    I want to kill off about half of my rear lawn and install planting beds(its a mowing hassle right now)

    I;ve never done any larege area spraying this early in the season and although there is some greening going on now I think it might be a little too soon for the grass to process the chemical adequately.

    Your opinion? thanks

    What is your average day temp?

    You won't get the fast uptake right now. Although Round-up will work, it'll be slow to see the results and you may not get as good of control as you'd like. You could try an ester based nonselective herbicide.
  4. Round up is slow, and results aren't as good when air temps are low. Plants you are trying to kill need to be actively growing

    When weeds are actively growing add Nitrogen to the Roundup for faster uptake and response.

    If you will add a small amount of (lo-vol 6) or some banvel 2,4-d mix to your roundup it will help a great deal. But don't add too much because all you want the 2,4-d to do is help the uptake of the roundup especially in the broadleafs. I would only add the equivilant of 2 to 3 oz. per acre of the 2,4-d.
