On the first tree I bought the tree in 2009 from Ian Price of Lone Pine. The tree was in a heavy collar five gallon can.
The tree was put into a cut down five in 2012 after the grafts had taken. The sides of the can were about 5 inches.
The tree was put into a colander in 2014. at this time I tried the Yamafusa and it was still too large. Many of the largest roots were cut back hard and carved on the bottom to allow rootage. The sides of the colander were about 5 inches tall also.
In 2016 the tree was finally starting to get a manageable root system due to the colander and was able to go into the first ceramic container.
I entered the tree in a display contest during this time.
And today Jan. second 2017 it goes into it's purchased for pot
