This front view of the tree shows the root ball after completion of the root washing. When this process is undertaken for the first time it may be prudent not to try and wash all the old compost out right back to the trunk line. The process can be carried out over several re-pottings so eventually all the old compost together with any dead roots can be removed in favour of new fibrous roots.
A light pruning of the roots has also been carried out.

The pot has been prepared with plastic mesh wired into the drainage holes and 2mm diameter aluminium tie in wires set through the wire holes in the base of the pot.

The next layer to go into the pot is the actual compost mix comprising of: -
1 part Kiryu
1 part horticultural grit
3 parts medium sieved Akadama

The tree has been placed in the pot and settled down onto the humped compost.
There were several unsightly roots that crossed each other previously, these have now been relocated and pinned down with aluminium wire.
