Why Winterizer Fertilizer Harms Bermudagrass

Applying winterizer to bermudagrass wastes money and risks cold damage. Bermuda starts storing root reserves in mid-September for spring green-up. High-nitrogen fertilizer (common in winterizers, e.g., 30-0-10) forces top growth, draining those reserves. Instead, stop fertilizing by early September. If needed, a low-nitrogen, high-phosphorus/potassium blend (like 5-10-15) is better, but hard to find. References at bit.ly/winterizer.
