Ever wondered just how far out those oriental bittersweet roots extend?
Here are two vines that were carefully hand-pulled to answer the question. Neither vine is more than a couple feet in length above ground, but the top vine has over 6 feet of root length, and the lower has over 8 feet! Given the perennial nature of these vines and the fact that new growth sprouts from the root structure, it's a pretty scary picture. If you pull the vines be sure to get as much as possible, and go back periodically to remove any additional sprouting.
