can christmas cactus grow outside

Christmas cactus is a houseplant, so it doesn't do well outdoors in colder temperatures. They're adapted to growing in the warmth of homes or greenhouses, and they can't survive in freezing temperatures or frost. They also need plenty of bright light and humidity to grow and bloom properly, so they're best kept indoors. If you want to keep your Christmas cactus outside, you'll need to bring it inside before it gets too cold. It's best to keep your Christmas cactus inside where it can thrive in its preferred environment.
