how do you force a christmas cactus to bloom

Well, if you want your Christmas cactus to bloom, you'll need to create a warm, humid environment. Keep the soil consistently moist and place the plant in an area with bright, indirect sunlight. To help it bloom, try giving it a weekly dose of liquid fertilizer. Also, keep in mind that Christmas cacti prefer cooler temperatures at night, so keep the room temperature between 60-65 degrees Fahrenheit. Finally, you can try placing the plant in a location with some gentle air circulation, such as near a fan or open window.
