In Atlanta apply fertilizer fortified with Iron to maximize color of Bermuda and Zoysia lawns. We are fertilizing respective lawns with a slow release granular fertilizer containing Nitrogen, Phosphorus, and Potassium, but it’s the iron in Atlanta Lawns that really intensifies the color.
There are several fertilizer blends appropriate for Bermuda or Zoysia lawns in Atlanta, but check the label prior to buying because not all contain Iron.
We like using something close to a 40% slow release blend of “30-3-9” with 2% Iron on Atlanta Lawns, and though you don’t have to use such a high grade product, something similar should be considered for best quality in Atlanta.
Be careful to blow fertilizer off of walks and drives, as the iron can stain hard surfaces.
