Interesting points. I admit to knowing nothing about Bonsai except that they make me go, ewwww, awwww COOL!! whenever I see a nice one.
I was wondering about water logging the roots when I first came across the setup video. I have seen what that can do to container plants with out proper drainage.
Before I posted the link I was looking over the blog, and reading the setup. They way I saw the pictures and interrupted the article I thought he was keeping the water line just below the plastic container the tree is planted in. Its hard to tell from the pictures though. It looks like Felipe is a member of APC, perhaps he will speak up about the design.
The two pictures below somewhat show what I'm talking about.
Also, speaking of Micheal's bonsai and green thumb. I saw the links to the pictures of his backyard in the post titled cool video. All I can say is very impressive. It all looks so nice, and such a natural flow. I was expecting to see Sasquatch sneaking out from behind something with every new photo....lol It was interesting to compare plants from Niko's pictures that appears to be last year, and the new ones from Texguy. That Cypress tree seems to have really grown over one year. I am not familar with the care of such trees. Would you consider that normal growth, or do you think its growing above average?
