What is the primary benefit of mulching around plants?

The primary benefit of mulching around plants is that it reduces evaporation and conserves soil moisture. Mulch acts as a protective layer over the soil, helping to maintain moisture levels by limiting the amount of water that evaporates from the soil surface. This is particularly important for plants, as consistent moisture is crucial for their health and growth. Additionally, mulch can help moderate soil temperatures, keeping the soil cooler in hot weather and warmer during cooler periods, which further supports plant vitality.

While reducing soil erosion, preventing weeds, and enhancing soil fertility are all noteworthy advantages of using mulch, the primary focus here is on moisture conservation. Mulch effectively creates a barrier that retains soil moisture, leading to better water availability for plants, especially in dry environments or during periods of insufficient rainfall.
