Porcelin berry vines elimination
For removal of porcelain berry, hand pulling and digging (before berry production) can control small infestations. You can also use herbicides: glyphosate or triclopyr. The seeds of porcelain berry remain viable in the soil for several years so it can take persistence over several years to get an infestation under control. The berries are spread by birds and other wildlife.
The Maryland Department of Agriculture does have an active weed management program for certain types of invasive weeds, but we do not see porcelain berry among them. Residents have to remove porcelain berry on their own property.
