1.   It can even be buried in the ground to prevent wetting the soil surface and encouraging weeds.

2.   Allow the new shoot and the rhizome, or horizontal root, to rest on the soil surface.

3.   Avoid excessive thatch, the nondecomposed organic matter between the soil surface and the base of the blades.

4.   Choose a partly shaded spot outdoors and sink the flat so the top is level with the soil surface.

5.   For best results, Wiigh-Masak suggests burying the dust near the soil surface, where oxygen-loving microbes will degrade the remains within six months.
