Can I dig up and move a Cordyline?
This will depend on the size of the plant, and how much soil (root-ball) you are able to lift with it. C. australis (the common green type) are quite resilient and able to cope with being moved up to around 2m (perhaps 4 years old?), provided as much as possible of the long central tap root is taken out with it and it is given plenty of water for 6 months after moving. It is best to do this in April/May, once it has started growing again after the winter. It is possible to move larger plants but this is best done by professionals with suitable root-balling equipment and cranes.
