I sowed a 1 acre area of our land in a pasture mix about a month ago. It is all coming up quite nicely now. The majority of it is about 6 in tall. I was wondering what, if anything, I should do with it before winter. Should I mow it, or just let it go? I have some weeds that have grown up in it as well. Is there anything I can spray it with to kill the weeds, but will not hurt the pasture? This is my first time doing this, so any info would be appreciated. Thanks.
