Stump grindings

Stump grindings are what the grinder leaves in the hole. Illinois Extension says the grindings from a stump typically get mixed in with the surrounding soil as the blade chews up the stump. The result is a blend of wood chips and dirt.

This mix is not like good garden soil. Iowa State Extension says the shavings change the structure, moisture-holding capacity and nutrient balance of the soil. Wood that breaks down also uses up nitrogen, a problem called nitrogen tie-up.

For a new lawn, Illinois Extension recommends hauling off the chipped debris and filling the hole with quality topsoil. Ask your estimate about removal, since many crews leave the grindings. See after stump grinding.
