How can you kill Japanese anemone?
The Gardener’s Answer
Hello, Marie: Fall blooming, Japanese anemone can spread after they have become established but typically they are not aggressive. In the States, these plants are not considered a weed and many hybrids are sold in garden centers. This may not be the case in France, but the hybrid ‘Honorine Jobert’ was developed in France in the 1850s and is still very popular today. So, to answer your question, these long-lived perennials can be removed from the garden by digging up the plant as well as the fibrous roots. This would be the most environmentally conscious choice, but you can also kill them by spraying with Round-Up or any herbicide with the main ingredient being glyphosate. If the reason you do not want them has nothing to do with them being aggressive, you may check with your gardening friends to see if they want them. They may even come and dig them up for you.
