When do you bring orchids indoors?

[Judi]

I watch the weather starting Labor Day. All my chids are in a screen porch by the house so there is a warmer micro-climate for them. Once night temperatures are regularly in the mid 50's they come in except for the Zygos and Cymbidiums which stay outside until temperatures are routinely between the high 40's to around 50. They spend the winter in a spare bedroom that is sunny but temps are around 50. Last couple of years the majority came in around the end of Sept. and the Zygos and Cyms in early Oct. But every year is different.
