What to do if your Christmas cactus (Schlumbergera) hasn't bloomed in 5 years? After misting and bagging, flower buds burst out all over the pot

The Christmas cactus blooms beautifully, with layer upon layer of petals, like dancers in the air, gorgeous and colorful, and it is deeply loved by flower growers. But some growers have kept a Christmas cactus for five or six years and it just won't bloom, and they don't know why. Let's analyze this problem,
If your Christmas cactus has strong, healthy leaves but simply won't bloom, the main reason should be that the light was not controlled properly
The Christmas cactus is a short-day plant. Around October each year, which is the flower bud differentiation period for the Christmas cactus, it needs to receive 6 to 8 hours of light per day, and be kept away from light the rest of the time. We can cover the Christmas cactus with a black plastic bag or put it in a small dark room, then take it out the next day to receive sunlight. This is the method circulating online known as putting it in the dark room,
At the same time, spray the Christmas cactus with monopotassium phosphate or Huaduoduo every 10 days or so to promote flowering. Spraying two to three times is enough. Monopotassium phosphate can promote flower bud differentiation, increase the number of flowers, and protect the flowers and buds
With this treatment, in about a month the Christmas cactus will sprout many small flower buds, and then you can care for it normally. Put it in a place with fairly abundant sunlight and quietly wait for it to bloom
After the Christmas cactus flowers fade, promptly trim off the spent flowers and pinch off the wilted, soft leaves, then apply a multi-element organic fertilizer or compound fertilizer once to replenish the nutrients consumed by flowering. If you want the Christmas cactus to bloom a second time, you can apply phosphorus and potassium fertilizer again after half a month, combined with short-day treatment. In this way, in about a month it can bloom again, except that the leaves will become rather thin,
If you want to grow the Christmas cactus leaves thick and strong, you can apply a multi-element organic fertilizer and let it rest for a month, and new leaves will grow out, becoming thick, fleshy and glossy
