What Causes the Yellowing of海棠 Flower Leaves
The yellowing of海棠 flower leaves is caused by improper watering, unsuitable lighting, inappropriate temperature, and incorrect fertilization. If too much water is given to the海棠, stop watering and promptly drain the accumulated water in the pot. During the growing period, place it in a place with sufficient sunlight, avoid direct sunlight, and keep the temperature between 18-25 degrees. If excessive fertilization occurs, water promptly or change the soil.
Reasons for the Yellowing of海棠 Flower Leaves
1. Improper watering: If too much water is poured on the海棠, it can lead to root rot, which causes the leaves to turn yellow. During the growth of the海棠, it needs sufficient water, but excessive watering that causes积水 in the pot will result in the plant's roots rotting.
2. Unsuitable lighting: Lack of sufficient light or exposure to strong sunlight can cause the leaves to turn yellow.海棠 enjoys sunlight, and keeping it in a dark place for a long time will cause its leaves to wilt and turn yellow, while exposure to strong sunlight can burn the leaves and cause them to turn yellow.
3. Inappropriate temperature:海棠 requires a suitable temperature for growth, with an optimal range of 18 to 25 degrees. High or low temperatures can lead to poor growth and yellowing of the leaves.
4. Incorrect fertilization: Excessive fertilizer, high fertilizer concentration, or insufficient fertilization can cause the leaves to turn yellow. Too much fertilizer can burn the roots, while insufficient fertilization hinders growth, both leading to yellowing leaves.
Methods to Treat Yellowing Leaves of海棠 Flowers
1. Proper watering: If too much water is given to the海棠, stop watering and promptly drain the accumulated water in the pot. You can also place the plant in a well-ventilated area to evaporate excess moisture. In severe cases, change the soil for the海棠.
2. Provide lighting: If there is insufficient lighting, move the海棠 to a place with good lighting conditions for maintenance, gradually increasing the light. If the plant is sunburned, move it to a shaded, well-ventilated area, and after it recovers, provide normal lighting, taking care to遮蔽 the plant when the light is too strong.
3. Suitable temperature: If high temperatures harm the海棠, promptly cool it down by moving it to a shaded, well-ventilated area. You can spray water on the leaves and around the plant to cool it down. If the temperature is too low, move it to a warm room for maintenance and provide insulation.
4. Proper fertilization: If the plant receives too much fertilizer, water it to dilute the excess fertilizer. In severe cases, change the soil. If there is insufficient fertilization, provide additional fertilization, applying thin layers of fertilizer frequently.

H海棠 flowers are best planted in well-drained, slightly acidic soil, with the most suitable growth temperature between 18-25 degrees. They also need to be placed in a sunny location, avoiding direct sunlight. Pruning should be done during the leaf-falling period and the growing period.
