how do you kill wild onions in your yard?
Answers:
The only way to get rid of these is to dig them out .Most commercially available weed killers will not get rid of them.Dosing with weedkiller, from personal experience will only yellow the above ground foliage, even after two or three applications.The following year you will have twice as many to deal with .The good news is that they are not deeply rooted.
