Answer: This is not so unusual for bougainvillea, it tends to sulk when brought inside in part due to the lack of light and shorter days. It could also be due to overwatering. As the plant slows its growth, it needs less water as well. This is a cyclical bloomer, so if you need to trim it back at all, do that now. Then store it for the winter in a cool but bright room. (A temperature of 55 F would be fine.) Do not fertilize it this winter. In the spring, when it naturally starts to try to grow again, give it as much light as you can and begin to fertilize and water a bit more. When days are over 55 degrees, set it outside so it can have more direct sun (shelter it on cold nights). Good luck with your new plant!
