New St. Augustine Sod Yellowing: Patience Over Fertilizer

Week-old St. Augustine sod is yellow but greening slightly. Heavy watering continues. Should you fertilize to boost color?

Rooting Comes First

Sod must root before it can uptake nutrients. Test by gently tugging pieces—resistance means roots are anchoring. Until then, fertilizer leaches away, wasting money and risking runoff.

Why It Yellowed

Sod stacked on pallets shades lower pieces, causing chlorophyll loss. Sunlight alone reverses this in days.

What to Do

• Continue daily morning watering (reduce frequency as roots establish).
• Do not fertilize until fully rooted (typically 2–3 weeks).
• Mow only when grass is 3.5–4 inches tall, removing no more than 1/3 blade height.

Patience and proper watering beat premature fertilizing every time.
