it can also easily cover large areas, way more than you could try to eat. and yeah, when i was a kid we pretended that it is bamboo, but it did not help to eradicate it.

I created and managed two huge invasive species surveys in Kerry Ireland. We did around 2000 kms documenting Japanese knotweed on roads and around 300 kms of rivers and lakes documenting 9 alien invasive plant species. Some species like Japanese knotweed, Himalayan Balsam, rhododendron ponticum and crocosmia were the most prolific. It is difficult to imagine how we could possibly eradicate these species or even get them any way manageable. This was in 2017 and at that time we found just three skunk cabbage plants, which would have been easily eradicated, but now it has spread I am told to a great many other places. Unless we ban all imports of plants we are going to have far more problems than the 9 species we surveyed. I have a small garden for the past 7 years and it was over run with three cornered garlic. I diligently dug up all the bulbs I could see every year, some are very tiny, my husband resorted to spaying, but 7 years later I still find it coming up. So on a national scale I cannot imagine if there is a solution unless we brought the army in to deal with it on a permanent basis. I expect nature will sort it out in its own way. We may not like the results though.

You need to be very careful with Japanese knotweed. Disturbing it without eradicating it is not a good idea. It can root from the ‘knots’ on the stem. I’ve done it in an experiment. This is why it has spread so much along roads from hedge cutting and scraping. Check your garden where you threw it to make sure no bits are left.

there are apps and websites where you can report invasive species sighted depending on where you are located

I threw it over the fence onto the stones behind the shed and later picked it up. Parts above ground decay on the compost, roots have to descarded or burned.

Depends. It could be a case of killing it or just leaving it alone.
