How to control hog peanut, Amphicarpaea bracteata
Hog peanut is a vine that is taking over a beautiful fern area at my church. I have tried pulling it out by the roots, but to no avail. Is there a better way to remove it from an area where you don't want it to grow?

This is a native vine and is a host plant to various butterfly and moth species. Birds feed on the seeds of the fruit. Consider putting the vine on a trellis as it gets beautiful flowers from August to September.
Otherwise, if you have to remove it, cut the vine at the base and paint the cut end with glyphosate. This is a non selective herbicide and kills everything. Do this in the fall when all the carbohydrates are going back down into the root system.
