If you want to make sure your Christmas cactus plant stays healthy and blooming, there are a few things you need to keep in mind. First, you should water your plant regularly, making sure to keep the soil slightly moist. You should also make sure to place it in a bright, sunny spot so it gets plenty of light. You should also fertilize the plant periodically with a liquid fertilizer to keep it healthy and thriving. Finally, make sure to protect it from cold temperatures and direct sunlight, as these can cause the plant to die.
