1. Reason: Camellia likes humid environment, but excessive watering can easily cause soil water accumulation, resulting in root waterlogging and rot, resulting in yellow leaves.
2. Treatment method: First, suspend watering, then turn over the soil, and place it in a cool and well-ventilated place for curing for a period of time.After you recover slowly, you can carry out normal watering.It is necessary to keep the soil moist, but not stagnant.
1. Reason: Camellia japonica is suitable for growing in acidic soil. If the soil is alkaline or the nutrients of the soil are gradually lacking, making its nutrients insufficient, it is easy to cause the leaves to turn yellow.
2. Treatment method: Regularly replace the flower soil for it, and pay attention to the nutrients of the soil.It needs to be replaced regularly with acidic and humus-rich soil.Before exchanging for new soil, it is necessary to expose the new soil in the sun for disinfection to prevent the occurrence of pests and diseases.
1. Reason: Camellia japonica is an evergreen plant. Its leaves generally do not fall off in a short period of time, but may change leaves.During the period of leaf change, the leaves will turn yellow, which is normal.
2. Treatment method: If this phenomenon occurs, it is not necessary to take special treatment measures, and normal curing is OK.
1. Reason: Camellia japonica needs some growth elements during normal growth.If nitrogen is deficient, yellow leaves will appear.
2. Treatment method: At this time, it is enough to supplement the required nitrogen element.It can be applied once a month with decomposed soybean cake water or with 1% ferrous sulfate solution.
