Clients often wonder when it is best to use Weed Cloth/Landscape Fabric. It can be a helpful tool when installing your newly designed landscape project. Here are a few key points to consider if it is necessary for your design.

Quality Selection Tips:

  • Choose a non-woven geosynthetic textile fabric.  Do not use plastic!

  • Don’t choose the cheap stuff that will only last a season.

Reasons to Use:

  • Helps to deter weeds from growing up into your beautifully designed landscaping.

  • Acts as a separation barrier for the landscape rock and soil, so the stone doesn’t get pushed down into the soil.

  • Reduces the need for herbicides as weed control.

  • Best for use with landscape rock (inorganic mulch).

  • Allows water absorption into the soil, which helps to keep moisture in the ground for plants.

Installation Tips:

  • Do not use in garden beds where plant movement is frequent.

  • Fabric must be covered with mulch or it will deteriorate with UV exposure. 2”-3” coverage is recommended.

  • Helpful to apply a preemergent to the soil prior to laying the cloth. This aids to inhibit weed growth down through the fabric.

  • Landscape fabric does require some maintenance.

Applications Where it is Not Necessary:

  • Not as necessary for arid/desert climates as it is for wetter regions.

  • Not as necessary when using organic mulch, as it inhibits nutrient transfer into the soil.
