Dendrobium Kingianum doubt

[Orquiadicto]

Last summer I bought two Dendrobiums Kingianum without flowers. They have both bloomed because part of the old spikes are still there.
One of them had several keikis and has grown tons of them since.
The other one has only grown one keiki, but now it is growing what I think might be flower spikes. I've got them outside (actual hights about 60-65 F, lows about 40-45 F). My question is what I should do now. If it really bloomspikes, should I leave it outside or would it be better to bing it in? The "spikes" are too small to see on a picture.When they are bigger, I'll post a picture.
Another question is whether they only bloom on new canes, or do they also bloom on old canes that have already bloomed before?

I usually take the flowering plants indoors especially if they open the blooms; it extends their blooming life...some dendrobiums flower on old canes thats why I never discard them...

I leave mine outside (tho do have a recently removed and potted keiki inside, and the move didn't seem to affect the spikes, but I do keep my home on the cool side) - both last year and this, started spikes early fall, last year bloomed early spring. Yes, they can bloom on older previously bloomed canes.
These can take short periods of temps around freezing. I do protect from frost (just to be safe, don't want to lose the spikes) by having it on a sheltered porch - when buds started to develop, I put it in the garage on nights that might be freezing (again, just to be safe)

Thanks for your replies. I'll leave them outside. If there are blooms perhaps I'll take them in just to enjoy the blooms.

Each of my two Kingianums is blooming with two spikes each. I bought them without flowers, so I had no idea what the blooms would look like. I've read somewhere that they are fragrant, but mine aren't. Is that normal?

I've bloomed two of these (sold one and killed the other); one was mildly fragrant and the other didn't seem fragrant at all. Line-breeding of the species for flower color and size may have affected this in cultivation, as fragrance is often ignored by (or at best a secondary consideration of) breeders when making crosses.

Mine only has a fragrance when the sun is on it warming up the flowers. It fills the room with the sweet smell, but otherwise you have to get your nose in the flower to smell it.

If you should bring yours in to enjoy the flowers, they may last a bit longer since they are not exposed to the elements. Things like wind, rain, etc... can cause the blooms to pollinate and drop off, from my understanding. It was sugested to me a while back that if something is in bloom and you want the blooms to last longer and enjoy them, then bring it inside so you can control the environment and not risk loosing them prematurely.

Those temps should be fine to leave outside, I would think that the flowers would be ok and perhaps its warmer inside your home especially at night.

If you take the plant inside I would do so in order to avoid bugs affecting the flowers. I would imagine you live in a good climate to grow these.
