Over wintering Plumerias
I know its early to think about winter. I have started working on my plans to bring in my plants for the winter over the next 3 week, how low of a temp can plumerias take ? I have a cold room in my basement that I store lots of plants and bulbs for the winter it gets down to around 65f, would it be ok to keep my plumerias there? should I strip off the leaves before I store them or let them drop off,I have a area that I keep other plants in that stays about 70/75 and there under light.I have one that I know will stay green all year so that will go in a south window but the rest I'm not sure what to do? last year the ones I did keep under lights didn't drop there leaves until late Feb.
Thanks for any help you can give me
