Vinegar as a Plant Killer
Name: Kristin E.
I have learned that I can kill weeds with vinegar. Does
the vinegar act as a systemic or does it make the soil so inhospitable to
plants that nothing will grow?
Vinegar can reduce the pH of soil sufficiently that many plants will not
Apparently the acidic content in the vinegar burns the plants. Although
will acidify the surrounding soil somewhat, vinegar is a weak acid, so the
soil is expected to return to its normal pH after a few days or so.
The following should be helpful:

You are correct, the vinegar will make the soil inhospitable to plants.
The low pH of the vinegar will disturb the ability of the plant roots to
draw up water and the mineral nutrients needed to survive.
