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.
Because Japanese knotweed has an extensive root system, it's essential to reach out to your neighbors if they have it on their property. This will help prevent the problem from spreading to your yard.
Disposal Methods
You can dispose of Japanese knotweed at your local landfill site, but first, check if they accept invasive plants and let them know what you plan on bringing. This will help prevent the plant from being spread to other areas.
Never put Japanese knotweed in a compost pile, as the soil can become contaminated with bits that can continue to sprout and spread.
To dispose of Japanese knotweed, you can also pile up and dry out the stems on plastic, before tossing – just make sure they don't re-sprout or get washed or blown away.
Professional disposal is recommended, as attempting to dispose of Japanese knotweed yourself can be costly and may result in regrowth and further spreading.
