When propagating tropical clumping bamboo using the division method, most take a whole culm division. For me typically I top the culm at the first set of branches. I've noted lately some sellers lately selling small culm divsions, so in an effort to produce a smaller division that is possibly shippable I'm trying it as well. This brief video shows you exactly what I mean by small culm division.

As always, any questions place them in the comments section and be sure to visit my website for more bamboo pictures and videos.
