Reviving St. Augustine Sod That Dried Out After Installation

You laid St. Augustine sod in Houston, didn't water enough, and now it's brown at the edges with some green remaining. Daytime temps in the 50s–60s. Good news: St. Augustine is tough, and cool weather buys you time. Here's how to save it.

Assess the Damage

Brown, rolled leaves from the edges inward = drought stress. If sod pieces are lifting at the corners, roots have shrunk and lost soil contact. That's fixable.

Immediate Actions

1. Roll the sod. Use a water-filled lawn roller (rent one) to press roots back into soil contact. Do this when soil is moist but not soggy.
2. Fill gaps with sand. If edges won't stay down, brush coarse sand into gaps to stabilize and retain moisture.
3. Water deeply, then consistently. Apply 1 inch of water immediately. Then water daily (1/4–1/2″) for 2 weeks, skipping only if rain exceeds 1/2″. Morning only—no evening watering (fungus risk).

What Not to Do

• Don't fertilize yet. Stressed roots can't uptake nutrients; fertilizer burns.
• Don't mow until fully rooted (tug test: resistance = rooted).
• Don't apply weed control—herbicides hurt recovering sod.

Houston-Specific Notes

St. Augustine stays semi-active in 50s–60s. It won't grow fast, but roots will knit if moisture is steady. Watch for brown patch fungus (circular yellow/tan patches) if nights stay damp—reduce watering frequency if seen.

Timeline

• Week 1–2: Daily light watering; roll once.
• Week 3–4: Every other day; check rooting.
• Week 5+: Normal schedule (1″/week); first mow at 3.5″.

Most "dead" St. Augustine in cool weather is just dormant crowns waiting for water. If crowns are white/firm (not mushy/black), it will recover. Stay consistent—you've got this.
