Establishing St. Augustine Plugs in a Fescue/Weed Lawn

Complete Renovation for Successful St. Augustine Conversion

St. Augustine (Zone 9+) requires a clean start. Planting plugs into existing fescue and weeds guarantees failure.

Essential Steps

1. Kill all existing vegetation with glyphosate (Roundup). Wait 7–10 days.
2. Improve soil: Rototill in compost, humus, and sand if clayey. Level and grade.
3. Install irrigation (you're doing this next week—perfect timing).
4. Plant plugs on prepared soil. Keep moist—water 2× daily in heat until rooted (tug test).
5. Mulch with straw or Straw-Net to prevent drying.

Why Eradication Matters

Old grass and weed seeds will outcompete slow-establishing plugs. A clean seedbed ensures your investment succeeds.
