Sorry, but the bleach weed killer 50/50 water/bleach and 1/4 cup of dawn liquid soap is really the best, while bleach is toxic, it is less than the toxicity of regular weed killers... why? Because clorine bleach dissipates within 12 hours. It does not harm the ground water. It does not harm the soil, you can go out the next day and plant right on top of the place where the weeds were the next day. :)
Bleach - not so much! Vinegar will work but it is not selective. Anything you put it on, it will kill. Boiling water or steam will work as well, but be careful you don't get burned yourself!
You have to be careful with bleach because it will melt some plastic containers. For instance, if you are using a weed killer sprayer traditionally used for chemicals like Round Up or such. Bleach may destroy the plastic rendering the receptacle useless.
Agree with the vinegar route. We might try it this year, as our dandelions are already out of control.
Bleach is not good for the environment & will get into the groundwater when you use it to kill weeds. You might try vinegar.
Can you tell me about bleach as a weed killer?
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)
