Phormium in a pot

Hi, I have 2 Phormiums growing in large pots, one is 'yellow wave' and the other 'bronze baby'. They are now quite large and my question is can I keep them in the pots or do I have to split them? If they can be split is there a special way of doing it?
Thanks, Michael

If they're happy, you can keep them as is. If they are struggling as a result of being overcrowded, divide them using a sharp spade or large knife in spring, when they will be full of the joys of spring (i.e.growth hormones) and will recover from the shock as long as you don't cut the pieces too small. Plant the pieces in good new compost with slow release fertiliser mixed in and don't overwater. Good luck and have fun.

Thank you very much Alexia. They look quite happy at the moment but I'll wait for spring and then divide them into two to give them a bit of a boost!
