Would Not RecommendI was disappointed with this product's performance. I applied the granules as directed, but unfortunately, I did not see any noticeable improvement in my lawn's color or health. Additionally, the spreader settings provided were inaccurate, and the product did not distribute evenly. Based on my experience, I've had far better results with Milorganite, which I've found to be more reliable and effective.

Fantastic Product
Would RecommendI've been using this product for a long time and results are phenomenal. You need to use as directed. Why the negative reviews! This product works as stated everytime. Brings the green out beautifully after about 7 to ten days. If your not getting good results I'd say maybe your lawn is lacking some crucial elements preventing the Iron and minerals from being taken up in the roots of the grass. Have your soil tested. Our soil around here is pretty horrible and rocky but the Ironite brings out th...

No Effect
Would Not RecommendGrabbed a bag of this instead of a product I've used previously and didn't realize it was iron oxide and not a useful product like iron chelate. The portion of my lawn with the competitor's product got some dark green, while the Ironite portion is still yellow. Threw the bag out like a dummy, so I wouldn't see a refund from their guarantee.

Your Lawns secret weapon
Would RecommendEasy to apply and really boosts your lawn. You will be suy
Make your neighbors jealous. Mine are.
Would RecommendIf you want a blue/green lawn, put this down in the early spring. The iron greens the lawn and the little bit of nitrogen feeds it.

Would RecommendI applied the Pennington ironite and I have noticed a difference in the color and health of my lawn within 2 weeks. I will continue to use this product in the future.

Greener lawn
Would RecommendI still think it’s too early to tell but my lawn definitely looks greener than my neighbors’ lawns
Would definitely buy again and recommend this product.
Would RecommendAbout a month after overseeding. My grass wasn't giving me that dark green look that. All my neighbors had. After doing some research and using this product. I can see it slowly getting that darker color that I was looking for. Although, I wasn't sure if it'll work. I only did half the recommended amount for my lawn. But the results are looking great. Thanks for a great product. Would love to have a Pennington tshirt.
