How often does giant rainbow plant need pruning?
Annually, at onset of summer dormancy. Byblis gigantea is a tuberous perennial that dies back to its tuber during summer dormancy — this die-back is natural, not a pruning cue. Remove dead aerial growth at the base after dormancy sets in. Once new growth re-emerges in autumn, do not cut back healthy stems. No active pruning is required during the growing season.
