May have over applied Urea to bluegrass lawn in Indiana on March 19. Had 6-8 inches of rain in April another two inches in last two days. Almost ten weeks later, I am just starting to see small brown patches and some yellowing of grass in other areas. How long after over applying Urea would I continue to see brown patches and yellowing? What can be done besides watering to correct. Will hot weather in summer further stress my lawn? Any info will be appreciated.
