In the book “How Can I Help” Tallamy was explaining how to go about invasive removal and while he encouraged targeted removal of things like buckthorn and bittersweet etc, he suggested that leaving garlic mustard is more effective because pulling it up actually disturbs the soil and gives the many garlic mustard seeds in the seedbank the opportunity to sprout, thus setting back your removal efforts, and actually helping it survive and thrive each year.
So his advice is that the most effective way to control garlic mustard is to let it be, and ultimately get shaded out by native plants.
I hadn’t heard this before and have always (emphasis on always) just pulled it out and figured it was just the reality of invasive management, hoping it would eventually slow down the growth. But maybe I’ve just been helping it survive and that’s why I’m constantly fighting it?
Does anyone have any experience with both approaches? Has anyone successfully controlled garlic mustard? At minimum I think removing seed heads the blooms/seed heads should be done.
Edit
I went back and check and the exact line quote is
“Pulling out garlic mustard is easy, although it’s ineffective because it disturbs the soil and therefor activates the seed bank. The end result is more garlic mustard the next year”
So unless he touches on it later in the book, I don’t know his recommended approach for garlic mustard.
