Yellow grass ---Neep Advises
Houston, Texas area, grass turns yellow in this very dry and hot
summer. I watered it 30 minutes every day and applied fertilizer in the beginning of summer. It doesn't work. Some parts of lawn are still getting yellow. Most of yellow parts are close to the concrete pave but no one was walking on the lawn. Any remedies? Any suggestion is welcome! Thanks in advance! HH |

Here in the Midwest, I cannot ever remember heavy watering or rainfall causing the
grass to turn yellow. This is probably a result of the grass going dormant for overall lack of water. It would be better for HH to water less often, but in larger amounts. Time of day is also a factor. He should water when the sun is low (early morning or late afternoon). I have found soaker hoses more effective than sprinkling in my area, which is in the midst of a drought. I can't do the entire lawn this way, but I concentrate on the yellow areas. I am barely keeping up with the hot sun and lack of rainfall, hoping for a change in the weather. Sherwin D.

By midwest you are saying you are up north? It's a whole other
ballgame down here in Texas and Houston is clearly part of the humid south, nowhere near the dry line of the "mid west." Most likely we are talking about St. Augustine or bermuda which indeed does turn yellow from overwatering. If the turf wasn't watered so much, it could be chinch bugs, but it's too early in the season for that.

Thank you all for your suggestions. But confusing. Is it overwatered
or overall lack of water?? Does it need iron? I just bought Ironite and plan to apply Ironite tomorrow. I posted some photos hehttp://www.imagestation.com/picture/...d/f355fb42.jpg http://www.imagestation.com/picture/...3/f355fb52.jpg http://www.imagestation.com/picture/...2/f355fb4b.jpg http://www.imagestation.com/picture/...7/f355fb47.jpg Any more advices?

I don't know what kind of grass in my lawn. I do have a sprinkler
system and every day I think I water it with about 0.3-0.5 inches of water. Someone suggest to apply Ironite. I will try that and water it every two days with more water.

You are watering too frequently with too little water, causing shallow
roots. Water every 5 days before 10:00 am or after 7:00 pm, with about 1 inch of water, which will reduce your overall water use. Put out a tuna fish or cat food can to see how long it takes to water 1 inch. Water Every 5 Days http://www.enewsbuilder.net/watercon....cfm?x=b11,0,w Ironite is made from mine tailings and is considered toxic waste. Return it and get your money back.

Rather than guess, take a spade and cut a chunk of sod from one of the yellowed spots and from one of the green spots (don't worry, you can replant it easily). Look for: 1) soil moisture well down into the root zone in both places, or just one? 2) do the root systems seem equally well developed in both places, or just one? 3) do you see insects, grubs, etc. in one sample? 4) do the roots look and smell the same? 5) are you dealing with similar soil types? 6) are there different amounts of thatch (dead material just above the soil) 7) do the grass blades look similar or different when you compare the two sods? (same width, same basic structure?) I'm guessing that you're watering too little, too often. About an hour after you water, the soil should be damp about 4-6" down from the surface, with no puddling or ponding on the surface. Deep, relatively infrequent waterings encourage deep root growth -- 3/4 to 1" of water is generally recommended at a time in Houston, then watch for signs of wilting before watering again. My other guess is that the yellowing you're seeing is due to something wrong with the root system -- a fungal disease, grubs or other insects, or something odd in the soil (thin soil over rocks, perhaps?) Watering help: http://aggie-horticulture.tamu.edu/c...ter/lawns.html I believe you said you were in Houston. You might also want to submit samples to your county extension service. Kay |
