Product Description:
Yard Mastery Flagship Blend contains both immediate release and slow-release nitrogen. It’s a winning combination because you get some green now and even more later without kicking the lawn in the face too hard. This is our best-selling fertilizer for a good reason: it works. Thrower down and you will see results within 6 - 7 days and the green will last up to 45 days.

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 are indicating 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!
