I think none of the new canes outsizes the largest of the transplanted ones. That will likely happen next year. Some are about 10 feet tall now, so growth is significant.
Even small chunks that I planted, thinking they wouldn't grow, have produced at least tiny canes.
The timber bamboo in the chicken yard does not have new growth yet. I don't know if it will need another year, or is just later to grow.
