At least that's a tree. Cutting down a tree is pretty doable, not like Japanese Knotweed, which is fucking unkillable

We have a saying here that applies to Japanese Knotweed: if you can't beat it, eat it.

The young plants have a rhubarb like taste, we made cake with it once.

What do you do with noxious weeds like giant hogweed (Heracleum mantegazzianum)?

[–] [email protected] 6 points 1 week ago (1 children)

Stay the fuck away from those. Phototoxic weeds are no joke.

In all seriousness, there's a list of plants EU nations are supposed to weed. I think they do as much as they can for plants like Giant Hogweed (mostly because they tend to hurt children and people who don't know about their properties)

In the case of Japanese Knotweed, they have basically given up, so it just flourishes everywhere.

Where I live (Ontario Canada) we are overwhelmed with invasive Phragmites. Although they’re edible and can be used as livestock fodder they still dominate our waterways. We don’t really have any farmers raising water buffalo which would be an ideal herd for grazing them down.

Got it. Canada needs a feral water buffalo population.

Or bittersweet.

Honeysuckle is the worst

All of these make my knees hurt from remembering my years in americorps

I'll add eastern red cedar - not a bad tree by any means, but we would cut it out from prairies and hike the material to the top of the nearest prairie bluff to burn it safely in 100°+ humid weather.

Or garlic mustard

There's a smother option but it takes 5ish years of leaving smothered.

There's the roundup spray option, which is probably the most effective currently? It's critical you spray at the right time (after it flowers)

I saw one option of repeatedly cutting it to eventually starve the plant of energy. I suspect there's some specifics there about when it's ok to cut though.
