Review: 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: Works great. My dogwood, magnolias and hydrangeas look so much better and healthy. Easy to follow mixing directions.

Easy to follow mixing directions. I am pleased with the fast results ### ⭐⭐⭐⭐ Review *by D***5 on 21 April 2015* It is still too early in the season to give a decent review. I bought this to help fix the iron deficiency symptoms my maple tree has exhibited the last few years. I applied it as a soil drench according to the directions on the label. I'm a little skeptical that the tree will get enough iron from the small amount applied as a soil drench (via the label instructions), but hopefully that did the trick. If it doesn't, I'll apply it to the leaves once they leaf out. ## 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.
