I've not heard of a duck pot.  Got a picture?

I've got a smaller (6" outer) tall squarish pot picked out for this tree.  Peter suggested this larger (10" outer) pot to allow the roots more room to grow and mature.  I like the idea of multiple options, so I might be tempted.

Hi Matsu, I love reading your posts and seeing your trees...they are awesome!
Regarding this exposed root jbp, could you please explain/elaborate on the double colander technique used in the earlier stages of developing this tree on page one of this thread?
I assume that it has something to do with root development?
Thanks in advance, Dario.  8)

Same idea behind the cut seedlings.  To allow for quick drainage, allowing more water/fertilizer to be pumped into the tree, shortening development time while maintaining a fibrous root system.

MatsuBonsai, so you repotted before the roots grew threw the colander?  It's a great idea!

 So u just put the roots in a bottle (soda bottle?) with river rock? I'm guessing u cut the bottom off of the bottle right to let the roots still grow in the soil?? Oh and why did u have it potted in 2 pots? What's the purpose For that?

Top and bottom off of the 2-liter, to produce a tall-ish column, then that into a small pot with bonsai soil.

The double colander method has been around for a while and documented in a few places (Kindai Bonsai, Bonsai Today, Pines book, etc.).  A full growing season in 1 colander produces repeated air pruning and division of the roots.  Into the 2nd colander in Fall to increase soil volume and give the roots a chance to continue growing out some, without having to disturb them with a full repot.  I also feel it gives the roots a little added insulation for it's first Winter in a colander.

On the colander idea, I understand the concept, but after placing in the 2nd colander, the roots will grow thru the 1rst one into the 2nd.  .so when you finally put this in a bonsai pot, seems you'd have to root prune all the way back to the 1rst colander to get it out, thereby loosing any roots established while growing in the double colander setup.  Maybe that's the whole point??

Yes.  Take a look at Frank's TotM at the top.  How long do you suppose the roots are in that tiny pot?  Would you think anything inside the 2nd colander would be useable in a final bonsai pot?  It's a process.  You must provide enough room for coarse/strong growth, then cut back and regrow fine.  Rinse.  Repeat.

Now I got it...makes sense.  Thanks!  I need to try this technique next year on something.   I'd learn a lot about the plants growth rate, healthiness of the root system, and much more intensive fertilizing than I've done before.

Hi Matsu/John, and thanks for explaining the double colander approach! I have since purchased the Bonsai Today Pines book and I am now up to speed in terms of understanding that technique.
It has been a while and I am really curious to learn how your exposed root jbp is coming along?
Thanks. :)

It's doing really well. It looks like a little fuzz ball at the moment, after decandling this year. I'll try to post photos on the next day or so, as the kiddo allows.

Even went through the trouble of pulling the clover out of the pot for some updated shots.

That looks great John! Good growth after decandling.
The second pic really shows off the exposed roots well  ;)
At what stage will you do some fine wiring of the branches? Or is it all about development at this stage?
Thanks for updating, Dbs.
