I've actually tried this, with regular store brand vinegar. It took a couple of days, but it did get rid of a few weeds. Some it didn't seem to affect too much. I used it in the cracks in the sidewalk and the asphalt in my parking area.

Why would anyone want to kill clover?

It's green, looks nice and fluffy, it pleasant to walk on and best of all "don't ever need to cut it, it just stops by itself".

The flowers feed bees.

In fact if you want to abandon grass altogether, you can plant a herb and wildflower lawn. Helps you stand out in your dreary conformist, suburban street.

However I will try vinegar on the bindis and ficus vine (which would probably survive a nuclear strike.)

I have an itty bitty yard, so weeding isn't too arduous. Just thought I'd build on Deb's point-- clover also fixes nitrogen in the ground (I think). I don't know where that leaves you in the clover-is-good or clover-is-bad debate, but I don't worry myself over it when I see it in the yard.

Apparently even household vinegar will kill weeds without harm to some other plants. USDA and some universities have conducted research on its effectiveness. If you use vinegar as a herbicide, take safety precautions as vinegar above the household 5% concentration will burn skin and eyes.

Here are some articles:

I wouldn't ever want to get rid of clover either - I think it's a great ground cover.

I'll try this on my dandelions though (they're a BIG PROBLEM for me!), but I'm skeptical anything can kill those buggers!

Yes it works, especially on weaker weeds (dandelions require multiple doses). However, because of the high acidity of vinegar, it's very bad for your soil. You only want to use this technique on pathways or areas with bark/wood chips.

A better and more soil-healthy technique is to collect leftover (and often free) burlap bags from your local coffee shop, place those on the ground, and cover them up with dirt or wood chips. After four or five years, the burlap will destroy any of the especially noxious weed roots (i.e. dandelions) and deteriorate back into the soil. Of course, you'll still have to do light surface weeding above the burlap.

Finally, I also agree that I wouldn't want to eradicate clover. It's a nitrogen-fixing plant and actually replenishes nutrients in your soil, unlike grass and other common weeds.

Burr clover is terrible. The burrs make a walk on your lawn extremely unpleasant. I've had some success w/vinegar; I've also used boiling water which just fries the weeds but doesn't really harm anything else.

"Seed inoculation: White clover can only fix nitrogen when the proper Rhizobium bacteria are present in the soil. To ensure nitrogen fixation, white clover seed should be inoculated with the right kind of Rhizobia prior to planting."

These folks have seed that has been inoculated.
