It's been approximately 36 days since I seeded my lawn so I thought it was a good time to provide another update. Let's start right off with the pictures.
The front yard:
The back yard:

As you can see, I'm doing fairly well considering the circumstances we've had as far as weather. Before seeding, I was concerned that we wouldn't get enough rain to keep the seeds viable, and with the seeded area being roughly 2 acres, I didn't have the time or resources to water it all. Turned out that we had just the opposite: too much rain! So much, in fact, that most local rivers set historic flood levels. That said, I was happy that some of my seed actually made it through all that rain. I did have most of the seed in the side yards wash away so now I'm mainly focusing on the front yard and the back yard.
These pictures were taken about 2 days after I mowed it for the first time. With my mower on it's highest setting, I knew I wouldn't be cutting most of the grass, but I wanted to cut down some of the weeds so they didn't take control of the yard. In the close up shot of the grass, you can see one of the fuller areas of the yard. You can see quite a bit of good Kentucky Bluegrass, but there is also quite a few undesirable grasses that cropped up. If anyone can identify them, leave me a comment.
In some areas of the yard I have seedlings that are quite skinny and don't seem to have grown much above 1" or so. I wonder if I didn't give them enough fertilizer to start with, or if too much fertilizer washed away in the rain.
Lately, I've been watering once daily to make sure that the grass I do have doesn't die this summer. Luckily, this summer has been very mild. We've only seen a few days that got into the upper 80's. Mostly we've been in the high 70's to low 80's.
The questions I need to get answered at this point are:
1. When should I taper off the watering?
2. Should I give it some more fertilizer now to stimulate growth and filling-in?
3. Can I over-seed some smaller areas now if I baby them with watering, etc?
I'll post back when I figure out what to do!
