I never put any on centipede unless the soil test comes back low. Even then, it is a once a year application as 1/4 lb P from solution grade 20-20-20.
I was thinking of using on various warm season grasses. I normally don't use any P. I was looking for a good source of iron & micros. I didn't think that would be enough P to hurt but if you think it is I will take your advice.
