Moving orchids indoor: What to do with those who need a rest

[drosera]

Hello everyone! I hope you can help me with a question I have.
I usually grow my orchids (especially Cattleya) from spring to autumn outside, in the garden. In October-November, when temperatures start to drop (currently the minimum is around 8ºC degrees) I move them into a room with lights, where the temperature is stable between 22-23ºC during the day and 15-18ºC at night. They spend the winter here, because outside frosts are frequent. The question is what do I do with some recently acquired species that need rest (some Dendrobium, Cymbidium, Rossioglossum, Laelia...), because I am afraid that they will reactivate with the increase in temperature and not get the necessary rest.

Thank you very much!

I grow catts, dendrobiums, rossio, laelia, paphs, phrags, etc, etc. Used to grow outside around six months of the year, inside the other six. Now they're inside all the time in a sunroom that's not air conditioned and supplemental heat in winter. In fall/winter months, they are all at just about the same temperature range as you've described.

Some of those plants can spend the winter outdoors. You can bring them inside when there may be frost.

The words we use determine how we think. Those plants don't need rest. They are still metabolizing every day. Some need lower temperatures, some less fertilizer and some less water. Some need a combination of all those. Using the word 'rest' can cause us to overgeneralize.

Thanks for the answers! In my area, frost can occur daily for several weeks, so I have to keep them inside for a long time.
My question is mainly about those plants that have a more veritable rest period (less water but also low temperatures), such as Dendrobium nobile type or some Cymbidiums. If the plant is now supporting a minimum of 8-10 ºC (outside), and has been like this for a few weeks, and suddenly I move it inside with a minimum temperature of 15 to 18 ºC, won't there be a problem? Will the cycle start again (generate new shoots) when it really should not grow for a several more weeks, trying to simulate what happens in its natural habitat?

Thanks again!

Nobile type Dendrobiums need 6 consecutive weeks of night temperatures of 12C or lower to flower reliably. Some of the hybrids need less chilling. They still need water during this period, but not fertilizer. Some people have found putting them very close to windows is enough chilling, but there is the risk of freezing. I would leave them outside as long as possible, then try to put them into the coolest area possible. Can you close the heating vent in one room at night and let the temperature drop?

I can't address Cymbidiums, but I know they're difficult to flower in cold-winter climates if they need to go into a house without a cool area with high light.

I appreciate your recommendations! I will try to find a place where I can maintain these temperatures, but I live in a well-insulated house and it is a bit complicated.

Greetings!
