Unfortunately, the Pro-Mate 22-2-4 Fertilizer with Trimec Post-Emergent is not labeled for St. Augustine grass. However, we do have the Ferti-Lome Weed-Out Plus Lawn Fertilizer 25-0-4 which is safe for St. Augustine (do not apply to Floratam or improved varieties of St. Augustine) and has very similar nutrient amounts as the Pro-Mate 22-2-4 Fertilizer with Trimec Post-Emergent.
