We live in Englewood, Colorado, and had a 3 car garage built in our backyard...we still have a fairly large yard, but since the garage was built, our yard has become more dirt than grass....It is winter time here and I don't know what to do with it...I want to have my beautiful grass back...but don't know where to start. Please help.
One possibility is that during the construction of your garage, there might have been a lot of construction "traffic" driving on, or parked on your lawn. That would cause quite a bit of compaction of the topsoil. And once the topsoil is compacted like that, it's quite difficult to get grass to grow again. If it's your entire backyard, and there was nothing parked there, or driven there, or stored in piles there, then it's probably another reason. But this one's common to many construction sites. Loosening the soil and then reseeding may solve that. Simple plug aeration before reseeding may also help.
