Of course, I am far, far away from Connie but I think the same principles apply. Watch the weather report, know when the first frost is "normally" expected. Get the GH cleaned out before that. Do your spraying ASAP. Here, in the Gulf Coast near Houston, I put my plants inside around November usually. Again that will vary according to the weather report but I really pay attention to it the later it gets. Last winter the temp in the GH got down to 32 several times and it did not affect the Phals. It was just so cold the heater could not keep the temp any higher.
What normally happens here is that the day before it is going to get cold enough to get the plants into the GH it will rain, a lot. Boy does that make for fun especially with my enormous Platicerum bifurcatum. Poor DH has to manhandle that one.
So, right now, although the day is still a couple of months off, I am making plans as to how to fit in all those plants I have bought this summer. It is going to be tight but I am also going to find new homes for my Hoyas and duplicate rhipsalis and epis. A must do project for this winter will be to repot quite a few orchids.
We had a really nice day today. Cooler than the upper 90s we have had all summer, fall is on the way. Yippeee
