I had my new lawn planted last fall. I live in South Dakota, so the lawn
didn't get quite long enough for the first last mowing before it got cold.

I am wondering what I should do to the lawn this spring. Should I put some
type of starter fertilizer on it now and then a crab grass preventer on it
by the end of May or can I put the crab grass preventer on it now?

Also, I had a couple of patches of brome grass that the roundup didn't quite
kill last fall. Is there anything that I can spray on this that will kill
the brome but not kill the blue grass?

Thanks

Doug
