Flagship is loaded with an impressive 6% potassium, which is higher than most other fertilizers on the market. At Yard Mastery, we see the results of thousands of soil tests and have noticed that a good percentage of these indicate low potassium, so you will find that we formulate potassium into most of our custom blends. Potassium helps lawns in times of stress by aiding in water uptake and retention.

As with all Yard Mastery blends, we have also included a nice amount of iron at 3%, which we all know is the secret to the deeper, darker blue-green color of any grass type, and a smattering of other micronutrients including boron, copper, manganese, molybdenum, and zinc.

All-Natural Bio-Nite™ in Every Bag!
Bio-Nite is a bio-solid filler we add to every bag of Flagship 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!
