I applied Ironite to my lawn in May and my grass became very green, even while my soil had tested alkaline. Next spring, I will definitely use Ironite again

It's a good additive

In western Colorado we have to use a lot of mulch to change soil texture. In consequence, sometimes the nitrogen and iron gets locked in the soil causing yellowed plants and leaves. This product unlocks the iron and restores the plant vigor
