Tips for Securing and Installing Landscape Fabric

• Depending on how hard your soil is, separate each 6-inch sod staple between 2-4 ft. For very soft soil, separate each staple by 2 ft. For very hard soil, separate each staple by 4 ft.
• For very soft soil, we recommend longer sod staples, such as 9-inch sod staples.
• For very hard soil, we recommend thicker sod staples, such as 6" x 2" x 6" 9-gauge staples.
• Tools required for landscape staples installation:
• Rubber Mallet
• Gloves

Comparison with Competition

How this staples/fabric calculator works

Staples

Far more staples are required in soft soil than hard soil to properly anchor the landscape fabric in place.

To be precise, in soft soil, install one staple every 1 foot. In normal soil, install one staple every 3 feet. In hard soil, install one staple every 5 feet.

Landscape fabric

The calculator assumes that landscape fabric is being used to cover every square foot of the plot of land.

When rolling out landscape fabric, it's ideal to overlap the edges of the landscape fabric about 12%, so that weeds cannot grow in between the edges of the fabric.

Landscape fabric should not be stretched straight over a dip in the ground.

Rather, the fabric should be touching the ground at all times and should adjust to the contours of the land, such as bumps, dips, and hills.

This allows you to walk on the installed landscape fabric without worrying about damaging it.

FAQ

Is geotextile fabric the same as landscape fabric?

Typically yes. Geotextile simply means strong synthetic fabric which landscape fabrics are. However, some projects require special geotextile fabric with unique specifications such as a specific tensile strength. If you are not sure, simply email us and we can help. 

What can you use instead of landscape fabric?

There are no alternatives. If you are looking for a product to stop weeds or create a separation layer, landscape fabric is your only option.

Can I just put landscape fabric over weeds?

Yes, you can place landscape fabric over existing weeds or on top of weeds

How wide can you buy landscape fabric?

Sandbaggy sells landscape fabric as wide as 17.5 ft.

What size is landscape fabric?

Sandbaggy sells landscape fabric rolls from 3 ft wide up to 17.5 ft wide. Depending on the size of the landscaping area, some choose smaller rolls while others choose wider rolls. This is more just personal preference. A 3 ft wide landscape fabric roll will block weeds just as well as a 10 ft wide landscape fabric.
