10x Overdose of Weed & Feed: Dilution Is the Only Fix

Sta-Green Weed n Feed (7,500 sq ft coverage) applied entire bottle to 700 sq ft. Lawn yellowing. Floratam St. Augustine? Label prohibits this product on Floratam.

Damage Assessment

10x rate = severe fertilizer burn + herbicide overdose.
If Floratam: herbicide (atrazine?) may kill it outright.

Only Remedy: Water

Water heavily, frequently—just below runoff—for 2–3 weeks.
No chemicals until full recovery (green, growing, mowed 3x).
Mow often to remove damaged blades.

Lesson

Calibrate spreader. Read label for grass-type restrictions. Measure lawn area.

Dilution and time are the only antidotes.
