What landscaping technique can help reduce water evaporation from soil?

Applying a layer of mulch is an effective landscaping technique for reducing water evaporation from soil. Mulch acts as a protective cover over the soil, which helps to retain moisture by providing a barrier against direct sunlight and wind, both of which can contribute to soil drying. Additionally, mulch can prevent the soil from becoming compacted, further aiding water retention and improving overall soil health.

Using mulch also offers additional benefits, such as suppressing weed growth, which can compete for water and nutrients. Furthermore, as mulch decomposes, it contributes organic matter to the soil, enhancing its ability to hold moisture over time. This technique is particularly valuable during hot, dry periods when maintaining soil moisture is crucial for plant health.

While other options like increasing mowing height or planting drought-resistant species can have their own advantages in water conservation and plant health, they do not directly address the issue of evaporation from soil as effectively as applying mulch does. Regularly aerating the soil can promote better water infiltration and root growth, but it does not specifically limit evaporation.
