I haven't had a problem with it being too acidic.  My iris did much better
this year without the competition from the grass.  The vinegar also did not
bother the roses, though I avoided a direct dousing to the leaves.  I was
thrilled to see it work like magic on the White Top.  I try hard to avoid
heavy chemicals for multiple reasons, but one year I relented and used
Roundup on our grass weeds and on some White Top.  Neither were affected
much and the grass came back as if it had been fertilized.  Not so with the
vinegar.  The whole experience was very frustrating as I have tried to stay
organic, but these weeds have begun encroaching on my vegetable garden so
not only did I not kill the weeds, but now that part of the garden is not
organic.  My conclusion is that the notion that there is no residue from
some of these chemicals, such as Round-up, is incorrect.

We allow a neighbor to use one of our fields for his cattle (keeps the fire
hazard down for us) so he sprayed some $400/gal poison on some weeds out
there and this year they thicker and greener than ever!  I have not bothered
to try vinegar on them yet, but I doubt they would respond with lush green.

Our grass is not lawn grass.  Ours has roots that will strangle anything and
boar right through the iris.

So how do you "fix" the soil after treatment?

If you don't mind multiple applications, vinegar works very well, even on
very difficult weeks such as White Top.  The roots depend on the above
ground plant for food, if you spray the plants with vinegar you are
depriving the roots of their food source.  As I said, it may take a few
applications, but it really does work.  Where I had areas of only "weeds" I
just took a jug of vinegar and sloshed it about.  Many plants, thought of as
weeds, especially grasses, like an alkaline soil and by adding vinegar, the
soil will become more acidic thereby making the growing environment less
friendly.

Yes, Dan, there is/may be an issue with bees with all this poison.  
This is
my first year to use any of these chemicals (other than Roundup), but the
bees have been long gone.  :-(  Not just honeybees, but all pollinators are
a lot scarcer here than years ago.  Lots of diversity in what's left - all
sizes and shapes, mostly various bumble beeish looking things, but also
various wasps and little bitty unidentifiables.

Shaub, have you tried black plastic to kill mugwort or Rumex?  If I abandon
this section of row, I think I'll try it rather than repeated spraying.

Lambsquarters is a totally different story.  I wouldn't want to get rid of
it entirely - too good to eat!  Tho a bit of a nuisance to strip off the
leaves.

Sheep sorrel is tasty too, but a tiny bit of it goes a long way!
