Soil Mender Mulch consists of our Composted Cotton Burrs screened with a coarse screen. Soil Mender Mulch is composted for a longer period of time than the BTE, giving you a denser, more composted product, thus, making it easier to spread and work into the soil. Soil Mender Mulch is an ideal general-purpose mulch for amending clay or sandy soils. This product contains no chemicals, weeds, insects, or harmful pathogens. Soils low in organic matter and humus or with poor tilth and structure cannot be rejuvenated with chemical fertilizers. Soil Mender Mulch can quickly start improvement of such soils, since it begins to function immediately, restoring vital organic matter and humus to soils, regardless of soil conditions.
