When is the best time of year to plant bamboo?

Here in the lower mainland of British Columbia and Vancouver Island we can plant bamboo anytime of the year as long as the ground is not frozen. 

In locations that experience extreme winter conditions it is best to plant in the spring or summer. In extreme cold areas, the longer the bamboo plant is in the ground before it freezes the better. 

Generally speaking, if your soil, water and light conditions are average and the bamboo is planted into the ground for 60 days with temperatures above 10 C, it should root in nicely.
