Here's our back yard April 9th, 2012. Just a couple days after Dan and his brother Matt planted seed. Nothing had grown yet, so this is the starting point:
Here's another picture from 2 1/2 weeks later, on April 26th. Looking a little bit better (the leaves on the trees sure help huh) when you can compare the pictures side by side, but we felt like NOTHING had happened. Like we were just crazy people watering our weeds and dirt 3 times a day!
And here it is today, June 14th which is almost 10 weeks of watering, 1 round of fertilizer and 2 rounds of weed and feed.

We bought a mower and an edger last Saturday and 9 weeks after planting the seed, Dan gave it it's first mow, pretty exciting for us! Parts of the lawn are still pretty sparse but other parts were very tall and thick! Those weeds were gnarly, but the weed and feed had shriveled them quite a bit, it's awesome stuff.

It's getting better, hopefully in another month or 2 it will be mostly filled in. Growing grass takes patience man! I really understand what the saying "Just sit around and watch the grass grow" means a lot better now.
Funny story: So notice this plant growing in the back yard in the first couple of pictures? I drew in an arrow for you to see.
Well, I noticed that months ago and I thought, "Wow, they (the previous owners) did plant something in the backyard! How nice." Then a few weeks ago it flowered! How lovely. See? But then I looked up and into the field across the road from us and saw that it was FULL of the same thing! HA ha ha! Shows how plant ignorant I am. I laughed OUT LOUD at myself.
Dan dug it out and we sent it to the dump on Monday (you can see it's gone in the pic from today, if you scroll back up there). I thought it was pretty funny. We have a lot to learn. I don't plan to plant anything else this year, if we can get the weeds out, rake up all of the old rotting leaves and grow a lawn I will be satisfied. Plus I am scared to plant anything, because we have too many rabbits! Do you have rabbits? How do you keep them from eating your garden?
