Great for maximum green growth with added potassium and micronutrients. The inclusion of iron helps promote a beautiful, dark green leaf color, ensuring your lawn stands out with that rich, healthy look. Whether you’re prepping for the season or maintaining peak color, the balanced formula provides both immediate and lasting results for lush, vibrant turf.

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 steady growth later. The immediate-release nitrogen delivers a quick boost, encouraging lush, vibrant leaf growth right away. Meanwhile, the slow-release portion steadily feeds your turfgrass over time, preventing those wild growth spurts and instead promoting a consistent, even lawn. This balanced approach keeps your grass looking great today, while setting it up for healthier, more manageable growth down the road.

If you want a fertilizer that gives your lawn an immediate pop of green and continues to feed it over time, Flagship 24-0-6 has you covered. The added potassium supports overall plant health, while the micronutrients and iron help maintain that vibrant, eye-catching color. Whether you’re prepping for a backyard barbecue or just want to be the envy of the neighborhood, this blend is designed to get you results—fast and for the long haul.

Flagship is loaded with an impressive 6% potassium, 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!
