What date was it laid? I don't think it should be brown. I planted tall fescue on sept 6. It was 27 degrees F last night. Still green. I noticed some areas of mine that have stunted growth and slight brown tips, but you only notice close up. Have pictures?

It was just laid about 2 weeks ago. 90% of the yard is green but the very last section they laid is starting to go brown. Its weird. The section that is going brown was laid only a day after the rest of the yard. I took some pics but it really doesnt show how the grass looks.

The brown sports are near the rock or pavement? Can you get a close up of the brown spot?

Its near the stones in our front/side yard. Its not the best pic

I can't tell if that is a big seam to the right of the patch? If so perhaps it wasn't pressed firm into underlying soil creating an air pocket? Otherwise, that looks dead. Is it spreading? Might be disease, fungal or lack of water in that one spot.

Can you pry it up and look for grubs?

I looked underneth and didnt see anything. That is a seam on the right. Its not really spreading anywhere other than the one area. Like I said it was the last section they laid down. I was worried it might be too much water. Ive been watering it every day for about 10minutes or so. Thanks for helping try and figure this out.

If you didn't apply any fertilizer yet , most recommend synthetic before winter. Something like 30-0-4 or similar/around that mark. Vigoro makes a 36 N but it's slow release, go for something a bit fast. Hopefully the experts chime in, if not try the search feature and FAQ section. But I'd get something down and watered in soon.

Also watering 10 minutes a day might be on the low side for new grass or sod. I was watering 3 times a day for 10-15 minutes during September (it was very hot). Try a bit more , maybe 15 min morning and then again for 10 at 2 pm. Watering late in evening encourages fungus and disease on TTTF or so I've read here.

Thanks for the info. Its been very helpful. I started watering it 20 minutes a section once a day when it was first laid down but I was afraid I was over watering it so I cut it back. Ill have to try and water it more. Ill check on the fertilizer too. I know now is the time to do it . The landscape company only said to water it for the 20 minutes/section and nothing else. I had a really nice green lawn a few years ago when we first bought our home then Hurricane Sandy hit and the salt water did a number on the grass and then all the construction that went on finished it off. So now Im trying to do my research to make sure I have a super nice lawn next spring. I wish there was more I could do to help with the burnt spots from the dog urine but from what Ive read all I can do is flush the area after she goes and if it turns brown hit the spot with some seed. I never mind doing some work in the yard.

Also check with sod company its possible they fertilized before delivery.
