Which statement describes an advantage of mulching?

• A. No chemicals, reduce water evaporation, source of nutrients and humus
• B. Bulky and requires a lot of material
• C. Can increase vine vigor
• D. It provides instant weather-proofing

Answer: (A)

Mulching offers practical benefits for the soil and the vine by protecting the soil surface, conserving moisture, and enriching the soil as it breaks down. An organic mulch forms a barrier that slows water loss through evaporation, helping the soil stay moist during warm periods. As it decomposes, it adds organic matter and nutrients, improving soil structure and increasing the humus content, which boosts water-holding capacity and microbial activity. Because it’s organic, it also avoids introducing synthetic inputs into the vine’s environment.

The other statements describe downsides or less universal effects. Mulching can be bulky to apply, which is a disadvantage rather than an advantage. Its effect on vine vigor is not a straightforward, universal benefit and depends on many factors. And mulch does not provide instant weather-proofing; it takes time to develop protective benefits.
