Landscape fabrics are categorized as which type of weed control?

• A. Cultural control
• B. Mechanical control
• C. Chemical control
• D. Biological control

Answer: (A)

This question tests how landscape fabrics suppress weeds by changing the growing environment. They work by acting as a physical barrier that blocks light from reaching the soil, which reduces weed seed germination and the growth of weeds beneath the fabric. This preventative, non-chemical approach falls under cultural weed control, because it changes site conditions to lower weed pressure rather than killing weeds with herbicides, removing them after they appear, or relying on living organisms to suppress them. Landscape fabrics are a classic example of a cultural practice that keeps weeds from establishing in the first place, alongside mulching and smart irrigation management.
