Which method is suggested for conserving moisture for desirable plants?

Applying mulch and controlling competing vegetation with herbicides is an effective method for conserving moisture for desirable plants. Mulch acts as a barrier that helps retain soil moisture by reducing evaporation, insulating the soil temperature, and minimizing competing weed growth that can consume water and nutrients. By controlling competing vegetation through the use of herbicides, desirable plants can access more resources without competition, resulting in better moisture conservation and plant health.

Although frequent irrigation might seem beneficial, it can lead to shallow root systems and increased water loss due to evaporation. Planting in shaded areas can help reduce water usage, but it may not always be feasible depending on the terrain and desired plant species. Using only chemical fertilizers does not directly contribute to moisture conservation; in fact, it may lead to nutrient leaching and other environmental concerns if not used judiciously. Thus, the combination of mulch and herbicide control is a more holistic approach to ensuring that moisture levels are maintained for the health of desirable plants.
