Niiiice!
I'm sure my baby likes the constant PNW rain, and I water him in the (dry) summer. I am going to try to improve his drainage when I have time.

Funny, my reading tells me that most bamboo have very shallow roots. maybe the big ones are fussy. I have read about bamboo cuttings and layering, but they talk about how hard it is.
Has he tried during different seasons? I think that, when the tops have stopped growing, the roots are growing fastest. Maybe the roots are most nearly dormant at an unexpected time?
