I have onion grass all over my lawn and the lawn reeks of onion when mowing. I have been told that pulling them up should NOT be done because if you accidentally leave even the smallest part of the bulb it will regrow and spread rapidly.

Is this correct or should I religiously pull them as I see them grow? The soil is a very heavy clay soil and trying to dig them out meticulously, some of the bulbs are absolutely tiny and it would be extremely time consuming.

Many years later, but just came across the same issue.

I keep finding the same remedies

  1. Mow regularly to prevent onion grass from going to seed.

  2. Remove the entire bulb. So long as any part of the bulb remains, onion grass can regrow.

  3. Pour boiling water. Scalding hot water will kill just about any plant. Target with specific herbicide after mowing.

  4. Target with specific herbicide after mowing. Herbicide use should be used as a last resort.

Above summarised from What Is Onion Grass (Allium vineale) & How To Get Rid Of It. And I am not associated with the website.

So, I guess keep mowing regularly and keep pulling them out. Even if you leave a tiny bulb, it is still better than not pulling the rest out.

  • As stated in the question, "I have been told that pulling them up should NOT be done because if you accidentally leave even the smallest part of the bulb it will regrow and spread rapidly". Yet, you are suggesting the opposite with the guess that it is better than not pulling them out. The first suggestion helps slow the spread but doesn't stop them. 2 reiterated my point, 3 is possible but an expensive resolution with today's fuel prices, 3&4 will kill the lawn too would it not?

  • If you don't dig it up, it's in the ground already and is growing rapidly. So, take your pick
