Hi, Kari -- there already is a 3" mulch of Buckwheat Hulls which never deteriorates. They are the by-product of making buckwheat flour for pancakes, etc. They much resemble lightweight raw lentils in appearance, so the ground remains a pretty brown color, and the weeds NEVER grow. AMOF, they are used to stuff bed pillows in Japan, to give one's neck a proper support, so it is said. One year I actually did dump an extra pail of hulls around the base of the 3 clematis growing up my porch trellis. I never felt that this gave the roots sufficient protection from the mid-summer 85-90-95 degree steady sun and heat. Your opinion...?
