Covington Liquid Iron Blend is a concentrated chelated iron fertilizer for lawns, trees, shrubs and garden plants. It carries 6% iron with no EDTA, plus 12% nitrogen, 3.3% sulfur and 0.05% manganese, and uses a sugar-based chelating agent instead of the synthetic EDTA found in many liquid iron products. It suits gardeners correcting yellowing between green veins, brown leaf margins or stunted growth on turf and ornamentals. The manganese and sulfur are extras that plain iron sulfate products usually lack, though the high nitrogen means it feeds foliage as well as correcting iron.

Covington Liquid Iron is a sugar-based chelated iron concentrate for lawns, plants, shrubs and trees. It treats iron deficiency, which can cause stunted or malformed growth. Iron-deficient leaves are green-veined with mottled yellow tissue between the veins, and foliage may develop brown leaf margins.
The formula uses sugar-based chelating agents instead of EDTA. It contains 6% chelated iron, 12% nitrogen, 3.3% sulphur and 0.05% manganese. It improves plant color and quality, promotes stronger root development and lowers plant stress while treating iron deficiency.
It works for both foliar and root applications. For trees, shrubs and bushes, apply it around the outside of the grow line according to the instructions. It can be used with herbicides, pesticides and fertilizers. It is made in the U.S.A.
