Most people will start wiring trees using aluminium wire, however some species are better wired using annealed copper wire. Junipers are always best wired with copper, the reason for this is that the copper wire is much stronger, is able to hold a branch in shape with a much thinner strand than aluminium and it also maintains its shape better and is less likely to be bent by birds, or while moving your trees around. below is an example of how juniper can be wired with aluminium, note that we always try to avoid crossing wires and aim for a neat appearance on the tree.
I will be posting images of wiring using copper soon.
