St. Augustine Weed & Feed (20 lbs) typically covers 5,000 sq. ft. and is formulated to feed lawns while controlling tough broadleaf weeds like dollar weed, plus others like chickweed and clover. Common brands such as Sunniland and Rite Green (14-0-6 or 20-0-6 NPK) are designed for St. Augustine, Centipede, and Zoysia grass, using Atrazine for post-emergent control.
