-term stability.
The number of ground staples needed depends on the size of the landscape fabric, soil condition, weather exposure, and the type of application. Proper staple spacing helps keep weed barrier fabric securely attached to the ground and prevents lifting caused by wind, rain, or foot traffic.
For most landscape fabric installations, ground staples are typically placed every 30–45 cm (12–18 inches) along the edges and seams of the fabric.

Using more staples in high-stress areas helps improve long-term stability and prevents the landscape fabric from shifting over time.
The recommended quantity of landscape staples also depends on the roll size and installation spacing.
| Landscape Fabric Roll Size | Recommended Ground Staples |
|---|---|
| 1 m × 50 m roll | 80–120 staples |
| 1.5 m × 50 m roll | 100–150 staples |
| 2 m × 50 m roll | 150–200 staples |
| Large commercial rolls | According to installation area and spacing |
For standard garden projects, using approximately 2–4 ground staples per square meter is generally recommended.
If the soil is loose, the weather is windy, or the fabric is installed on slopes, additional heavy-duty landscape staples may be required for better anchoring performance.
Installing ground staples correctly helps keep weed barrier fabric secure and prevents movement caused by wind or foot traffic.
Remove weeds, stones, and sharp objects, then level the soil surface before laying the landscape fabric.
Roll out the weed barrier fabric and overlap the seams by approximately 10–15 cm for better coverage.
Insert ground staples through the fabric into the soil every 30–45 cm along edges and seams.
Add extra landscape staples at corners, overlaps, and windy areas to improve stability.
Make sure the fabric is flat and tightly secured to the ground before adding mulch, gravel, or decorative materials.
Galvanized and standard steel landscape pins differ mainly in corrosion resistance, durability, and application environments. Galvanized ground staples are coated with a protective zinc layer, which helps prevent rust and makes them suitable for long-term outdoor use. They are widely used in landscape fabric, weed barrier fabric, artificial turf, and other gardening or agricultural applications where exposure to moisture and weather conditions is expected.
Standard steel ground staples, on the other hand, do not have any protective coating. They are more economical but are more likely to rust when exposed to rain, humidity, or soil moisture. For this reason, they are generally recommended for temporary installations or short-term projects in dry environments.
In general, galvanized landscape pins are the preferred choice for most outdoor landscaping applications due to their longer service life and better weather resistance, while plain steel staples are better suited for cost-sensitive or temporary uses.
Choosing the best ground staples for weed barrier fabric depends on soil conditions, fabric thickness, and installation environment. For most landscaping projects, galvanized steel ground staples are considered the best option because they provide strong holding power and long-term rust resistance in outdoor conditions.
For standard weed barrier fabric installation, 15 cm galvanized U-shaped staples with a 2.5 mm wire diameter are the most commonly used choice. They offer a good balance between strength and ease of installation, making them suitable for general garden beds, landscaping areas, and agricultural applications.
In soft soil, sandy ground, or windy environments, longer and thicker staples such as 20 cm heavy-duty galvanized staples (2.8–3.0 mm wire diameter) are recommended to ensure better anchoring performance and prevent the fabric from lifting over time.
For lighter-duty or temporary projects, plain steel staples or plastic ground stakes can also be used, but they may not provide the same long-term stability as galvanized options.
In addition, using ground staples together with proper spacing (typically 30–45 cm apart) helps improve fixation and ensures the weed barrier fabric remains flat and secure over time.
Using ground staples incorrectly can reduce the effectiveness of landscape fabric and lead to poor stability over time. One common mistake is placing staples too far apart, which allows the fabric to lift or shift in windy or rainy conditions. For most applications, spacing should be adjusted according to soil type and project needs.
Another mistake is choosing staples that are too short for soft or sandy soil. In these conditions, shorter staples may not provide enough holding power, causing the fabric to loosen over time. It is also important to avoid using plain steel staples in long-term outdoor projects, as they can rust and weaken quickly.
In addition, many users forget to reinforce edges, seams, and corners, which are the most vulnerable areas for movement. Proper installation should always include extra staples in these key positions to ensure long-term stability.
For most landscape fabric installations, 15 cm galvanized ground staples are the most commonly used size. Soft soil or windy areas may require longer staples for better stability.
Ground staples are typically placed every 30–45 cm along edges and seams. In soft soil or windy conditions, spacing should be reduced to 20–30 cm.
Yes. Galvanized ground staples are more resistant to rust and are better suited for long-term outdoor use, while plain steel staples are mainly used for temporary or indoor applications.
Yes, ground staples can usually be reused if they are not bent or heavily corroded. However, reuse depends on soil condition and removal care.
For standard installations, 2–4 pieces per square meter are generally recommended. More staples may be needed for slopes, soft soil, or high-wind areas.
