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.
Are palm trees not a grass?
Palm trees are monocots and are therefore related to grasses, however they are not grasses themselves. Monocots are a really broad group though. Kinda like saying a certain animal is a mammal. Important distinction but still very broad.
