I brought mine in at the end of September and it's dropping leaves like crazy.

How that? I put my one at a south-facing window, where it gets full sun
from about 11 a.m. till 5 p.m. It's blooming like crazy.

I pruned it (I cut away about half of the plant...) and brought it in in
September. I'm in zone 6b (Munich, Germany), but we already had quite
cold nights lately.

I'd recommend to overwinter it at about 15-18 degrees* (can also be
more), with as much light as possible (check for spider mites!). Water
when it looks thursty
I already tried to overwinter a Bougainvillea at 10-15 degrees*, but I
killed it this way...
Bring it out again when night temperatures don't drop below about 10
degrees*. They are very sensitive in our climates..

*Celsius, of course....

Bye, Gaby
