Woah lots of interest here from tghe looks of it guys. Let me see if I can answer your queries for you;
1. Jamie, you might want to rethink the 2 trees, 1 box bit mate. The growth you will be getting shortly is going to make it very difficult to manage both trees and repotting will be a proper, well hard job.
an aside to the box your using as well, recently I repoted a couple of trees, one of which was in a styrene box, the other in a black plastic box of about the same size, which I got from the big green shed

. The styrene box was near full of roots while the plastic one had hardly any roots to speak of. Both trees where roughly the same age and had received the same amount of care. While nothing is proved conclusively, it does begger the question.

Very interesting method. One question...how do the trees go with internode length? with all of that super-fast growth, I would imagine the internode length could become quite long.
I only ever grow my trees in full sun. I have not had problem with internode length using this method, but then I am constantly trimming the branches as they grow as well.

Sorry mate, all measurements are 100mm flower pots, so it's 2 100mm pots of B & B.

Spot on mate, I don't think you could keep up with the growth well enough to do any sort of refinement.
jamie wrote:nothing against you graeme i am sure you have had great success but obviously some loss.
Sorry cobber, but I have never had a tree die while under this type of training (thats probably put a mocker on it now!), but having said that, I have only ever done figs and a couple of Hibiscus. not sure how you others will get on with other types of trees, but my guess is as long as the tree is a gross feeder all should be well.
Sime76 wrote:Would this method work with Elms?
As above, I have not tried an Elm, but from my experience the Elms do not appreciate the totally open mix used with this method and to use a heavier medium risks toxisity from the amount of fertiliser involved. I guess nothing ventured nothing gained tho. Just dont try it with your best tree.

Same goes for you Jamie, sorry, not a lot of help here.

Now your talking, who wants to wait years for a tree to get a good grip on a rock? This works well for RoR style Bonsai. Get a lid with your styrene box, tape box and lid together, cut out the end of the box and plant tree in upright box. Make sure you support the box so it can't blow over tho'.

Cheers
Mate, your post reminds me of a story I heard about a Bonsai nut in South Africa, who after attending one of Dot's lectures on Potting Medium went home and repotted his entire collection into the mix she recommended. He started a whole new collection a short time later. Dot's system just didn't work for him in his situation so please try
One of your figs first

. As for the Elms, read my answer to Sime76's post above. And as for the Celtis, somewhere in the back of my grey sponge I seem to remember someone in Victoria doing this to one and got good results, so maybe worth a try - not much to loose anyhow

The system will work in any container, as long as there is total drainage. If the container holds any "pooled" water the mix WILL become toxic and the plant will suffer/die. Styrene boxes are out there, become friendly with someone in either the Veg Dept or fresh Seafood Dept (Or both

) of you grocery shop and find out what days they get there fresh produce in. If they know you want them they will probably keep some aside for you.
Thanks for the words B/Bruce. I think you might find the Fertilizer presentation was at Coffs Harbour mate, don't think I have ever done anything at Brisbane -
Yet
. Your advice is spot on as well and all you "fastgrowers" out there would do well to head the advice, especially 1. and 3., Bruce isn't kidding. One other thing to remember, with a fig under this type of cultivation there is
NO dormancy, although they do slow down just a small tad sometimes.
Just to clear up the origins of this system as well guys, the technique was told to me by a South Australian Bonsai enthusiast, who was told of it by a Victorian Bonsai grower. It isn't mine, but I know it works because I have seen it and done it myself. Good Luck and happy growing....................
