Topdressing is the practice of covering the turf with an 1/8-inch to a 1/4-inch layer of weed-free topsoil or screened organic compost. Topdressing is especially helpful in resuscitating lawns previously sterilized by chemical use. The perfect time to topdress is just after aerating, filling those tiny holes with loose, rich organic material.

Proper topdressing requires that the entire area is spread evenly with compost, making sure that the material goes inside of the soil and not just  on top of the grass. When topdressing a small area, a rake or garden lute can be used for this job. Large areas may call for the use of either a drop or broadcast spreader, which both apply compost as they are pushed.
