Asked the same question about the K. thyrsiflora I bought earlier this year since it's grown so much over the Summer.
The nursery told me to wait until "after St. Valentine Day" to re-pot, using a container at most half an inch larger than the present one to avoid the plant from developing too large of a rootball. Very interesting fact, they told me to avoid cactus and succulent specific compound and to use instead a citrus tree potting compound.
PS: this nursery only uses plastic containers even for the largest and most expensive plants, so I'll stick too that.
