I usually bring mine in by mid October. Just watch for a frost warning and get them covered if you can. A lot of tropicals can take some pretty cool weather. I don't know where you are located but the mountain areas and further west get cooler much sooner than the Southeast. I'm in Philly near Bucks County so it stays warmer a tad bit longer. I try to stretch the summer as long as I can!!

Yep - all my orchids are still growing happily outside. I will bring them in if it is going below 45 at night, but otherwise they stay out.

I myself find it never hurts to acclimate my tropicals to thier indoor environment a little early. I plan to bring mine in next week. I'd do it now but the rains have brought some nice warm air in. My pams and palmettos seem to hold 50% more fronds through winter if I bring them in before the end of september.

Well it looks like it is going to get cold this weekend. I would like to store my caladiums for next year. I do not have space indoors to keep them in pots. When do I dig them up? do I cut off the leaves, and stems? How do I store them. Also can water hyacinth be kept indoors in a terrarium or fish bowl for the winter.
