That is the million dollar question.

What is a good way to permanently remove Allium vineale L. from the garden
and lawn?

The plant is also a serious pest in grain fields.

Just digging the plants out doesn't work because there are always a few
small bulbils left behind and it may even actually help the plant to spread.

The same is true for Ornithogalum umbellatum L. and Ornithogalum nutans L.

I have these annoying clumps of onion grass that pop up randomly all over
my
yard. Oftentimes when I try to pull them out they break at the soil level
and the onion bulbs stay intact underground and regrow. They seem to be
very
hardy. Any suggestions on how to best get rid of them?
