Greenbrier… oh boy Greenbrier the stories I could tell you about Greenbrier there’s this one gigantic super organism. I’ve been using as a test subject ever since I started out it’s resisted all of my attempts to kill it here is a list of a few of them
sulfuric acid
Hydrochloric acid
Citric acid
Caprylic acid
Capric acid
Acetic acid
3/4 of a ton of salt
fire [we burnt it to White ash dug it up and burnt the tuber till it glowed it re-sprouted from the same burnt end that was glowing two years afterward]
lye
Concentrated bleach 12% sodium hypochlorite
boric acid and borax
Ammoniated soaps of fatty acids
dicamba
diquat
Triclopyr
24D
imazapar (constant background exposure due to water table being weird) some targeted sprays
glyphosate.
Over the course of 10 years
AND IT JUST WONT DIE
most of the things you saw on this list only slightly browned a few spots on the leaves if we were lucky
we’re gonna try to up the concentrations to see if I can do anything now that I have access to formulations that only have the active ingredients as opposed to the consumer versions which I was using in my past experiments now that my budget is higher and we’re gonna try some new formulations though could you send me a picture of the Greenbrier in question so I can see if it’s the same species as mine??
No idea what this plant is, using AI the picture I get looks like Vinca/periwinkle which is very tuff. Still persists around old homesteads where all the buildings have rooted back into the ground. Will stay green all year even with extreme heat, and are dry from May to Nov no rain growing season here in California. I have been witling back a patch in my yard. Glyphosate sometimes better than others. Lately I been spraying Garlen for misc. broad leaf weeds and it has been setting it back.
But more important some of the tuff weeds are better controlled with a lower dose of systemic herbicides. You can burn the top back and stop translocation to the roots, which is what kills the plant off. |
