Which orchids in YOUR collection get a winter rest?

Anyone know?

I did a quick scan here and couldn't find any info. so please don't shoot me if it's here and I overlooked it. Thank You.

Dendorbium loddigessii will bloom with a partial rest or complete rest. They can handle similar conditions to den moniliforme or a complete rest. Den moniliforme, (I forgot to mention my den moniliforme) hercoglossum and goldschmidtianum can stand either a partial rest or very short rest and will bloom either way as far as I know. Dendrobium loddigessii can stand a complete rest with nobiles as well as a partial rest with slightly drier and cooler conditions. The key is getting them drier than normal without drying them to the cane shriveling point. You should try cooling down to 50F which should be enough of a temperature drop to induce blooming.

Thanks for your response, Florida guy. So basically, the same culture as nobiles or, not as drastic, do you know? What's the advantage here to withholding water if they bloom with or without it?

Thank you again.

Camille, did you ever find out about this one? I'm thinking of getting one and would be interested to know too.

....and also, the culture for Dendorbium loddigessii?

I know that it needs less water (what's 'less'?) once the leaves fall off until the spikes appear, but does it need a proper winter rest, with cool temps and almost no water? And I don't know if I have to reduce water after the leaves fall, or if I need to reduce it before to make them fall.

Basically They can stand a more dry rest like nobiles, or a more slight rest like hercoglossum and goldschmidtianum. They seem to bloom regardless of how much water they get or how much you withhold while resting them. The only thing that watering more does achieve is less cane shriveling and them being used to getting more water during that time of year. If you decide to rest it, a more complete rest might also encourage more blooming so keep that in mind. Honestly in my opinion, the best dendrobium species is cucullatum (formerly aphyllum/pierardii). Mine have not had a winter rest yet and are starting to bloom even with abnormally frequent watering during summer. They seem to bloom no matter what conditions they get even without a winter rest but will bloom better if they get a dry cool rest. I also think giving most orchids a cool dry rest or cooler and drier than spring/summer weather will allow them to store more energy for more vigorous growth in the growing season.
