When the pesticide ban was introduced, landscapers and home owners needed new tools to help establish sod and improve existing turf.  Gro-Bark® developed Gro-Turf®  - a top dress that was designed to help decompose thatch at the turf-soil interface and thereby promote better water penetration to the roots. Later, Gro-Turf® was adjusted to hold more water so that it can be used as a medium for overseeding as well as for an organic matter treatment. Today, Gro-Turf® is a dual purpose product fine enough to go through spreaders.
