Maggie's Farm

I think the trick is either to yank them out when young, or clip them low and spray the stump with poison.

If you live in the Northeast, your gardens and plantings are, right now, being attacked by the unwanted and unwelcome alien Porcelainberry. In fact, you can see it smothering trees and bushes everywhere.

This aggressive Asian weed vine was introduced as a decorative ground cover, but it is a cancer with the ability to grow 15' or more per year, and to smother anything you have planted. If you pull it up, get the entire root - or poison it.

The birds poop the seeds everywhere, so they come up everywhere around here. Especially in gardens. Their roots are tenacious. If you just clip them, they come back twice as strong.

As its leaves demonstrate, it is a member of the grape family and it can be confused with the native wild grape, which is a much less aggressive plant. You can read all about Porcelainberry here, and about how to try to get rid of it.
