Moss tends to occur in lawns with which condition related to fertility?

• A. High fertility
• B. Low fertility
• C. Moderate fertility
• D. Very high fertility

Answer: (B)

Moss tends to appear when the lawn isn’t providing enough nutrients for the grass to grow thick and vigorous. In low-fertility conditions, turf growth slows and becomes patchy, leaving space for moss to establish. Moss also tolerates moisture and shade well, so the weak, thin grass can’t shade it out, especially on acidic soils. By using appropriate fertilization to boost turf growth and density, the grass crowds out moss and reduces its spread. In short, low soil fertility creates the ideal setting for moss, whereas healthier, well-fertilized turf resists it.
