    I am wondering if anyone here is blooming (or growing, but not blooming, or has killed) Cym. tigrinum with winter night temperatures above 55F or 60F (13 to 15.5C). I've always had it 50F (10C) or below in the winter and am interested in finding out if it can be grown warmer. Thanks.

    Can't help you. Mine grows at 50F or lower night temps and doesn't bloom.

    I grow mine with 13-14'C night temp, no bloom yet, although it had bloomed previously on smaller bulb (not by me). I'm going going to give very dry winter, and see how it goes this winter.

    Thanks for the information, wonderlen. I have found that if you give it a very dry winter you may get blooms, but not a good blooming. If you water all winter the spikes that do form damp off very early (about 1-2 cm long). I cut way back, but no longer completely dry all winter.

    Mine has gorgeous foliage, but hasn't bloomed yet. It is a young plant - 2 1/2 year only, did make a spike last year which failed on me. I have it in my greenhouse where the low temp is 58. I may need to move it out with the other cymbidiums, based on what you all are noting. It is a great looking plant, but of course, the flowers are the ultimate goal!

    Happy growing everyone - Don in CA

    I had this cym years ago and grew it outside under shade cloth nearly all year round. Temps from as low 2c - 3c mostly 8c+. If in flower I took it in under cover. Used to flower every year for me. One thing I did find is that it liked to be pot bound with roots and potted a little higher in the pot than other cyms, like Cym. devonianum & hybrids.

    Yes, I have noted that they like to be potted that way as well - with larger bark for more air space around the roots as well.

    Mine has been growing well (I think I've had it for a year and a half, maybe two years) but I haven't bloomed it. I imagine my temps are too warm (55-60 nights), but even that low some of my phals (esp. violacea & bellina) start to get po'ed, so I don't want to drop it lower. I've debated sticking it outside in the early fall so it can enjoy the cool night temps, just so long as there are no "surprise" frosts.

    did any body try putting cym. tigrinum into a fridge at night and taking it out during the day?? The plant is very small so, i'm sure it will fit no problem. Most fridge temp is around 4-5'C i think, so not sure it will be too cold for it or not.

    In the late 70's I tried putting some hybrid Cyms in the fridge at night. But I now know they probably weren't getting enough light to bloom in the west windows of my loft apt in Philadelphia. So a diurnal change in temp wasn't enough to bloom them.

    I'm not so sure that it needs the cold as much as it needs a drier period.

    I see. Maybe it needs drier rest period. All the blooming plant i seen on the net has always very shiveled psuedobulbs. Maybe they been given a very dry rest.

    Hey, Marni, thanks for the great article in Orchids Magazine! For that matter, I always enjoy your articles! Everyone, keep a look out for your AOS magazine for December, if you haven't already seen it - Marn's article this time is on Cym tigrinum. Again, thanks Marni.

    Thanks, Don, I haven't seen the issue yet. Since I don't grow warm, I frequently ask the range of a plant so I can recommend it to people with different conditions.
