I'm not sure what's going on with my lawn and was wondering if someone could help me out. I live in Austin, which is a pretty hot and dry climate for the most part. Our St. Augustine sod was put in around mid-September 2005 and looked bad through most of the Fall/Winter. We recently had a few weeks of high humidity and frequent thunderstorms that dumped tons of rain around here, and our lawn seemed to go from brown and crunchy to lush and green almost overnight. I treated with Weed & Feed about two months ago and then spread Ironite a couple of weeks ago. Both treatments made the grass even more green and beautiful than before. Then, the past week we had pretty hot (95-100 degrees some days) and very dry (hardly any humidity) weather. During this time I went back to watering the lawn like before with the sprinklers, etc. Well, today I noticed a lot of bright, yellow blades scattered throughout the lawn. Upon further inspection it seems like one side of the blade has yellowed while the other is still green. There are areas like this throughout the front and back yard, and the lawn overall has faded in color from the deep green it had before. I tried to take some photos to show what I'm talking about so hopefully someone can help me figure out what is going on. It's very disappointing to do all this work and have our yard FINALLY look nice, only to have it look bad again in two days.
All help is appreciated!!
