What are the solutions for yellowing leaves on a night-blooming cereus?

During cultivation, the night-blooming cereus (Epiphyllum oxypetalum) can develop yellow leaves for various reasons, which is very harmful to its growth and development. So how should yellowing leaves on a night-blooming cereus be handled? Let's learn together with the editor.

1. Shading

The night-blooming cereus does not have high light requirements. If it is placed in direct sun exposure during the growing season, it can easily affect its normal metabolism, and its leaf edges will gradually turn scorched yellow. At this point, we should promptly cut off the yellow leaves, move it to a ventilated, semi-shaded spot, and afterward pay attention to light intensity during the growing season, providing appropriate shade when the light is strong.

2. Increase water

The night-blooming cereus prefers to grow in a humid environment and is not tolerant of drought. If it is lacking water for a long time during the growing season, it will affect the plant's growth balance, and the leaves will gradually wither and turn yellow. So water it thoroughly once in time, then loosen the soil, strengthen ventilation, and keep the soil well aerated. After that, water to keep the potting soil moist, but do not allow waterlogging. Its leaves will then slowly recover.

3. Increase temperature

The night-blooming cereus is relatively sensitive to changes in the surrounding temperature. If the temperature is very low, the plant will grow poorly, and the leaves will also turn yellow and wither due to insufficient nutrients. At this point, artificial heating is needed. When the ambient temperature drops below 8°C, move it into a greenhouse in time and give it full sun to avoid damage from heavy water and freezing.

4. Reduce fertilizing

The night-blooming cereus is a fertilizer-loving plant, but it is not tolerant of heavy fertilizer or raw fertilizer. If too much fertilizer is applied during daily care, or the concentration is too high, the leaves will turn yellow and wilt. So at this point stop fertilizing, apply an appropriate amount of superphosphate solution, then loosen the soil. After that, fertilize mainly with light fertilizer, then water with clear water.

5. Pest and disease prevention

Under high temperature and high humidity, the night-blooming cereus is highly susceptible to scale insects, aphids, leaf blight, and other problems, most of which are caused by poor ventilation. After the disease develops, spots appear on the leaves, ultimately causing the leaves to turn yellow and wither. In the early stage of the disease, you can cut off the diseased leaves, strengthen indoor ventilation, and then spray a diluted omethoate solution for control.
