How To Get Rid Of Wild Onions?
Q: Do you know of anything to get rid of wild onions except pulling them out?
A: Hand-pulling wild onion/wild garlic has the disadvantage of leaving in the soil the bulbs that don’t currently have leaves. The herbicide imazaquin (Image for Nutsedge) is absorbed by the roots of wild onion/wild garlic and therefore gives more complete control. A suggested application technique is to spot spray the herbicide on and around a clump of weeds, then drench the area with one pint to one gallon of water. The chemical will be carried down to the roots for quick absorption.
