    Ive got a problem lawn I could use some suggestions for. This lawn is new to my company this year. It is in a 10-15 year old development in Central Massachusetts. It is fescue turf that has some yellowing spots. Ive treated for grubs with dylox and those arent the issue, its spots here and there. The lawn used to be treated by Truegreen a few years ago and then has been left alone by the customer for the past 5, just mowing only. I cant get any answers one way or the other about how the grass was planted but it feels like it was sodded. I can feel it move under the wheels on the zero turn mower and if i can get my hand into the soil I can pull the grass up almost like new sod. I have tested for PH and fertilzer and fertilzer came back really low. I'm guessing the major issue is shallow roots and Ive shown them to the customer and said its probably going to take some time with some slow release fertilizer to fix the problem and its not going to be over night. I'm cutting it at 4.5 inches when we mow. It wouldnt be an issue but the rest of the neighborhood is green green green from all the rain we've had up here this past month and as soon as we got some dry weather her grass yellowed right up. Any suggestions as to what I can tell her or some other steps, short of irrigation, I can take to help her out?

    After 5 years the sod should be well rooted. Post some photos of the spots. Are they small or large?

    Lots of little spots the size of baseball's and some larger widespread areas. I've spot checked all over the place for grubs and have found nothing. About to go into Operating room, wife is having a baby, will snap some pictures later on

    Fungus? Insects?

    Get pics of the whole lawn and then get some real close up pics of individual blades.

    Good luck on the birthing thing. Dad.
    You said it is fescue...fine fescue or tall fescue? Did you treat for grubs without finding grubs?
    Many spots about 4 inches in diameter is likely dollarspot--but you know about that--right?
    Show us some pictures.

    You are saying it is not irrigated and the complaint is brown spots. Wouldn't you expect the problem to be lack of water. Does it look OK in the shade and look brown in the sunniest spots?
    Slow-release fert is not really a cure for shallow roots

    You said lots of rain. That can literally wash the green out of the grass.
