Today many of the lawns in the newer subdivisions have a hard time surviving due to the fact that when the lawn was established there was little topsoil present and very little organic mater in the soil profile. The oganic matter in composts promotes microbial activity and provides better water holding capabilities for the soil which in turn keeps the grass growing longer even if it gets a little dry. Topdressing with compost is beneficial for the soil biology and helps the grass stay greener longer. In some areas homeowners can find a rental yard that has a topdresser in stock to rent. Check it out and improve your lawn by topdressing.
