Please don't plant bamboo
Since moving into our first ever house my wife and I have spent an inordinate amount of our time outside working on removing a really horrific Japanese Knotweed infestation on our land.
Thus far we've only really been able to clear out the areas around the corn crib and the koi pond, but my god the amount of variation that's been able to grow in just a single year after doing most of that clearing is astounding. The majority would probably rightfully be called weeds, but their natural and native weeds, and are having a whale of a time competing with each other for dominance and resources.
Every single one of these areas previously had a single plant, the Japanese Knotweed. Below are a few growing around the smaller koi pond.
The rest of these are arrayed around the corn crib.
I'm desperately hunting for a picture of what this all looked like before, but here's a generic image of Japanese Knotweed, imagine this all over.
It's just miserable. If you're ever considering planting any form of bamboo because you think it'll thematically fit a koi pond, or that it's just pretty, fucking don't. It grows through rhizomes that dig down up to six feet (2 meters), and then shoots out in all directions, creating new rhizomes along the way. Whatever precautions you believe you've taken to contain these plants to a single pot or area, believe me you've failed. Bamboo does not belong here, and the variety flora that was able to claw its way back in such a small area of my property is testament to how devastating bamboo is when introduced to a region it doesn't have any reasonable competition.
Just don't plant it.
