Sometimes after an application in the summer months, the yard will get a little tip-burn. The salts in the fertilizer may slightly burn the grass. Also in extreme temperatures, the weed control, which kills weeds, can stress your turfgrass creating temporary yellow appearance. This condition usually will go away after you mow your lawn and fertilizer has taken effect. Please follow the listed watering instructions to aid in the recovery of a lush green lawn. In the fall and winter, your Bermuda or Zoysia areas may turn yellow to yellow-brown after this application. This is normal for this time of year. The yard is going dormant and may not turn green again after this application.
