Thuja occidentalis progression
This is the first large Eastern White Cedar I collected. After four years of growing, the foliage mass was finally ready for some real work and this year it has gotten a lot of attention. In July it was thinned and roughly wired, and today it received its second and final thinning for the year.
I think this tree is actually two separate trees that have been growing together for a long time. The second trunk on the right is growing towards the back, and I’ve always toyed with the idea of removing it since it seems out of place. David Easterbrook and Marco Invernizzi both advised me not to remove it, and now I am starting to understand why. That secondary trunk provides much of the depth of the tree and without it I would be left with something very two-dimensional.
It will be difficult to find a traditional bonsai container that works for this tree. I’ve got some ideas for the future planting, but it will not be easy to pull off. The final planting will determine which of the large jins I end up keeping, if any. If I can sort it out next spring, this tree might be ready to be shown in Fall 2015.

As collected Fall 2010. Note the fist-sized rock lodged in the base of the trunk which had to be cut out with a die grinder.

Summer 2012, completely barerooted to remove the toxic muck and repotted into a much smaller grow box.

Summer 2013. Some major pruning and coarse wiring was done this year to open up the foliage and set the basic structure of the secondary branches.

Today after another round of thinning and minor adjustments. There is still a fair amount of floppy foliage but that is gradually being replaced with tighter growth or removed entirely.
