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.
