I am not sure if pruning is the right word but I have a BIG Cordyline (C.
australis?? cabbage palm). I do not want to kill it but it is humungous
with one big "trunk". If I cut it in half (half way up the trunk; not left
half vs right half ho ho ho), will it regrow? Being monocots, they grow
funny so I would not be surprised if teh answer was that this would kill it.
Nonetheless, in big old Irish estates (Fota and Mountstewart) you do see
ancient ones with lot and lots of smaller trunks, rather then one big one so
that suggests they can be persuaded to spread out. Maybe that has to be
done from an earlier age.
