A better picture would give us a better story to read into your problem. We need to see the pseudobulbs.

Yes, a picture of the whole plant will help. Photos on the net of this orchid in bloom are taken in November.

Generally the easiest "Cattleyas" to grow are those that bloom late summer/early autumn. Those that bloom in late autumn/winter are a bit more difficult.

What are your growing conditions like inside?

It's too late to get a picture of the pseudobulbs until next sept. From September on it gets continually dryer in the house as winter gets colder. I keep both orchids watered, I think adequately, all winter. Should I spray them, or at least the Hawaiian wizard, daily?

Just a bit more info. Apart from the winter flowering types there are those that flower in spring, they "rest" during winter.
Down the backyard i have hundreds of Cattleyas, some are in bud and will flower in the next few months, others have formed a sheath and will do nothing for months....in nature, the ancestors were waiting for some event.
As for misting and stuff, it might do more harm than good.These orchids have pseudobulbs to get them through dryer periods.
Over to Tolumniamatt. he will be able to give better information. At least there is a real winter in zone 6a. Though it is interesting to note that the largest Cattleya nursery in Australia actually has light frosts at times during winter but the days are mostly sunny and the temperature lifts.
Do you have any idea of indoor winter temps and humidity readings?

I just figured out what the pseudobubs are on the cattleya. Here's a picture. Today the temp is 66 and humidity 44. I would say though that in october when they come into the house the temp and humidity a a little higher.

Plant looks healthy. The new growth looks small and the leaf dark green. A wild guess would be to increase the light and when you bring them in, put them under lights or a very sunny window to let it finish blooming.

Humidity never bothered mine but enough light would.

Thanks Jane, I'll try more light this fall.

With a bit of effort, I gave this orchid more sun and/or grow light and it's about to bloom. All it needed was more light, thanks.
