About this episode

This episode discusses the relationship between putting green firmness and surface organic material.

The firmness of putting greens varies with the surface organic material. More organic material in the top 2 cm (0.8 inches), and greens are softer. I discuss terminology, the relationship between firmness and organic material, and what you can do about this.
