What to Do When a Christmas Cactus Drops Its Leaves? Cause Analysis and Solutions
There must be a reason when a Christmas cactus drops its leaves. Fluctuating temperatures that rise and fall suddenly make it impossible for the plant to adapt to the temperature changes, soil that has become poor and dry-hardened can no longer support the plant's continued growth, overwatering or forgetting to water, and improper fertilizing that causes fertilizer burn can all lead to the Christmas cactus dropping its leaves.
1. Control the temperature
The Christmas cactus likes a warm environment. Temperatures that are too high or too low are both bad for the plant's growth, so the temperature should be kept in a relatively stable state. In summer, when the temperature is too high, spray water mist more often to cool it down and make sure the temperature does not exceed 30 degrees. In winter, move it promptly to a warm indoor spot and keep the temperature no lower than 10 degrees to avoid cold damage.
2. Replace the soil
A potted Christmas cactus needs its soil replaced about every 1 to 2 years. Going a long time without changing the soil causes it to harden and lack nutrients, so it can no longer support the plant's continued growth and the leaves will drop. The soil needs to be replaced with fresh soil on a regular basis and the plant tended anew. When changing the soil, trim away the old, weak, diseased and dead roots as appropriate, and disinfect them.
3. Water properly
Growing a Christmas cactus requires regular watering to provide the moisture the plant needs for growth, but watering must never lead to waterlogged soil, otherwise the roots rot easily and the leaves drop. At this point, stop watering immediately, loosen the soil, and move the plant to a ventilated spot to speed up evaporation of the excess water and restore the soil to normal moisture.
4. Stop fertilizing
Growing a Christmas cactus requires appropriate fertilizer to supply the nutrients needed for growth, but fertilizing should be done with light applications given frequently, avoiding raw or concentrated fertilizer, otherwise the roots burn easily and the leaves drop. Stop fertilizing and flush with clean water to dilute the excess fertilizer, then pay attention to fertilizing sensibly afterward.
