I'm also a newbie to plumeria, and live on the other side of CT from you. I am working on obtaining my first plant, and hopefully it will do OK in my kitchen, which is probably a lot less than optimal for this plant, but my other tropicals seem to survive here.

If you would like to compare notes as we go, please feel free to contact me at my regular email, per my member page.

Good luck!

Richie,

I would keep your seedling in a sunny window when nights get below 50 degrees. Mist it occasionally as they are prone to spider mites. If leaves begin to yellow and drop you should reduce watering. Some seedlings don't go dormant their first winter. Monitor the soil. If the plant is taking up moisture you can continue to water carefully. If it drops leaves and does not take up water, reduce watering, since it's probably going dormant. The thickened stem will store what it needs to survive until it comes back out of dormancy -- anywhere from Feb to April.

Thanks Dave

I also live in Ct. and am presently overwintering my plumeria in an unheated sun porch. I watered it in the fall and then let it go dormant. I haven't watered it since. It looks good and I have my fingers crossed. I'm wondering when I should start to water it to bring it out of dormancy.
