They can be done now, but it is better to split in Spring, as Songthrush said, when the new shoots are beginning to poke above the soil.

I split mine in March Parfour. They have always done very well-so far. They are in pots so I split them every three or 4 yours or when they are really pot-bound. Good luck.
