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.
probably because it needs to be artificially moved elsewhere, and unless it moves in large enough quantities it’s outcompeted
Himalayas and Siberia stops natural expansion, farmland essentially corner it, everywhere else it could grow is also already occupied
