If they're flowering, don't pile!  Moisture of pile will allow some plants to live and produce viable seed.   I've seen single plants pulled and left on trails, and there is enough energy that the plant wilts EXCEPT for the flower portion the goes upright and uses last resources left in root to produce seed.

  What we do for long hikes is we pull the plants, then cut/rip flower heads and put in bag.   The root portion we leave to dry out and die.  I sometimes hand them in shrubs and branches to make sure they dry out and don't have a chance of re-rooting.   Leaving the roots and basal leaves really reduces the weight of your bag to carry out.

One idea, in order to avoid lots of bulky heavy bags of garlic mustard that must be hauled away and tossed in the trash, is to have all volunteers make one big pile of the pulled plants, preferably in a spot where the seeds won't be washed into new locations. That way, if any seeds do mature, they will be concentrated in one location, which will make subsequent workdays easier. Not ideal, but better than generating loads of trash.

Hello everyone,
Does anyone have experience pulling garlic mustard and piling it on site? I am having a large volunteer event to pull it, and am limited in how much we can cart out. I'm hoping if we pile it up it will decompose and not reroot or spread. Has anyone had a positive or negative experience if not bagging and removing?

Thanks!
Colleen
