If You See Japanese Knotweed and Garlic Mustard, Along the Path, KILL THEM!   6 comments

Honest to goodness, go apeshit, take out your frustrations and do the environment a favor, before they flower and go to seed!  Both Japanese Knotweed,  Polygonum cuspidatum, and Garlic Mustard, Alliaria petiolata, are tenacious, horribly invasive species, choking out many lovely natives, at an alarming rate.  Many states have disposal regulations for these species, it’s that bad.  Sure they both, also, share a short window of edibility; which, here in New England, is right now.  Although, a good deal of the Knotweed is past, the Garlic Mustard shoots are at their edibility peek.


If I’m out, tool-less, and come upon Japanese Knotweed, it gets stomped!  Sure, clippers, a machete, and bush-hog would all be helpful, but, my feet work, too!  And, I try not to carry all that much, all the time!

After I snip the tender young shoots, Garlic Mustard gets yanked.  Thankfully, they give little, if any, resistance.  No seeds will form on these!

Remember to wonder off the beaten path, while gathering.  Never forage where poop grows!

Thanx for stopping by.  See you next time.

Just click on any photo to enlarge.

  1. I went out with a group yesterday at the Boxerwood Garden and Education Center in Lexington, VA and the eight of us spent a couple of hours pulling out garlic mustard plants by the handfuls. We made a big dent in it, but we needed 100 more of us because it had spread unchecked for years!

  2. So-called invasives must be handled wisely. Although it’s a big problem in some human-disturbed habitats and along riverbanks, where floods cause the disturbance, I haven’t seen Japanese knotweed increase in the Greater NY area since I began leading foraging tours in 1982. And while garlic mustard is a big problem in The East, it’s a waste of conservation money to try to eradicate it in the West because it’s not fire-tolerant.

    Recent ecological studies show that each “invasive” must have its impact studied individually to determine whether or not it’s a real threat, where that is so, and which species it impacts. Japanese honeysuckle, for example, takes over habitats and displaces native plants. At the same time, its berries provide food for birds that are in decline. As the bird populations recover, they spread the seeds of plants that are also in decline. So invasives are not the black-and-white issue we once thought they were.

    • Agreed, each species, in every locale, should be considered, individually. Here, in Mass.,from the Berkshires to P’town, Japanese Knotweed is more of a threat than Garlic Mustard. The Knotweed Plague lines every highway, river, stream, lake, and bog, threatening all in it’s way. But, Autumn-olive, also considered invasive, is a welcome treat. If anyone wants Knotweed, PLEASE, come and get it!
