Hello,
I am building a new home, and it is near completion.
The construction crew leveled off the lot, and then placed existing
black dirt on top.
Over the past month, the entire yard is full of weeds.
Guess there was alot of weeds existing in the black top soil.

Once I move in (in about a month) I want to plant grass seed.
I am a newbie, and need to know what the best course of action is.

1. Should I somehow kill all the weeds first? If so, what is the best
and least expensive way.

2. Should I leave the weeds, plant the grass seeds and then let my
future mowing and composting of grass cure the weed problem?

I live in Chicago, and the weather is really cold in the winter and
really warm in the summer. I have heard that early fall is a good
time to plant a new lawn.

Also, any recommendations on a good grass seed to use for this
climate?

Thanks so much.

Rick
