I have an old silver leaf vine that I need to kill. Some information about the plant and it's location:
It was planted probably 15 to 20 years ago below a trellis we installed next to our back porch. The goal was to create a screen, which it is has done for many years. Several years ago it began growing under and up through the porch floor. We need to replace the porch (not entirely because of the vine, but it has played a role) and need to fully remove the vine. We don't want it growing up through the porch floor again.
What is the best way to kill this vine? We are not averse to using herbicides.
Thank you!

Thank you for your question, Trisha. I am unclear about whether your use of "silver leaf vine" is just descriptive, or whether you are using it to name the silverleaf nightshade species described here: https://extension.unr.edu/publication.aspx?PubID=4506
We can't provide a specific herbicide recommendation without knowing what weed you are trying to control, but the general information in the above article is applicable. Good luck!

Thank you for your response.
I misidentified the plant. It is the silver lace vine (polygonum aubertii?); you can see a photo of it here: http://plants.sargentsgardens.com/12080004/Plant/1711/Silver_Lace_Vine/
I don't believe it is an invasive species, rather, a plant (vine) that I need to fully remove.

Thanks, Trisha. It actually is invasive, per your reference. Any of the herbicides listed in the article I provided should work, if used per label instructions. Take care to avoid applying it so that it hits any plants you want, especially by applying only on days that aren't windy.
