>> So the two-fifth sections were around 6 inches diameter. They did (and are doing) fine. Any section with less than eight culms died. Not sure how my climate (Minnesota) factors into this.
Thanks!
That almost doubles the number of divisions I can take.
However, the person I was going to make the hedge for now is unsatisfied with how long it would take to fill in. Also, her park management has promised to put "something" back where they knocked down the nice hedge. She plans to buy enough tall plants to fill in whatever the park leaves open.
The original "reason" given for ripping out a nice hedge was that "it blocked the line of sight for cars driving around a corner". I use quote marks because the park has many similar corners just as blind.
Anyway, this means that I can divide mine in the spring instead of right now, and I can keep the divisions instead of giving them away.
I want to take that bed apart anyway, so I can line the concrete paving stones with plastic to keep the corners and edges from drying out so fats. Also make one wall taller to deepen the bed, and replace the soil with something more organic and less clayey.
Now that I know this bamboo likes shade ("2" on a scale of 5 where "1" is "full shade") I have more spots where I can plant it. And I might make up a few pots for mobile bamboo and for giving away.
