Does anyone have any suggestions for killing wild onions? I have tried many things and they just get worse. Digging them up, works I know, but I have a lot of them in my 2 acre lot.

Both wild onions and wild garlic prefer to grow in acidic soils that are low in organic matter. Applying lime to the soil will increase the organic matter and change the pH to levels that are inhospitable to wild alliums. Be careful to not apply lime near acid-loving plants such as rhododendrons or azaleas.
If you are not opposed to using chemical herbicides, look for a post-emergent herbicide that can be applied to the wild garlic or wild onions. Do not use a preemergent herbicide as this will have no effect on the underground bulbs. Before applying an herbicide to the wild alliums, it is helpful to mow the plants to rough up their foliage and increase their ability to absorb the herbicide. Once the herbicide has been applied, do not mow again for at least two weeks
Par III. You can usually purchase this or something like it at your local feed store. Do not waste your time with Weed-B-Gone because the active ingredients are such a small percentage of the product that you will have to buy it in bulk (which is the point). 2-4,D is what you are looking for. Your yard will look like a golf course in no time.
The old timers say to cut your lawn on a full moon when the onion are growing ( in the day time ). This is suppose to rid your yard of wild onions.

I love these things. They fill my flower garden up with the little white flowers. They also help with the weeds. Jenny

Wild onions, though not a horse's best friend does have it's uses besides using tops like chives. They are not liked by most fire ants and they put nutrients in soil. Tilling and then adding Round Up works.

Does anyone know the best chemical spray to use on wild Onions or wild Garlic? I used IMAGE and it did not seem to work, I even doubled the mixing instructions. It is labeled for Onions and I added "blue marking dye". I need to get rid of these before the grass starts to come back strong.

They reappear the following spring and every spring there after-and after- I have never had anything that would kill them- not even a total kill- move is my suggestion- :) You would think a weed killer for onions would get rid of them but they don't. (03/20/2009)

This works fast, safe, and cheap. Get gallons of white vinegar, and give each clump of wild onions a small drink. Too much will just "run off" and be wasted. Now the soil is wet so it will absorb better. Give each clump a larger drink.
In a day or two, they will be flat on the ground. More vinegar may not be needed; but I like to give a last drink to be sure. My idea is the acid kills the roots; so don't bother with the green stalks.
