Are There Any Success Stories On Japanese Knotweed DIY Removal?

It is not unusual to find stories of many people who have effectively eradicated the weed, mainly through DIY removal strategies. An example of such a success story is that of the ‘North Coast Land Conservancy’ (NCLC) group, which is based in Oregon’s State.

Its key objective is to create novel ways of approaching environmental conservation within their area/communities.

The Japanese knotweed had gained a substantial foothold on a 2-acre habitat reserve in the Necanicum forest, a habitat for a variety of native plants. The presence of a river within the area made the growth of the Japanese knotweed quite fast, and immediate action and to be taken. 

The community, against all odds, used hand-pulling, which is considered less effective than other superior methods such as using herbicides in dealing with the weed. However, the secret to their success was consistency in pulling out the weed to allow no time for re-growth.

Although the NCLC admits to having used limited herbicide sprays where necessary, they attributed their success to hand pulling as a Japanese knotweed DIY removal mechanism.
