Dr. Q’s PAYDIRT PREMIUM PLANTING MIX AND MULCH is specially formulated to see all plants through the difficult transition from cushy container life to tough, nutrient deficient, poorly drained soils and build a strong foundation for vigorous, healthy growth. It's a 100% organic, superior blend of aged mushroom compost, peat moss, composted fir bark and forest humus. Paydirt has no sewer sludge, which could contain heavy metals and other contaminants. Available in 2 cu ft and 1/2 cu ft bags for small and large jobs. This also bears the OMRI logo marking them as officially recognized organic planting materials by the national Organic Materials Registry Institute.
