What is the benefit of using mulching in relation to irrigation?

Using mulching significantly reduces evaporation and helps retain soil moisture, which is critical for effective irrigation practices. When mulch is applied to the soil surface, it creates a barrier that slows down the rate of water loss due to evaporation, especially in hot and dry climates. This means that the water applied during irrigation remains in the soil for a longer period, allowing plants to access moisture more effectively.

Additionally, by keeping the soil moisture levels stable, mulch can promote healthier plant growth and reduce the need for frequent irrigation. This can lead to more efficient water use, which is particularly important in areas where water resources are limited. Overall, the retention of soil moisture through mulching supports sustainable irrigation practices and promotes the overall health of the garden or landscape.
