During which season is sheet mulching recommended?

• A. Spring
• B. Summer
• C. Cold Season
• D. Fall

Answer: (C)

Sheet mulching is most effectively recommended during the cold season, particularly in late fall or early winter. This timing allows the layers of organic matter, such as cardboard or newspaper combined with compost and mulch, to decompose slowly over the winter months. This process enhances soil health and builds nutrient-rich soil by spring, encouraging robust plant growth as temperatures rise.

Implementing sheet mulching during colder seasons also helps suppress weed growth before the next planting season begins. Additionally, the cold weather lowers evaporation rates, making it a suitable time to improve soil moisture retention, which is critical for the establishment of new plants.

In contrast, applying sheet mulching in other seasons may not provide the same benefits due to warmer temperatures leading to quicker decomposition and possible moisture loss, which is less than ideal for soil conditioning.
