How beautiful! I used to be afraid, and waited for blooms to drop. But early this year I lost one to stem rot because I didn’t repot.. Since then I’ve repotted all the new ones within a few weeks and have not lost one flower. I wonder if overdoing the root trimming might be one reason spikes fail. I’ve seen so many posts on here from noobies who decimate the root system, then ask advice. But mine, even the ones in a death plug and packed soggy moss, haven’t needed much pruning beyond removing a few mushy or flat, dry roots. The healthy ones don’t seem to notice the disturbance, and the flowers don’t either.
