While experts say they are a nuisance plant, I have to admit that when I am out and about and smell fresh cut grass mingled with the smell of wild onions it is just wonderful. I want to fill my lungs with the smell – perhaps it brings me back to my childhood!
But if you’re one who hates the smell, you can get rid of them. American Lawns says,
While these plants can easily be pulled from wet soil, they usually leave bulbs in the ground and will re-appear in short time. In fact, the garlic produces many underground bulblets that are difficult to remove even when the plant is dug up by a spade. Mulching can help prevent the emergence of these plants in the garden beds.
Goodbye wild onions.
