Product Description:

First off, let's just point out that Double Dark contains 6% iron. There are very few granular fertilizers available that have this much iron in them. We all know that iron is the key to that dark blue-green color, but...Double Dark also contains 16% nitrogen because one thing that so many people forget is that iron won't work if the lawn isn't actively growing.

Think about it: the lawn has to be growing in order to take in nutrients and what element stimulates growth? Answer: Nitrogen The secret to Double Dark is that nitrogen and iron are working together. Search around and you will hear people who say, "I was using Ironite but after a while, it just stopped working." That is because there is no nitrogen in that product to keep things growing.

The nitrogen we put in Double Dark Blend isn't over the top - it's just respectable at 16% and, one-quarter of that N is slow release. You will get some green from the N too, but it's not going to smack your lawn in the face and make it flush out a bunch of top growth. The nitrogen is really just there to stimulate intake. 

All-Natural Bio-Nite™ in Every Bag!

Bio-Nite is a bio-solid filler we add to every bag of Double Dark Fertilizer. Bio-Nite is the same thing as Milorganite, but instead of being sourced in Milwaukee, it comes from South Florida. We can tell you that it “smells like a whole lot of success!” The good news for you is that the smell tells you that the included Bio-Nite is feeding microbes in the soil every time you apply and they love it!
