Which orchids in YOUR collection get a winter rest?

[gnathaniel]

Hi denvervet, Dendrobium Spring Doll is a hybrid involving species like moniliforme and nobile, so it is in the group generally said to need a rest. I've found this type of hybrid to be very tolerant and easy to bloom without an extreme seasonal variation, some of them will start pushing buds after just a few weeks of nights below 60 F. Should be easy to grow if kept warm and wet while actively growing with a cool and drier (not bone-dry) period of 1-3 months after growths mature. Hope this helps!

Thanks a lot Nat. I had it where it was getting morning sun but recently moved it to very bright light under a skylight, I don't think it liked the hot summer sun it was getting. The leaves seem to be very light green, but its got flower spikes!

dendrobium aggregatum aka lendeyi var majus and my dendrobium aggregatum var jikinsii and also dendrobium kingianum. most spiecies dendrobium by what i here require a winter rest. i would like if some one could post there method for winter rest as there is much controversy on what "rest" means. do you with hold all water or just sum or do u just with hold fertilizer

No fertilizer. When you begin to see quite a bit of shriveling, mist or water lightly. Never soak heavily. When vegetative growth become inactive, your plant will get through the winter with very infrequent watering. If, for example, you water once per week in the warmer months, you may be able to cut back to a light watering or misting once every three weeks. Once a plant is dormant and given lower temps, even with a lot of watering, it will not wake until spring and at that time you can resume regular culture. Your winter rest is over.

	Mistking Looking for a misting system? Look no further. Automated misting systems from MistKing are used by multitude of plant enthusiasts and are perfect for Orchids. Systems feature run dry pumps, ZipDrip valve, adjustable black nozzles, per second control! Automatically mist one growing shelf or a greenhouse full of Orchids. See MistKing testimonials

Everything I have, other than Vandaceous and phals.
Anything with a bulb gets what nature throws at it.

HI folks, I did not see my Den. on the list but I am still wondering if I should rest it. I have a Den. Spring Doll 'Sweetheart' HCC/ADS can like den. Can anyone help me?

[denvervet]

For some reason my post didn't take, I will post it again. Its probably my terrible computer! I am still not sure if Den Spring Doll 'Sweetheart" HCC/ADS needs a winter rest....My Den. Aggregatum var. majus 'Fields' grew extremely well this year and I have been resting it since halloween. Its pseudobulbs are already shriveling, I live in Denver and its very dry here so I watered it just a little today, should I? You guys are great in answering questions, thank you so much!

Your plant appears to have at least one parent that is a nobile type so I would stop fertilizer and reduce water until buds begin to appear then you can gradually increase water but hold fertilizer until flowering is complete.

[denvervet]

Ok, thanks for the advice.

Anything in Central America gets a pretty serious rest.
3 months or so at altitudes above 1500 feet and below 4000 feet.That's the time when they flower.Same with flowering trees.
