Why is mulching important in landscaping?

• A. It adds aesthetic value to the garden
• B. It helps retain soil moisture and suppress weeds
• C. It increases soil acidity
• D. It encourages pest infestations

Answer: (B)

Mulching is an essential practice in landscaping primarily because it helps retain soil moisture and suppresses weeds. When organic or inorganic materials are spread over the soil surface, they create a barrier that reduces evaporation of moisture from the soil. This is particularly beneficial during dry periods, as it keeps the environment more stable for plant roots. Additionally, a thick layer of mulch obstructs sunlight from reaching weed seeds, thereby preventing their germination and growth. This dual function of moisture retention and weed suppression is crucial for promoting healthy plant growth and maintaining the overall health of a garden ecosystem. While adding aesthetic value to the garden is a secondary benefit of mulching, it is not its primary purpose. Moreover, mulching does not inherently increase soil acidity, nor does it encourage pest infestations, making those options less relevant in discussing the importance of mulching in landscaping.
