    %5 household vinegar will burn your grass, apply on hot sunny days for faster effects.

    The % of vinegar means the % of acid it has. So household vinegar that is 5% means it is 5% acidic. Some organic weed killers contain acetic acid which is the vinegar.

    Horticultural vinegar can be purchased at these sites. At the second one look in the lower right corner under 'Bradfield's other natural products:'

    I was a minute too late to edit my last post.

    You can find other organic products and weed killing products at the links I gave above. You might also find this helpful about maintaining an organic lawn.

    My experience this summer:
    Grasses are tough once matured, but on a hot sunny day, which we have had plenty of, in a well irrigated garden the annual broadleaf is killed with 5% household vineger.
    Perrenial broadleaf - not so much. (Have not yet tried 10%)
    I wonder if the acid in the vinegar helps the blueberries or not. Perhaps it is quickly nutralized as it decomposes in the soil.

    Spraying the weeds inside the drip zone isn't going to be too much , is it?

    If you are looking for horticultural vinegar we carry it and have it available for purchase.

    All you need is acetic acid and water.

    I would suggest you look for a local source of 50% acetic acid and water, then dilute if you need to.

    Alternatively you can order it from a chemical supplier, some will mix it to the dilution you want.

    If you just want to use white vinegar from the grocery store just make sure it states what the acetic acid concentration is.

    As long as the vinegar is sprayed on the leaves of the weeds and doesn't drench the soil you should be fine.

    Most white vinegar in the grocery store is 5% acetic, sometimes 10%.
