How Does 24-0-6 Flagship Help Create a Thicker, Greener Lawn?
Flagship provides nitrogen to support healthy growth and includes 3% iron to promote a deep blue-green color. Its 6% potassium content helps turf manage stress by supporting water uptake and retention. The formula also contains micronutrients and Bio-Nite™ to support soil microbes and overall turf performance.

How Much 24-0-6 Flagship Should You Apply per 1,000 Square Feet?

Apply to dry turf, sweep excess from sidewalks and driveways to help prevent staining, and water it in within 48 hours with at least ¼ inch of rainfall or irrigation.

Can 24-0-6 Flagship Be Used on All Grass Types?
Yes. Flagship is suitable for established cool-season grasses such as Kentucky bluegrass, turf-type tall fescue, and perennial ryegrass, as well as warm-season grasses including bermuda, St. Augustine, zoysia, centipede, and bahia. Apply only when turf is actively growing and always follow the product label.
