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.

Works great. My dogwood, magnolias and hydrangeas look so much better and healthy. Easy to follow mixing directions. I am pleased with the fast results

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.

If you want that lush green lawn then add some iron to it. Iron makes everything strong and that includes your lawn. I have not seen this product for a very long time so when I came across it I was so surprised and of course I had to have it. If you have never used Bonide Liquid Iron on your lawn you should try this one. The price is really great and the results even better. I use an old Miracle gro liquid sprayer to apply to my lawn, just put the Bonide in the sprayer and go, within hours your lawn will be as green as the Emerald City! I am serious, you will have the best looking lawn in your neighborhood! One helpful hint when using this product, do not use it when it is hot. I use when them it is below 80 degrees. So if your lawn is lacking the luster of that deep green we all desire, or your plants are yellowing then try Bonide for a beautiful, nutrient rich soil that will have you being the envy of the neighborhood. Green will surely be your new favorite color!
