Here' s my deal. Summer of 2001 I plowed up, and dragged out my heavy sodded area for a plot. I had suggested lime spread this past late summer. I' m discing it up again here soon, or at least planning on it. My question is should I disc it, wait for spring growth to start, spray roundup, then plant my seed after? Or is there a weed killer I can disc in thats recommended before planting? I don' t want to go through all this, and it gets over run with weeds.
