Running bamboo is notoriously fast spreading and difficult to remove. What keeps its population balanced in the wild, and prevents it from crowding out the competition? I tried googling, but was inundated with gardening advice, horror stories, and assault / offensive gardening (some of the latter two presumably covering the same incident from both sides). My google-fu failed, I couldn’t really find any info about natural population controls of running bamboo in the thicket of tall tales and gardening advice.
Kudzu won’t grow where I live either. I’m not actually sure what the equivalent would be. Dandelions are the most unstoppable plant I can think of. Creeping bell flowers are maybe a close second.
