1 ga Vinegar; 7% strength
1 c Salt
2 tb Dawn dishwashing detergent *
* This will act as a surfactant and make the vinegar and salt
solution adhere to the weeds more efficiently.
Mix thoroughly, spray on weeds (only - see notes). Repeat as
necessary.
Notes:
Like most commercial herbicides, it's nonselective, not caring
whether it kills weeds or your petunias. Unlike commercial weed
killers, vinegar is eco-friendly and won't harm people, pets or the
environment. Vinegar's only real drawback in certain cases is that
it has no residual action, so new weeds soon arrive. The addition
of salt mitigates this somewhat.
Drench the weeds with the solution on a dry, sunny day. Coat all
surfaces well with the spray. Any plants soaked with this solution
will die within several days.
