What role does mulching play in sustainable landscaping?

• A. Increases soil acidity
• B. Retains soil moisture and suppresses weeds
• C. Provides a decorative element only
• D. Reduces soil temperatures

Answer: (B)

Mulching plays a significant role in sustainable landscaping by retaining soil moisture and suppressing weeds. When a layer of mulch is applied to the soil surface, it creates a barrier that reduces evaporation, keeping the soil moist for longer periods. This is particularly beneficial during hot weather or in regions with limited water availability, as it helps to maintain healthy plant growth with less frequent watering. Additionally, mulch acts as a natural weed suppressant. By covering the soil, it blocks sunlight, making it challenging for weed seeds to germinate and grow. This not only reduces the need for chemical herbicides but also lessens the labor involved in manual weeding, contributing to a more sustainable gardening practice. While increasing soil acidity, providing decorative elements, and reducing soil temperatures can be related to mulching, they do not encompass the primary benefits that truly make mulching a vital practice in sustainable landscaping, which focuses on water conservation and weed management.
