What Customers Are Saying
The Ironite product is highly effective at greening up and fertilizing a variety of plants, including lawns, shrubs, trees, and flowers. Many customers reported seeing noticeable improvements in the color and vigor of their plants after using the product, with some noting a "complete turnaround" and plants "greening up very quickly." Ironite seems to work particularly well for plants suffering from iron deficiency or pH imbalances in the soil. The product was described as easy to apply, with good value for the price, though a few customers noted it may need to be reapplied more frequently for potted plants.

Would RecommendUsed this product for its acidifying nature along with the NPK. Did not purchase the regular ironite due to low NPK and added calcium . Our soil and water in Dallas already tends to be slightly alkaline. The product increased the health and vigor of my St Augustine grass. The sulfur and iron along with balanced NPK is a good tonic for struggling plants. Only negative is it should be available in larger sizes

Great for soil starved of Potassium and Phosphorus
Would RecommendSoil testing in my area in Virginia showed the soil was lacking in Potassium and Phosphorus, which explains why my lawn would always look great in spring and early summer. But stress out by August and die off. Potassium is needed by the grass for these stressful periods, and Phosphorus helps to build a healthier soil. I applied this when the lawn looked hopeless. And it miraculously came back to life in about a week.
