St. Augustine Weed Takeover in Miami: Hand-Weed, Compost, or Targeted Herbicide

Two-year decline, weeds winning, no chemicals. Hand-weeding works (one acre, daily sections, string lines)—but it’s extreme. Perennial weeds in FL don’t winter-kill.

Better: mow 2–3 inches, fertilize, water right. Replant thin spots with Floratam, Raleigh, Seville. pH <7.5, good drainage. Compost (1 cy/1,000 sq ft/year) feeds and suppresses weeds. If needed, 2,4-D/MCPP/dicamba as interim until turf thickens.

Healthy St. Augustine crowds weeds. Fix the culture first.
