How Do I Bring My Mandevilla Indoors Over Winter?
If you wish to bring it in to grow as a houseplant in winter, start by cutting the plant back a bit. This will decrease the leaf loss you see inside and help prime some new growth that's better adapted to indoor conditions. Many people give their plant a preventative treatment to help keep pests from coming inside. Popular sprays that are okay to use on a plant you're bringing indoors include insecticidal soap and neem oil.

How Do I Care for My Mandevilla Over Winter?
Because mandevilla likes full sun outdoors in the summer, it's going to do best in a high-light spot inside. If you have a large sunny window or patio door, placing your mandevilla nearby can be a good spot. Or, keep your mandevilla happy by growing it under a shop light or plant light. (By the way: You don't need a fancy or expensive plant light; a regular old shop light works just fine!) The more light you can give your plant, the better it will do.
Water your mandevilla indoors over winter when the top inch or two of the potting mix dries to the touch. You'll probably find your plant needs a lot less water indoors over winter than it did outdoors in summer because in lower lighting, the plants grow more slowly and, as a result, take up less water. You also don't have the hot sun beating down on the soil or potting mix, so there's less moisture lost to evaporation. Back when I lived in Iowa and moved my Tropic Escape

Will My Plant Bloom Indoors Over Winter?
It depends on the amount of light you have. But, because you mandevilla wants to take a bit of a rest during the winter months, don't expect to see many -- if any -- flowers until you bring it back outdoors in the spring.
