You'd think I'd know this by now, but I took a couple of years hiatus from orchids after only being involved with them for short period. Anyway, my question is, how are spikes produced on different orchids? For instance, when a new Dend. cane has finished hardening and is fully grown, but no spike emerges...is that is for it, then? Or do the canes remain barren until it just feels like sending a spike up all of a sudden? And as for Catts, kind of the same question. When a new leave unfolds, hardens and there is no sheath - is that it? Or are sheaths produced later on whenever it decides to do so?
