I have three noid dendrobiums that I need advise for. I've included photos to help, I hope. Den#1 I bought about 5 years ago. It was small, but had a dried up bloom spike, so it was blooming size. It has not bloomed since. Last year, I gave it a strict rest period from Halloween to Valentine's day. No bloom, but it grew well over spring and summer. I was getting ready to give it another rest when I spotted it's first spike! Should it still get a rest now or wait till after flowering?
Den#2 I've had for about 4 years. It was bought in bloom and foolishly I did not take a photo. By recollection, the blooms resembled photos I've seen of "antelope type". Like Den#1, it had a rest period last year, and it is growing well, but still no blooms. Do I try another rest?
Den#3 I bought 18 months ago, in bloom, and it has just stopped blooming for the first time. Just before each spike would finish, a new one would emerge. It has never had a rest and I planned to do so now, but a new cane has started to grow! Is it best to keep up the same routine year-round for this one?
All of them are growing with western exposure, indoors, with some filtering from trees growing outside. My Catts are growing and blooming successfully in the same light.
Any advise would be appreciated.
