all bags i have seen, iron would be listed sounds like the sales man dont know his stuff. seems funny you dont get no top growth unless its like a 100% coated fert, does it green up. as far as filling in most cool season grasses dont fill in very well they are just clump type grasses thats why you have to over seed.50% is coated allegedly per siteone, no marking on the label.
That's another question. This fertilizer has iron in it per the salesmen. The label does not list any micros like iron. Is this typical?
