    I'm having some serious issues with my yard and having a hard time figuring out what to do. Here's a timeline of my yard

    August of last year - new house, new yard, soil in the front is mainly clay, soil in the back is nice, no trees in front yard, back yard has several tall pines- tilled yard incorporating starter fertilizer, laid 950 sq yards of centipede sod.

    The sod took off great, real thick and green and growing nicely, no weeds

    October - spread Scott's winterizer

    March - since no real signs of weeds, spread Scott's southern lawns formula at end of March

    April - tons of weeds in the back yard, but I can deal with them. The front yard is where the main problem is. I think I have brown patch which is coming and going. I first noticed it about the second week of April. I bought some fungus spray but did not apply it. I took the advice of someone who told me I probably wasn't watering enough and also said I put down the wrong fertilizer. I upped my watering schedule and it seemed to help. On his advice I also spread some iron. We got 3+ inches of rain this past Saturday so I hadn't watered until tonight. In the meantime, the grass has made another turn for the worse. Basically, in the affected areas, the leaves fold in half. There are also some leaves with dark tips and some completely maroon in color. None of the spots seem to be completely "dead", but the areas are real thin and look very bad.

    May - Applied the fungus control at the beginning of this week but I guess it is still too early to tell if it is working.

    Can I please get some help diagnosing what my problem is and tell me what I'm doing wrong and what I can do to get back the lawn I had late last summer?

    Ok FIRST quit watering at night and start watering in the early morning

    Next have you ruled out GRUBS

    and lastly brown patch will spread if you dont keep your mower clean so after each mow WASH the underside of your mower and if you have a nother company mowing it for you have them start cleaning there equipment

    And yes it is too early for the fungicide to start showing any improvement but keep on using it

    I really should have invested in a sprinkler system b/c rarely do I have time to water in the morning. I try as much as I can to do it but more often I have to water in the afternoon or evening when I get home from work.

    As far as grubs, I haven't even thought about that. What signs should I look for?

    Good idea on washing the mower. Never though about that.

    As an update, I decided to mow a little lower this time. I've been mowing at 2in and went down to 1.5in. I don't know why but the grass looks much healthier generally looks better.

    Grass Masters - where in NC are you located?

    Im about 45 mins wes of Charlotte

    Now as far as grobs go take a shovel and cut out (DONT DIG) cut out a one sq foot section of grass and if you can could ten or more grubs then you have a problem

    If you do have a fungus problem you can use all of the Fungicide you can afford but until you stop watering at night you wont fix anything

    How much (in pounds) fertilizer did you put down on this 950 sq yds of centipede?The Scotts Southern shows 26 for the nitrogen rate,so if you bought a 50 pound bag x .26 = 13 lbs of actual N per bag.13/9(actually 8550 sq ft to the 950 sq yds) = 1.4444 of actual N.Centipede only needs 1 pound of N per year.I'm guessing you've put down too much nitrogen,since you said you applied in August,October,and March as well.

    I agree that this is some of the problem. You can fertilize 1 time a year on centipede. Here is some more reading.

    Just a quick little update -

    The yard seems to be doing alot better. I cut it a little shorter than I normally do. After doing so the grass looks much healthier. I do still have this one spot which needs some help. I've attached a pic so if anybody has any ideas please let me know.

    It is looking good JUST give the Centipeed time to grow in the bare spot and dont fret over it.....Trust me it will fill in in due time

    Or you could add some Plugs and help it along
