Nature’s Source Plant Food, formerly Daniels Plant Food, has been used by commercial growers throughout North America for nearly 20 years. The same 3-1-1 formulation that certified organic growers use in their greenhouse production is the same that’s now available to home gardeners. Like its commercially available counterpart, the new Nature’s Source Organic Plant Food 3-1-1 for retail contains oilseed extract, a natural and sustainable source of plant nutrition. The formula is listed with the Organic Materials Review Institute (OMRI) for use in certified organic production, and it is also a USDA Certified BioBased Product.
