How can I control invasive mustard garlic?

Asked September 9, 2015, 12:04 PM EDT

Despite my attempts at weeding, mustard garlic has taken over my 75'x120' garden. Any suggestions on what to do to prepare this spot for further planting? I have found that attempts at hand weeding are futile. I can't keep up with it as the growing season progresses.

Garlic Mustard (Alliaria petiolata) is very difficult to eliminate from an area. The most important tool in getting rid of this pest is persistence. Understand that the seeds can be viable for up to 10 years. It can take several years to reduce the seed bank to easily manageable levels; however, many have accomplished significant control in three or four years. The following links will give you several options to control this invasive:
