I started this thread at bonsaiTALK around a year ago, but I thought it might be appropriate to continue it here. I had initially called this planting a 'Mallee-style clump', but in the light of recent discussions about Australian styles, I am content merely to call it a clump for the time being.

The first 3 pics show my initial styling efforts, photographed in March 2008.
Next are a couple of pics from August 2008. The planting has been re-strung and re-wired, and apparently allowed to grow out of control.

During the scorching days we've experienced lately, I had noticed that the little Eucs were wilting at the drop of a hat, even with regular dunking. This is often a sign that the roots have grown to occupy every last bit of space in the soil. So, I reckoned that a repot was in order. I recklessly hacked off about half of the foliage load, tipped out the gravel mulch and began the arduous task of working through the the tangled rootball. Much to my horror, I discovered that the proprietary Bonsai mix in which I had planted the seedlings had turned more-or-less into a compressed mud brick over the past 18 months or so. The roots were healthy enough, but a good dose of my new mix should make them even healthier (and easier to untangle in future). I had intended to merely tease out the edges of the rootball and slip-pot the clump, but I got a little carried away and removed about 2/3 of the roots...

Finally, I repotted in my new soil mix and wired the roots in for stability.
Over the coming days/weeks, I expect to refine the planting, especially with regards to the way the two right-hand trunks are oriented. There's still a long way to go, but I like to think I'm on the right track. Comments, abuse and general banter gladly accepted here.
Thanks.
