Starter and Centipede Formulation (5-10-30 + Iron)
The go-to formula for Centipede lawns because it's low in nitrogen. Fertilize Centipedegrass based on the feedback from a soil test - your Centipede lawn may not need fertilizing at all and can be damaged, especially with too much nitrogen.
This is a traditional fertilizer mix used for generations in farming and landscape maintenance as a starter fertilizer. This formulation, at the recommended rate, adds a small amount of nitrogen, but is higher in phosphorus and potassium.
Phosphorus and potassium are important in early spring to encourage health and more prolific root growth in warm-season grasses.
Comes in 25 or 50 lb. easy-to-handle bags.
First Application in Spring: Applying 5-10-30 in spring to warm-season grasses such as Zoysia, Bermuda, and Centipede will encourage root recovery from the winter without creating lush growth. Warm-season grasses that are lush and green too early are subject to frost damage causing delayed green-up or in worst cased dead grass. For fertilization of established lawns, consult our Lawn Maintenance Guides.
This formulation that's high in potassium is also useful for treating bipolaris disease in lawns. Bipolaris is augmented by high nitrogen levels, coupled with low potassium levels, so this fertilizer is a common way to treat the problem.
New Sod: When laying sod apply 6 lbs. per 1000 square feet for Centipede (use the 16-4-8 formulation above for Zoysia, Bermuda, Fescue). For more information, read How to Lay Sod.
