Your Christmas cactus is experiencing some issues with blooming this year, which could be due to a variety of factors. One of the most common reasons for this is an insufficient amount of light. Try moving your plant to a sunnier spot or using grow lights if necessary. Another issue could be a lack of water or too much fertilizer. Ensure you're following the proper watering and feeding schedule for your plant, and try changing up the fertilizer if necessary. Additionally, the temperature in your home may be too high or too low for proper growth.
