Great progression series. I do have a question about the pot. Is it made of the mixture of newspaper and concrete? I had considered making some but I was concerned about the interaction of the cement and the roots of the tree. Is it harmful to the root system?

Yes, this is made of paper and cement. The pot will have to be totally dried out. That's about it. It may be helpful to put it under water for a few days to wash out whatever wants to be washed out. I can see no problem from the cement.
