We have a new invasive sourge, called Garlic Mustard that is a rampant grower. I had never heard of it a couple years ago, now it is all over my garden. One thing I noticed though is that it seems to have colonized patches that were heavily weeded last year! (Nature abhors a vacuum?) Whereas areas that were heavy with ground cover, and other weeds were spared. I will include creeping charlie as a ground cover and it is beautiful this time of year! Might as well let it grow to keep out garlic mustard.

Had an issue with garlic mustard as well. I eradicated by pulling the plants. Didn't help that the neighbor downwind didn't bother. Noticed a couple weeks ago that the mustard has been gone for a couple years now... then I saw a solitary plant in the neighbors yard....

I think garlic mustard seeds must need light to germinate or something?

We cut back a bunch of thistles and honeysuckle at the edge of our woods, and the ground underneath the honeysuckle was completely barren - until the next spring when it became absolutely covered with garlic mustard.

So your creeping charlie is only a temporary solution Hilarious!

As someone who has lived in garlic mustard territory for decades, here are tips:

-The first year from seed it is usually a short rosette with no flowers. So you have an extra year to pull it before it spreads.

-It pulls easily, but the flowers will still ripen to viable seed on an uprooted plant, so don't leave them lying around.

-It is one of the first things to sprout in the spring, so you can hit it with a non-selective herbicide before your other plants have sprouted if that's part of your gardening strategy.
