What is a typical benefit of a living mulch compared with conventional mulch?

• A. It dries the soil faster
• B. It never competes with crops for water
• C. It suppresses weeds and improves soil health while providing ground cover
• D. It is cheaper in all cases

Answer: (C)

Using a living mulch means growing a ground-cover plant that stays in place to cover the soil. Its main benefit is that it naturally reduces weeds and supports soil health while providing ongoing ground cover. The dense plant cover blocks light from reaching weed seeds, limiting germination, and the living roots and decaying biomass feed soil biology and improve soil structure. Over time this adds organic matter, helps with moisture retention, and reduces erosion, creating a more resilient growing environment.

This isn’t a universal guarantee of lower costs or lower water use in every situation, and living mulches can compete with crops for water and nutrients if not managed carefully. It’s the weed suppression and soil-health benefits, with sustained ground cover, that make it the typical standout advantage.
