A nice, thick lawn requires healthy soil as its base, but it's difficult to make changes to the soil once grass has been established. Top dressing can improve the soil without killing the existing turf.
Top dressing a lawn is the process of adding a thin layer of material over the lawn. Top dressing benefits the lawn as it builds up the quality of the soil over a period of time.
Top dressing can correct the following problems:
- Depletion of nutrients due to leaching, neglect, or repeated use of chemical fertilizers.
- Bare spots from variations in soil texture and nutrients, heat, drought, or other environmental damage.
- Uneven terrain caused by winter freezing and thawing, water runoff, tunneling critters, or general soil settling over time.
- Compacted soil in high-traffic areas or low-lying places where water pools.
- Low spots due to rotting tree roots, settling after underground pipe or cable installation, or erosion.
