Whenever doing mechanical removal, especially with rhizome roots, you’re not gonna get them all. Don’t focus on that either.

They are like a battery, storing all their energy in the roots for winter and shooting back up during the growing season. If you remove the bulk, you’re robbing the plant of a lot of battery, making it less able to pop up.

You’ll have it come back. But in smaller amounts, which you can just hand pull as they do, eventually totally starving it.

There are certainly ways to find more roots, or times to pull (like rain or after it grows up) or other methods (like a foliar spray), but these all cost more time or include using poisons in your garden. Instead, just dig it, pull as it crops up, and see how it goes. It will likely be enough for less time and let you get into planting stuff.

Also bear in mind: your garden soil also has a seed bank ready to go, so once spring hits you’re gonna get all kind of stuff growing there. If you’re planning to grow your own stuff (food plants or native flowers), then you’ll want to plant those partially grown after you dig, use a mulch for a year or so, and keep weeding. Eventually your planted plants will establish and inhibit other plant growth.

It really is. I’m not sure we can ever be permanently rid of them too.

Growing food plants to eat, yes, the point is to eat.

Growing non food plants, the primary purpose is to support your ecosystem. Bugs pollinators birds etc. They rely on native plants only, and need them to survive.

Beyond that people also like the look of flowers and having them grow or thrive over time.

Good on you for not willfully growing something invasive or non native like bamboo (assuming it’s not in your native range)!

Fuckinnn black locust. You’re talking about places off your property right? Rough.

One thing is spreading awareness that non native plants are bad and invasive plants are majorly damaging. I think focussing on native plants in someone’s home is a great angle. Gardening is something actually in people’s control and thus something they would be willing to consider. Notable points I try to get across:

• your local amazing bug (e.g. monarch butterflies) will all die without the specific native plants they need to survive
• pollinators love native plants more than non native
• Native plants are far more interesting than whatever you get at the garden store for looks
• Natives are dumb easy to maintain. Especially if ppl just buy partially grown ones. Just help it establish, in mostly the right area, and they will thrive
• It’s good for the environment. Non natives cannot support our ecosystem and actively damage it.

Beyond that? You’d have to also start specific campaigns against specific invasive plants and go do group attacks on those plants. Your local green organization will usually be good for organizing and getting volunteers, as well as navigating where you can actually go. It’s a big effort and a lot of work, especially for such noxious plants like full grown trees. But it can make a difference over time

Is it a small enough patch that you could dig it all out? Mint spreads through rhizome roots, so if you dig out most of the roots, you’ll be able to easily manage any new roots. It’s also just preferable to the poison methods when possible
