Moving A Cordyline.
Moving a Cordyline in an ideal world before moving a big plant the autumn before you should dig a trench around the plant and back fill with good compost and then in the following summer you dig up the plant,taking as large as root ball as possible.If you have not got time to do this take as large as root ball as you can,replant it and ensure that it remains watered during any dry periods for at least the first year.However being such a large specimen it may not survive as the shock may be too great or it may be difficult to get a large enough rootball with it.
