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.
