Spongy Zoysia Sod at 8 Weeks: Check for Leaks

Emerald Zoysia installed 8 weeks ago on prepped sand/soil. Now lumpy and very spongy. Soil prep was perfect. What causes this?

Lift & Look

Gently peel back a few pieces. Check:

• Soil moisture: saturated? → irrigation leak.
• Root depth: shallow? → overwatering.
• Organic layer: thatch buildup? Unlikely at 8 weeks.

Hidden Leak Suspect

"Spongy" often means waterlogged soil. Check water meter with all off. Inspect valve boxes, heads, lines. A slow leak creates a sponge zone.

If No Leak

• Reduce irrigation frequency; increase depth.
• Verticut lightly if thatch >½" (rare this early).
• Roll to firm surface (water first).

Spongy sod isn't normal. Find the water source.
