Garlic Mustard weed has taken over my yard - has anyone had any luck getting rid of this stuff?

It came up out of nowhere this year. I read that it's a biennual so it was around last year but just not noticeable. We are in the process of clearing trees and brush from our yard and this has popped up in all of our newly cleared land. This is not my yard but exactly how mine looks right now.

Re: Garlic Mustard weed has taken over my yard - has anyone had any luck getting rid of this stuff?

  • around here people just pull it out, roots and all. We have a lot of "garlic mustard pull" days are our local parks. You can eat it, actually.
  • Hi Wendy - yep, it pulls out pretty easy but honestly, I think it will take us 3 years to pull it all up - it covers about 1/4 acre! maybe I need a weed pulling party!

  • Put a add on freecycle that says free garlic mustard weed- must harvest your own and your address. Maybe that would work Wink
  • i am a lurker here but I have the same issue.  Last summer I pulled and bagged about 5 or 6 garbage bags full and barely made a dent.  I hate doing it, but I got an eco weed killer and it worked great!  This years garlic mustard is only where I did not spray.   Some weekend I will have DH spray the rest.

    beth - would you mind sharing the name of your weed killer? from what I read online nothing works all that great. did you spray it while it was tall or in its first year?

  • Ah yes my arch nemesis garlic mustard.  Clearing woods = exposing thousands of garlic mustard seeds to sunlight.  Did you know garlic mustard seeds can last for up to 10 years before they need to germinate?  That means you have a minimum of 10 years of pulling on your plate no matter what you do.  

    Spraying works but it's only recommended in the very early spring when nothing else is up yet.  Otherwise when you spray you are killing every other plant out there no matter how small.  You can also mow but that doesn't solve the problem it only delays them from being able to seed all over the place which happens around June.  For now start pulling.  Pull right after it rains and get down low so you get the bent taproot.  A V-shaped weeding tool can be helpful if the soil isn't loose enough.  After you've pulled them up step on the soil to pack it back down flat.  Disturbing the soil just allows more garlic mustard seeds to germinate.

    We pulled 10 garbage bags full of garlic mustard last year and pulling seems to be the only thing working for us.  The first year plants are small and inconspicuous with two heart shaped leaves just like the second year plants.  I pull them out of flowerbeds but in the woods we wait until they are second year plants and easy to identify and find. 

    So have fun.  Go out every night and see how many you can pull in one spot.  Get your daughters into it and make a game out of it.  You have a lot to try to get before they seed in June!

  • Foxi - this is so depressing!! I will not be able to pull it all by june!!!!

  • Sorry.  Why were you clearing the woods anyway?  Are you going to use it for something?  How did you clear it and did you kill all of the native plants at the same time? 

    We expanded our yard slightly a few years ago to make a fenced in dog area because the size and location of our backyard made it difficult to fence in.  The first year we had a lot of garlic mustard but we hadn't killed all of the native plants so it wasn't a solid sea of it like it looks like in your photo.  I pulled and pulled for days on end.  I started in one small area and made sure to get every root.  I didn't get to all of it so I went around and cut the flower heads off the ones I didn't have time to pull before they seeded.  Then I planted as many spreading groundcovers I could get my hands on.  Vinca, all of the fun varieties of ajuga, irish moss, real moss, sedum in the sunnier areas, creeping phlox, etc.  Big leaved groundcovers shade the soil and tight groundcovers are hard for things to grow through.  The second year I did the same thing (lots of pulling again).  Now the third year I only had to pull a half a bag or so in the dog yard.  I was really surprised how little there was in there this year.  In the woods however its still pretty bad.  Eventually other plants should start filling in but we're considering starting to plant some native plants in the woods to help control the garlic mustard.  But that could really get expensive so we'll see. 

  • We are clearing our yard in hopes of expanding and fencing in one of these years. There really wasn't much in the way of plants where we cleared, just tons and tons of brush and thicket.

     I too thought about ground covers but it would be dangerous to do that right now with all the tree/brush stumps.

    I am intrigued by your mix of ground covers. Any chance you'd share a pic?
