Grass clippings are classified as which type of mulch?

• A. Acid mulch
• B. Non-acid mulch
• C. Neutral mulch
• D. Fertilizer mulch

Answer: (B)

Mulches are often categorized by how they affect soil pH. Grass clippings don’t significantly lower or raise the soil’s acidity, so they’re considered non-acid mulch. Their pH is close to neutral, and as they break down, they add organic matter and some nutrients, but their impact on soil acidity is minimal. That’s why this item labels them as non-acid mulch. The other options don’t fit this acidity-centered view: acidic mulch would lower pH, while fertilizer mulch refers to nutrients released during decomposition rather than the mulch’s effect on pH.
