Most Mandavilla are climbers and vine up trellises so that makes it very difficult to bring them inside. Mine constantly blooms, it's about a year old, takes lots of water and i try and separate the vines that twist too tight so it doesn't "choke". Mandavillas, like Hibiscus take alot of TLC and hands-on care. Touch the leaves, break off the dead blooms and leaves. Makes a big difference versus commercial bloomers that you would normally add to the dirt. It's in partial sun under a front porch and has been beautiful. For the winter months, since there's no way to bring it inside I wrap it as best I can during a frost.
