Guaranteed Analysis: Water Soluble Iron (Fe) 1%
— Derived from Ferrous Gluconate, DTPA Iron, and EDTA Iron

Notes:
— Please store the fertilizer upright in a cool, dry location away from children. The pump head (if you have the older version) and dropper cap are not leak proof. For optimal shelf life, store out of light.
— Keep the tip of the pump clean of debris. Wiping the pump tip after each use helps prevent a mineral crust from developing. If the pump gets blocked up, it can cause the fertilizer to spray in a random direction, so run the pump head under warm water until the blockage melts away.
— Warning: Fertilizer can be irritating if it gets into your eyes, nose, or mouth, and it can cause stomach upset if swallowed. If you get Easy Iron on your skin, rinse it off. If you get it in your eyes or mouth, rinse thoroughly for 15 minutes. For USA customers,  reference the poison.org website. For Canadian customers, reference dpic.org.
