                          Don't be an idiot stay away from this garbage
                          This product browned my every inch of my lawn it touched. I had the greenest lawn in the neighborhood but not anymore. Stay away from urea based nitrogen. Customer service basically blames the consumer. So don't bother calling. I used on half on my front yard and the other half I did not apply to. Wish I never bought this 😕

                            Absolutely
                            I 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.

                                Good product, uneven granules and dust.
                                [This review was collected as part of a promotion.] The product works good, however the sample I received has lot of uneven granules and a high amount of dust. This dust was enough to create a small cloud of dust around me while using a manual hand help spreader. That being said I was breathing it heavily and that was not very pleasant. 3 stars is generous as the product stands.

                                  Worked perfectly
                                  Worked great! I had no weeds and grass handled out drought this season well.

                                  Should be called Sulferite...
                                  I noticed they changed the formula this year (2022), compared to last year. The Iron content dropped in HALF from 20% to 9.9% and the Sulfur content went up from 5% to 33%! So the greening effect is being caused by Sulfur more than by Iron. Sulfur will green-up your yard, but it certainly doesn't seem to last as long as Iron.

                                    Works very well
                                    [This review was collected as part of a promotion.] We have Bermuda grass and when we received the product we had to wait as it was super hot and dry to lay it down. Once we did and not to long after our grass turned greener, no weeds and it was fantastic to see when you drive past our front yard.

                                      [This review was collected as part of a promotion.] I really don't know how to review this product. My husband said we couldn't put it down until there was a good hard down pour. He said he has used this product in the past and was a good product.

                                        [This review was collected as part of a promotion.] Ironite definitely gave my lawn a nice green up! I mowed it to about the 1" mark, put down the ironite and watered in! A few days later, I had a beautiful green lawn that looked great even at night! Would highly recommend!

                                          OMG RESULTS!!!
                                          [This review was collected as part of a promotion.] We have a huge problem with moles and mole crickets so lots of areas in our yard are brown. I am mindblown at how good and fast this stuff worked! The 2nd picture is literally 7 days after the first picture/ first treatment. The grass is WAY greener, the brown spots have mostly filled back in with green grass. The whole yard is just softer and healthier looking as a whole and I am so impressed. My neighbors even made a point to come ask what we did because it made that much of a difference that they wanted in on the action. We have been blessed with a week full of rain this week too so I'm sure the yard will continue to improve. I definitely reccomend this grass treatment! It was so easy to just fill the spreader and then water water water!
