What is the purpose of topdressing in landscape maintenance?

Topdressing is primarily done to add a layer of material, which can include organic matter, compost, or soil amendments, to the surface of the soil. This practice serves several important purposes in landscape maintenance. By improving soil structure, topdressing enhances the soil's ability to retain moisture, supports healthy root growth, and increases nutrient availability for plants. The addition of organic materials can also help improve microbial activity in the soil, which is crucial for soil health and plant vigor.

In contrast to other choices, which may address specific issues like weed prevention or the creation of new planting beds, topdressing's main goal revolves around enhancing the physical and biological properties of the existing soil. This makes it a beneficial practice for overall plant health and landscape aesthetics, as it promotes a stronger and more resilient environment for plants to thrive.
