Sulfate formula designed to be immediately available to plants in need. Liquid Iron can be applied as either a foliar spray or soil drench. Carefully read directions before use. Review: Works on indoor plants as well - Following the instructions, I was able to rescue a very yellow coffee plant. It went from clearly being deficient to big, shiny new green growth. Doesn't mess with the soil at all or cause smells or mold from what I've seen. Can definitely stain, so I'd suggest drip trays. After saving my coffee plant I went on to use the rest of the bottle to great effect. Perfect for trees, folious plants and other iron-loving plants. Review: This is the real deal. I saw results in 4 hours! - I planted several baby maple trees this spring. We've had drought conditions in my area of NY, and even though ive been watering my trees they still started turning yellow. I ordered this Bonide Liquid Iron and did a soil drench, and at the same time I sprayed all the leaves of the trees. Within 4 hours, the leaves started turning green, and now 6 days later they're dark green. I read online that iron deficiency kills plants and trees if they're not treated, so I'm relieved I found this product and that it works. ## Features - CONTAINS IRON - Iron is a vital nutrient required by plants to form chlorophyll.

The directions say to apply it in the Spring for best results. I'll know how well it works then. ## Frequently Bought Together - Bonide Garden Rich Liquid Iron + Micronutrients, 32 oz Concentrate for Outdoors, Keeps Lawn and Garden Green - Ironite Plus Shrubs, Trees Plant Food Bag Granular 12-10-10 3lb - Espoma Organic Iron-Tone 3-0-3 Organic Fertilizer and Plant Food to Help Correct Iron Deficiency (Chlorosis). 5 lb.
