Which landscaping practice is known to conserve water and reduce weeds?

Mulching is recognized for its ability to conserve water and suppress weed growth in landscaping practices. When mulch is applied to the soil surface around plants, it creates a barrier that helps retain moisture by reducing evaporation. This is particularly beneficial in maintaining soil hydration, especially during dry spells or in arid climates.

Additionally, mulch serves as an effective weed suppressant. By blocking sunlight from reaching weed seeds and seedlings, it inhibits their germination and growth. This reduces the need for chemical herbicides and manual weeding, leading to a healthier and more sustainable garden environment. With the dual benefits of conserving water and controlling weeds, mulching is a widely recommended practice in landscaping.

Sod installation might improve the immediate visual appeal of an area but is typically less effective in terms of long-term water conservation and weed control compared to mulching. Planting annuals can contribute to aesthetics and biodiversity but often requires more water and maintenance. Soil amendments, while beneficial for enhancing soil quality and fertility, do not directly address water conservation or weed suppression in the same way that mulching does.
