I received several Catasetinae from a Brazilian vendor at the Redlands show in May. They normally arrive bare root with leaves removed, which makes sense to me thinking they would normally be going at that time anyway. And I then leave them bare root until they start new growth, which has worked very well the three years I've done this. (I'm in the northern hemishpere.) But one of them started spiking, which makes me think I should pot it up. I was thinking maybe I should use something like clay pellets as opposed to something that would hold more moisture. Does anyone have any suggestions?
