Pennington Ironite Mineral Supplement

No. Unlike high-nitrogen fertilizers that force rapid growth, Ironite is designed to deepen the color of your lawn without triggering a growth surge. This means you can achieve a lush, green look without the extra mowing.

It is safe and effective for a variety of plants, including flowers, shrubs, vegetables, and trees. Because it is non-burning, you can apply it around your landscape without worrying about damaging delicate foliage.

You can apply Ironite any time of year. Because it focuses on mineral supplementation rather than aggressive nitrogen feeding, it is suitable for use across all seasons, even during the heat of summer.

The formula is non-staining, which makes it much easier to apply around walkways and patios compared to traditional iron-based supplements. However, it is always best practice to sweep any granules off hard surfaces back onto the lawn after application.

The added microbes work to improve soil health by helping your grass more efficiently access and utilize the nutrients already present in the ground. It essentially helps your lawn feed itself better, rather than relying solely on external fertilizer.
