This ishitsuki came to my garden about 20 years ago after a major quake threw it to the cement smashing the pot and breaking many branches. Wish I'd gotten to it before the roots were formed, Oh well. Still waiting for some berry's to green up, but not many this year compared to last.

Now I know why less berries! I poked my head out the door this morning and this was sitting on this pyracantha plucking the berries. We are not amused. I had two instant alternating reactions: camera-BB gun-camera-BB gun. these are large birds. I'm glad the rock was there or it would have been sitting on the branches.
Kalij pheasant.

Bruce, wonderful transformation. You have greatly improved the tree. Well done.

About turface. Potting media debates are endless, I'm not intending to provoke a re-hash of the whole issue. Michael Hagadorn's observation on the properties of Turface are largely correct, but he goes to the extreme on his conclusions. The manufacturer's specifications and use recommendations state it should not be used as more than 20% of the growing mix.

I've used turface for many years, with good results only when it is a minor component of the mix, meaning less than 20% of the total. Most media, when used as single component media have compaction issues. A media that is a blend of different shaped particles seems to generally be superior to single component mixes. As you said, Turface has a pleasant color as a bonsai media, consider using it as a topping to hide the bright white of the pumice.

My standard mix is pumice, crushed granite, akadama if I have it on hand, pine bark, and turface, with the pumice and granite making up the majority of the mix, the other items being somewhere in the 10% range each. Seems to work well. I sift for uniform particle size. Seems to work in my climate. Climate is a big factor also, so different components work better in dry climates, some components work better in wetter climates. There are thousands of different variations on a theme. My choices are based on the fact that I can get all of these from retailers within 10 miles of the house, so if I run out, I can quickly buy more. The exception is akadama and kanuma, both are logistical problems for me to get, I have to plan ahead for them, so sometimes I end up skipping their use due to not being on hand.

Ready availability at reasonable cost is my principal factor for choosing media components once I understand how to use them. 

Thanks Leo, glad you like it. And I completely agree with everything you said.

One more thought on media

Pumice is excellent, one of the few media components that really does grow good roots even when used as a single component media. Nothing wrong with it other than color. Top dressing with a different media for show is one way to handle it. Since you live on a volcanic island, pumice and different grades of lava should be inexpensive to get. Would one of the darker colored crushed lava be available for use as a component or top dressing?

Sure, black cinder  is an option but I still use turface as a top dressing but if I don't remove it after a show or photo it seems to be hydrophobic if it's dry  and makes watering a problem. It's always something with these trees crammed into little pots. ::)

Pumice was not available here either but a garden center was kind enough to bring some in. You might try asking. Black Gold was the brand I was using. Very clean and screens to large, medium and fine.

Do you have any other info on Black Gold?  Could you post a picture of the bag (and a smattering of the pumice)?

Sure. Here's the 3 sizes I'm able to screen with very little fines.
