    Has anyone had any luck with iron on centi. or St. Aug. I have tried
    12-0-0 & 15-0-0 both with Iron and no luck. I tried to increase the amount
    and had gray spots where the leaves burned in the St. Aug.
    No luck with Ironite either.

    Liguid iron put on from hose end sprayer will definitely work. Need to keep it off the sidewalks etc. Or you can go organic with GREEN Sand...but this takes a few months to work but seems longer lasting than liguid iron.

    I am not sure of you climate. SA and Centipede will go dormant in the winter. The rule of thumb in zone 10 is get green before October. We have a year round growing season, but shorter days and colder nights cause very slow growth. To much Iron will turn the lawn black.
