I wish we had some Dendrobium experts here! I had read about that winter dry dormancy with some of them, but a NOID one went dormant last winter and, since didn't know what type it was, I started watering when the new growth got about two inches high. OOPs! The new growth immediatly rotted. I haven't trashed it yet, as the old canes still look ok. I've left it pretty much dry all summer. Don't know if it will recover or not.
Everything else is in anticipation mode...lots of new growth and some spikes and buds on an Onc., but nothing new blooming, except the one I refer to as "the weed". I'll post that if I got a decent pic.
