    This lawn looked great two months ago...I really don't know what happend.

    We moved in to this house one year ago. The first thing I did was start the Scotts 4 step program. I also did some basic spot repairs. I had the lawn looking stellar this spring. It was really thick and green. But now its gone to the pictures below and I need to know what I've done wrong.

    I'm more concerned with the back yard since it is much worse than the front, but I would appreciate any input that I could get on what I need to do to take care of this as I am new to the St Louis area and am not familiar with the types of problems that are experienced in this region.

    I really enjoy working in the yard and trying to maintain the best lawn on my block, so it is really killing me having a yard that looks like this. I'll have to admit that I do not have a sprinkler system installed yet, so my watering isn't as regular as I would like, but this issue doesn't look like its due to a lack of water. Thank you in advance for your feedback.

    Did you use any weed-n-feed and what kind of weather have you been having?

    I'm guessing it has/had a disease - maybe brown patch or something like it.

    Yeah, I used some Ortho Weed-B-Gone early in the year to get rid of some clover. The weather has been pretty hot and dry over the past month. I do water, but like I said, I don't have a sprinkler system so its not on a scheduled basis.

    Do you think I may have burnt it up? The brown spots have a weird, matted down look so went over them with a rake to get the grass back standing upright. Not much grass came up so I don't think I'm dealing with grubs, but could be some disease?

    What do I need to do as a next step? I had planned to dethatch/aeirate this fall and overseed but it appears I could have some more work to do.

    Could a disease come on so bad in such a short time.

    What has the average temp and humidity been? It is the end of july, so the lawn going a little dormant won't hurt anything. Try and get it some water when you can and wait for the temps to begin cooling down. Renovate and for the spots like that, take a look at you soil structure (compacted clay) as the culprit. Take a soil test before you renovate so you can amend the soil while it is open.
    Many people on here see grass changing colors and for some reason have a spastic reaction and then start shouting disease names. Just remember, you need three things in the disease cycle: host, pathogen and enviornment. Take awaay any one of those variables and disease will not occur. Home lawns are the least susceptible to disease unless it is being kept in the extremes.

    It has been in the high 80s low 90s here for awhile with a couple 80 degree "cool downs" in there. Haven't got much rain and the humidity is always fairly high around here (50-90%)

    DCGreenspro,

    I hear you. However, in this area(East Tennessee) The pictures look a lot like brown patch. I know so because I have this very same thing in my own yard and have kept it watered properly. I applied some bayleton and it has begun to come back.

    I hate to put more chemicals on it if it is infact burning up...will this hurt it any more if it in fact does not have any disease.

    You might try watering it thoroughly first. If there is no greenup after a few days you might consider getting some professional advice locally before doing anything else.

    In this area, if the disease progresses very far the grass will oftentimes die and need to be reseeded in the fall. First year seeding is the most vulnerable to disease.
