Weed free lots????

Well, the active ingredient in Roundup is "glyphosate", a chemical patented by Monsanto. It kills plants by supressing an enzyme. It's moderately toxic and breaks down pretty quickly in the soil. But the weeds will come back in a couple of months or less after being sprayed. That's why I don't think it's a great long-term solution, but it's a good way to get rid of stuff so you can get something else started. You can buy the regular Roundup grass and weed killer, which will probably work well enough, or you can buy the more concentrated kind called Roundup "Pro Dry", I think. Sometimes people mix Roundup with other herbicides like Diquat or Sythe (Sythe is actually made from organic fatty acids) for a faster kill off. (Roundup alone takes a little longer to kill the plants) Like Roundup, both of these break down in the soil pretty fast and aren't very toxic. If ya gotta use chemicals, these are some of the more benign.
