Top dressing a lawn is the process of adding a fine layer of soil mix to the lawn surface and is designed, over a period of multiple applications, to improve soil structure. The addition of a predominantly sand based mix to a heavy clay-type soil will permit better drainage and promote better root zone development.
Another benefit of top dressing the lawn is that it will help to even out any lumps and bumps that are present on an uneven lawn, filling in any small hollows that may develop. Top dressing also stimulates the grass to produce new shoots and so results in denser grass cover helping combat the onset of weed and moss infestation.
Top dressing is normally carried out during Autumn. On heavy and compacted soil aerating the lawn before top dressing is highly recommended.
