PS1.5 Weed Control Fabric

PS1.5 is a good quality, weed control geotextile. Weed control fabrics are formulated to resist ultraviolet light deterioration, and are inert to commonly encountered soil chemicals. The fabric will not rot or mildew, is non-biodegradable, and is resistant to damage from insects and rodents. The design allows for water, air and nutrients to penetrate to the plants roots.

PS1.5 Weed Control Fabric Instructions

  1. Prepare Area

    Remove all weeds from the desired area. For added protection, apply pre- emergent herbicide before laying down fabric.

  2. Place Fabric

    Unroll fabric and cut to desired length. Fit fabric around plants, lights, etc., by cutting slits “X” where needed. Overlapping a minimum of 4-6 inches and secure with SRW Fabric Staples, staggering 1.2 staples per square yard.

  3. Cover Fabric

    Immediately cover with 3-4 inches of mulch, bark, decorative rock or stone to protect fabric from sunlight and to enhance the appearance of your project.

The fabric has a coating on the material to make it roll better. After 24-48 hours, this will break down and the water will go through normally.

Competitive products will add a chemical to improve this water flow initially.  SRW does not add this chemical to keep it clean and free of unwanted materials. This chemical is called a surfactant and is only temporary. Once the fabric is installed and dirt and debris come in contact with the fabric, it reduces the tendency of the fabric to resist absorption. Installation of one side over the other does not have an impact on performance.

If you would like to test the ability of the fabric to allow water to flow through, I would suggest adding a little dish washing soap to the fabric and rub it in.  Dish soap is also a surfactant and this is to show you that the fabric will allow water to flow properly once it is installed.  It is not necessary to add this to the entire application since installation on top of soil will have the same effect once your landscaping is installed over the top.

The primary causes are improper fabric application and sometimes extremely stubborn perennial weeds or grasses. Be sure to follow the recommended fabric application directions to fully cover the entire area. In the rare case of particular weeds actually growing under or through the fabric, a herbicide application may be needed.

Solution: Application of herbicides may be necessary in particular installations. The use of a plant fabric will prevent most weed growth and limit the need for chemicals. (No individual solution will completely eliminate all weeds forever)

Weeds will grow anywhere there is an organic environment present that will allow germination. If wind blows soil and seeds onto the surface of any fabric or mulch covering there is the possibility of weed growth. Mulch itself will eventually break down and create a soil-like environment for weed seed germination.

Solution: Quick application of systemic herbicide and later application of early spring or late fall pre-emergence herbicide. Follow the directions on the label.

While black plastic does stop weeds, it also keeps air and water away from the soil, so plant-killing diseases develop. Landscape fabric blocks weeds, but its permeability allows the proper balance of air, water and nutrients into the soil. As a result, plants can grow up to twice the size of plants grown without fabric.
