[MAIPC] Garlic mustard disposal

Sat Apr 17 05:52:29 PDT 2021

t according to Dr. Berndt Blossey, a Cornell University conservation biologist who specializes in invasive plants, pulling up large swaths of garlic mustard is not only futile, it is worse than leaving it alone. It’s worth echoing: When well-intentioned people rip out this stuff, it actually prolongs the infestation period because the plant is self-limiting (more on that below) if undisturbed.  Also, these mass garlic mustard-ectomy events do more damage to the ecosystem than the target species itself does.

>> 
>> 5. Prioritize removal of garlic mustard that grows along the trails to minimize the spread  of seed to other areas. If you weed whack the edges of your trail, make sure The garlic mustard is pulled out first. 
>> 
>> 6. We have created a dumping pit in an old foundation where we dump the bags every year.  Nothing spread from there.  You can also leave in the bags until later in the year or next season and the plants will die inside the bag... much less bulk that fresh plants.

I often pull GM plants and lay them in a nearby well traveled path because they will be trodden upon even if they do germinate. This has been very successful.

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.

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?
