Q.You Say For Centipede “fertilize The Area With A High Nitrogen Fertilizer.” Where Do You Get This.
It conflicts with papers from two state university centers and the biggest supplier of Centipede sod in my area. You should never add nitrogen to Centipede unless indicated by a soil test.

If desired.
Some people get impatient and want results, quickly. I would not recommend this, since it is unnecessary, but some people do have poor soils which will need to be fertilized, pending a soil test. This should ALWAYS be done prior to feeding, anyway.
