grass/lawn question

[etherfast]

Hi,

The Grass on our backyard is growing these weird green fuzzy things the are very like flat to the ground .. I am not really good at explaining and hope u guys understand what I am talking about. These green this are slowly killing our lawn. We tried digging up the grass and thrown it away and left it bare dirt for a couple weeks and it came back. What to do?

Thanks

Please take a photo and post it as weird, fuzzy things could mean almost anything!! The only thing that comes to mind is crabgrass

Looks like it could be moss. If the ground is packed down and in shade or damp, you'll get moss. That's not necessarily a bad thing if grass won't grow there but it does tell you you need to work that area if you want grass to grow there.

How do i fix this "moss" thing because there are some other small spots in the middle of the my lawn.
