How to save Christmas cactus from falling buds

1. Related reasons

(1) Too little light: If there is insufficient light, photosynthesis cannot be guaranteed. There is no way to avoid the phenomenon of flower buds falling.

(2) Improper watering: During the flowering period, the plant will be very sensitive to water. If you water too frequently or if there is too much water, the flower buds may fall off. In addition, if the water temperature is very low, it may also cause the flower buds to fall off. Furthermore, if water is spilled on the flower buds, the same consequences may occur.

(3) Insufficient fertilizer: mainly insufficient fertilizer containing P and K. If nutrients are not supplied, the flowers are likely to fall off.

(4) The temperature is too low: It likes warmth, especially when it is blooming. If the temperature is below five degrees, it will be common for flower buds to wither and fall off.

2. Remedial measures

(1) Control water and stop fertilizing: The most important measure is not to water too much at one time. Especially when the soil in the pot is very dry, do not water it thoroughly at once, but water it slowly and step by step. You can also spray some mist every day, but you need to use water at room temperature. As for fertilizer, some thin fertilizer can be used before the flower buds form. However, after the flower buds form, there is no need to fertilize.

(2) Keep warm and increase light: During the flowering period, it is best to keep the temperature between 14 and 20 degrees, not too high or too low. As for lighting, it is best to place it in a location such as a balcony where there is plenty of light. And, in order to receive light evenly, you can rotate it at regular intervals. If there is not enough light during the flowering period, you can use fluorescent lamps to remedy the situation. Three to four hours of exposure at night will help maintain the flower buds.

(3) Ventilation and insect prevention: Regular ventilation can effectively prevent some insect pests. It is best to open the windows for ventilation at noon when the weather is good. In addition, if pests are found, they can be captured manually if the number is small, or sprayed with pesticides if the number is large.
