I have encouraging news, ladies. In Dr. Motes' Vanda book he says some Vandas will bloom 3 times per year! In fact . . . I'm pretty encouraged by my one little yellow mini-Vanda that has now bloomed twice this summer.
I agree with the mid-50's to bring them indoors, but if you can keep them in a sunny place, and give them lots of water and food as well, there's hope for more flowers than what we've had.
Um, Gigi sometimes we get the first "cool" front in October, I think. But you're right, the first really cold weather - days in the 70's - is usually November at the earliest. It's the night time temperatures you've got to watch for, as far as the orchids are concerned.
