    How well does Ironite(Iron) green up a lawn? A friend of mine was asking me about Ironite and I had no clue. He told me that someone suggested it to him and he had no clue either. Is Iron in most fertilizers, and how vital is Iron to the soil as opposed to N-P-K and lime? Do you most of your spread Iron on your lawns? Any info will be a big help. Thanks.

    You're right! Since Iron is in most fertilizers, NPK and lime are the most critical factors towards greening up the lawn (actually, water is, but that's a different story).

    Professional athletic fields and golf courses will use a liquid form of Ironite to maintain that unnaturally dark green that those guys are paid to maintain. However, Iron only greens up grass for so long, so it's really just a temp fix. Those guys have big budgets, so they're not afraid to spray it regularly.

    The bottom line is that Chlorophyll makes grass green, not Iron. Iron, along with several other elements in the soil contribute to the plant's manufacturing of Chlorophyll. As long as your fert program is well-balanced with the essential micronutrients you should be fine.

    That being said, if you want a quick green for a specific reason, say, for example, the customer wants a really green lawn in time for Memorial Day, then, yes, Ironite would be a quick fix. But otherwise, you're wasting your time.

    I've had mixed results with Ironite. It is good for Rye however it can stain concrete although I have not personally ever had this happen. It will be on fert bags as Fe which is the element from the periodic table as a micro-ingredient. Say you buy a bag of fertilizer with micros, it should be listed. Iron and all other elements need to distributed in a form that can be freely available to the grass otherwise it is simply wasted. Micros are needed less than macro ingredients which are you NPK the 3 numbers on the bag. They stand for Nitrogen,Phosporus, and Potasium. These elements are needed by the plants in greater amounts than micros. Depending on what variety of grass you have your cooperative extension website should tell you how much you will need. Hope that helps.
