All the materials needed for re-potting and wiring:
I decided to attach the wire to the bottom of the pot for extra stability, and added some standard slow release fertiliser.
Self-Confessed Noob Mistake #1: (I'm sure there will be several more in future.) I used the wrong type of wire. I just grabbed the first wire I saw at Bunnings which happens to be fencing wire. Aside from being a garish silver colour, it's very stiff and difficult to bend. My hands were sore by the time I was only half-way up! I'll get some proper bonsai wire to use next time, I promise!
I think one of my next priorities might be a nice stand to keep the plants on!
