I'll post a tree picture a little later...
Here's a tree as promised...
My Austrian pine had been growing in the black plastic pot for years. When the bottom of the plastic pot broke, I set it in the wooden base temporarily. I recently built a full wood box for it and slip potted it into this to get away from the emergency rescue situation. This new box has runners on the bottom to help drainage and make it easier to move. I also built it too tall, so the top row of boards will be coming off.
I was able to change the planting angle this time which helps the design I think. I plan to bring that left branch down a bit.
As it has grown the last year or two I've noticed that the top (Oregon Green cultivar) is outgrowing the base, giving it reverse taper. I'm not sure what can be done about that at this point though. It wasnt so noticeable before.
