Can you tell me about bleach as a weed killer?

Bleach is extremely toxic and should not be used on plants or weeds. Use vinegar instead. It will kill all the toughest weeds except things like blackberry vines. Just dump it straight on the weeds, making sure you get it down into the roots. If you have a lot to do it might take 2 or 3 gallons. I just used 2 gallons today on my weeds. (06/20/2007)

I have never used bleach, but have used salt. I have used it in between sidewalk blocks and under fence. It will kill grass, but is not a poison as so many of the weed and grass killers are. (06/20/2007)

Please don't! Both bleach and salt are long-lasting pollutants that do reach the groundwater. Try a flame weeder, a long torch that cooks the weed by boiling the juices in it. Very fun, actually, and teenage boys have been known to ask to do this chore. You don't have to dry up and burn the weed, just turn it into seaweed with it. They are cheap to use and organic, perfect for driveways and walkways where weeds come up through gravel or concrete.
I got this idea by reading Ann Lovejoy on organic landscaping. The ultimate solution is barriers, like deep gravel or bark over a layer of black plastic or thick newspaper. If weeds are coming up through your gravel, then double the depth of the gravel. (06/21/2007)
