Educate Yourself and Neighbors

To tackle Japanese knotweed, start by educating yourself on its identification. Japanese knotweed starts as red asparagus-like shoots, which become hollow, bamboo-like stems.

Its distinctive green heart-shaped leaves are a giveaway that you have a problem on your hands. These leaves grow on stems that can reach up to 10 feet tall.

The sooner you detect a new population, the better chance you have of successfully managing it. According to Tom Lautzenheiser, a successful management effort is more likely to happen when detected early.
