Great Product!
This is not a fertilizer. If you use it as such, you will be disappointed. Iron-tone works great to help green up the foliage on your plants. Leaves turn yellow if they are stressed by high pH. Sprinkle some of this product around your plants to lower the pH and make iron available. Works great on petunia and calibrachoa (Million Bells) plants!
