Which material is commonly used as a barrier between rock mulch and soil to suppress weeds?

• A. Landscape fabric
• B. Plastic sheeting
• C. Newspaper
• D. Weed barrier fabric

Answer: (D)

Using a physical barrier under rock mulch relies on blocking light to prevent weed germination while still letting water and air move through. Weed barrier fabric is designed for this purpose: it’s a permeable textile placed between the soil and the rock that suppresses weeds by reducing light and root penetration, yet allows drainage. It tends to be durable and long-lasting under stones, unlike newspaper that breaks down quickly and plastic sheeting that can trap moisture and hinder drainage. Landscape fabric and weed barrier fabric are both designed to reduce weed growth, but the term weed barrier fabric specifically conveys the purpose of creating an effective, lasting barrier under mulch.
