Canes too young to go dormant?

[turock]

This is my first year to own dendrobiums, and I have not yet gone through the dormancy/winter rest process.

Here is a picture of my Frosty Dawn, which I purchased in April. When I bought it, it had no roots at all. Since then it has sprouted a ton of roots, two keikis, and two new canes from the base of the plants. As I understand it, the time for winter rest is fast approaching, but I'm worried about overwintering these new growths.

First of all, is this even a species that needs winter rest? If so, should I still avoid the rest for this plant so that its new growths can mature a little further?

I have the exact question on my frosty dawn it has two new canes and they have not fully developed.

I have read that formosae don't need a typical rest like nobiles do, just cut fertilizer and reduce water when not in active growth. When I talked to Roy at H&R, he said he grows his year round and the canes stay leafed for a couple years after maturity. I follow his advice and will treat it normally until the growths are finished, or temps drop in ~October/Nov. Whichever comes first!

I so very appreciate this information, thank you so much. I adore this orchid ❤️

Gotcha. Thanks a bunch! I didn't even know that Frosty Dawn was a formosae.

I have a couple of other dendrobiums, namely a Nestor 'NN', and an aphyllum. Are these in a category that needs a dormancy period?

They should. They're considered "pendant" type Dendrobiums and they require the drier, defined winter rest.
