cordylines grow everywhere down here....and I mean everywhere and thrive.
I grow a couple of varieties including Albertii. This grows in the poorest, driest soil. It is over 20 years old and been cut down several times. heavy soil would be fatal over winter Helena so dig it up.
I think you should forget about growing it in your garden.....incorporating compost would not help. It is an ideal pot plant....if you repot in spring into a larger container it will be larger. I suggest a basic john innes with plenty of grit or perlite.
