Use this blend of minerals and organic matter from the Vermont Compost Company to revitalize last year's potting soil! Compost Plus adds texture and slowly releases nutrients throughout the season. It makes a great topdressing for annuals, houseplants, and even vegetables, eliminating the need for repeated applications of fertilizer.
Add 4-8 tablespoons of Compost Plus per quart of planting medium; 1-2 cups per 4 quarts of medium. All the ingredients are acceptable for use in certified organic production (manure compost, crushed, washed screened granite, vermiculite, bone char, mined gypsum, langbenite rock, sphagnum peat moss, kelp, blood meal). 6-quart bag.
