Explain two benefits of mulching around garden beds in terms of water management and soil health.

• A. Increases evaporation; reduces soil organic matter
• B. Reduces soil evaporation and weeds; moderates soil temperature; as organic mulch decomposes, adds organic matter
• C. Attracts pests; blocks drainage
• D. Increases nutrient leaching; causes soil compaction

Answer: (B)

Mulching around garden beds helps manage water and support soil health by creating a protective layer on the soil surface. For water management, the mulch reduces soil evaporation, so the moisture stays in the root zone longer and you don’t have to water as often. It also suppresses weeds, which compete for water, and it moderates soil temperature, keeping roots cooler during hot spells and warmer when temperatures drop, which helps moisture stay available to plants. For soil health, organic mulch adds matter to the soil as it slowly decomposes. That added organic matter improves soil structure, increases porosity and water infiltration, and feeds soil organisms, all of which boost soil fertility and root growth. In short, the right mulch conserves water, reduces weed pressure, stabilizes temperature, and gradually enriches the soil as it breaks down.
