To be effective weed control, there are four things that must be accomplished.
The Master Gardner Landscape Fabrics are designed to reach a determined price point and provide a relative value.
• Effective Weed Control must allow moisture & nutrients to pass freely into the soil- Most professionals now understand the ill effects of using a non-porous membrane. Not only is it bad for the planting area, but also allows runoff of the aggregate on top of it.
• Provide for the escape of CO2 – If the fabric does not breathe properly, a toxic build up in soil can make for a sour and sterile soil.
• Withstand installation stress- The fabric should be strong enough to withstand the vigorous stresses of application, but any added strength typically means a reduction in air and water flow and “paying extra” for something that you do not need.
• Block light- Weeds and grasses grow to the light that comes through even the smallest openings and if you can block the light, weeds cannot germinate beneath. They do not force their way through the barrier, they grow to the light. The proper Spunbond Fabric almost totally eliminates this as they have microscopic openings.
