Killing driveway weeds with bleach. Dilute or not?

+12
Answered

5% household vinegar does nothing to my driveway weeds.

I’m going to spray bleach on them. I’m thinking I should dilute it and add some liquid soap, for a surfactant.

If I dilute it 50%, is that too much?

    Hi Lifestyles: I'm not sure bleach would be good. Here's what I use and it works great for me:


    Homemade Weed Killer:

    The recipe I use is:

    1 gallon of white vinegar

    2 cups of Epsom salts

    1/4 cup of dish washing detergent, like Dawn.

    Mix the vinegar and salt until the salt is completely dissolved.

    Mix in the Dawn until mixed well, but not all fuzzy and sudsy, sort of swirl it around.

    Put in a spray bottle and spray the weeds liberally, in the morning after the dew has gone. Then, by evening the weeds should be dead or on their way out. Don't spray anything you want to keep or it will die too. I have used this and it works quite well. Also, it's good for making an edging as it kills only what it touches. If you have something like a piece of cardboard, hold it up and down, edgewise, and spray the area you want as an edge. Just be careful not to spray your flowers and/or bushes. Good luck


    WEED KILLER WITH DAWN

    1 gallon white vinegar

    1 cup of salt

    1 Tbsp liquid Dawn


    Combine ingredients and put into a spray bottle and spray the weeds at the sunniest time of day.


    This mix is very effective so make sure it doesn’t spray on something you DON’T want to kill.


    Good luck

    Purchase the vinegar from a home store or hardware store where you will find a much higher percentage marked on the bottles. It will cost more, but is much more concentrated in strength.

    Here's what we use and it really works. Sometimes have to hit the weeds twice, but I like there are no chemicals in the recipe

    I use 1 gallon of vinegar, 1 cup of salt and 1 tablespoon of Dawn. Spray on weeds in the morning on a sunny day. The sun seems to help cook the weeds.

    Be advised that using bleach to kill weeds is likely to raise your soil's pH level. Growing plants, shrubbery and other types of greenery may be made more difficult with raised pH levels. Do not mix bleach with other household cleaners. Mixing bleach with vinegar is especially dangerous. Using bleach to kill weeds may affect insects in your garden.

    I would not use bleach especially since you have used vinegar - bleach and vinegar do not mix well and can be toxic. Buy a weed killer in a spray bottle and use that.

    A little variation on the pinkfortitude recipe is 1 gal white vinegar, 1 cup salt, 1/4 cup dish soap. Put it in a pump up sprayer and spray directly on weed near the ground. Use the salt in the mix if you don't want things to grow there like flowers. Delete the salt and just use the vinegar and dish soap.

    Since 30% Vinegar costs $20-26 a gallon (Home Depot was 20), it’s cheaper to buy real weed killer for the driveway.

    I did do the cheap vinegar, salt, detergent and added 16 Oz of Pinolin (spelling?).

    It works fairly well.
