The wire was taken off, branches edited. Then it was decided that the whole tree should be elevated in teh pot by 2.5 cm. So I took it out of the pot and repotted it 2.5 cm higher. I did not touch the root ball at all. Some guy wires were aplied and some thick branches had to be wired again. Now the spruce is well on it's way to become THE candelabra spruce. The root spread is 36 cm, compared to a height of 75 cm.
