Reasons why Christmas cactus does not bloom

Christmas cactus is a green ornamental plant that people like to cultivate most, and it can bloom bright and beautiful flowers. However, many people find that it never blooms when they cultivate it. What is going on? What causes Christmas cactus not to bloom? The following editor will analyze it in detail for you.

1. The lighting time is too long

There are many reasons why Christmas cactus does not bloom during cultivation. This plant is a short-day plant and is usually exposed to light for no more than ten hours a day. If the light exposure time is too long, it will affect the bud development and cause it to not bloom.

2. Temperature discomfort

Inappropriate temperature is also the main reason why Christmas cactus does not bloom, especially when the temperature is too low, it is difficult for Christmas cactus to bloom even if it takes in water and nurtures buds. At this time, you can directly move the flowerpot in an environment where the room temperature is above 15 degrees, and then move it indoors for people to appreciate it after it blooms.

3. Large temperature difference between day and night

When growing Christmas cactus, pay attention to the large temperature difference, which is also one of the main reasons why it does not bloom. When the temperature difference between day and night is too large, the flower buds that have been nurtured by the Christmas cactus will be damaged or fall off. Especially in November, when the temperature changes significantly and the temperature difference between day and night is large, be sure to move the Christmas cactus in time, place it in the sun during the day, and move it to a warm room at night.

4. Improper fertilization

Improper fertilization is also the main reason why Christmas cactus does not bloom, especially after Christmas cactus enters the flowering period. If excessive nitrogen fertilizer is applied, it will cause the Christmas cactus to grow larger and reduce the formation of flower buds, causing it to not bloom. The best way to deal with it is to reduce the supply of nitrogen fertilizer and increase the supply of phosphorus fertilizer, so that Christmas cactus can bloom a large number of bright and beautiful flowers.
