Bamboo in pots, then not
When you grow a lot of bamboo like I do (30+ varieties) and most of them are running bamboos, the rhizome pruning that I do to control them results in lots of rhizomes to pot up. Especially if I get lazy for a while and some of the plants shoot in areas that they shouldn't.
The end result is that I have a lot of potted bamboos that I keep in a temporary nursery area. The thing about potted bamboos though...
