Question: Do you have any suggestion that might assist me in the removal of wild onions from my lawn.
Answer: There are no pre-emergent controls for wild onion, but there are herbicides that will work during the growing season. If you wish to go this route, check with a garden center for the proper material for your area and your grass variety. You can nip the problem in the bud by digging out the bulbs early-on. Frequent and close mowing is another control measure. The diminutive onions thrive in heavy, wet soils, so aeration and holding back water may help. We hope that you dont shed too many tears over your problem.
