I'm new to this board so thanks in advance for any help. I had newly laid sod put down last fall (in September). This spring it was coming in very nicely. The yard looked lush and green and it was growing great.
Then, when it reached about 5" I cut it for the first time. That's when it went from great to horrible and now half of it looks dead and it's not really growing anymore in many places.
I'm not really sure what the heck happened. I live in Washington DC and it's not been hot and we've had rain so I don't think it's underwatered. I overseeded this week and have been watering but it looks awful and I can't figure out how cutting in once made it look like this since it looked great up until then. What can I do, if anything? Is it dead? Bad sod? Pics attached.
I am going to de thatch and try to lay more seed but not sure if that's the right move. Thanks in advance.
