| Re: Japanese Knotweed versus Aphalara itadori
and we've been cutting it, mostly twice annually, for several years, and it will clearly take at least another five years....
I know a gardener that has Japanese knotweed in the lawn and it has been there for thirty five years being cut every two weeks. Cutting will reduce the plant by upto 98% but will not kill it completely. If cutting ever stops the plant will gradually regain strength and re grow. This is one of the things that make it so successful. |
