What Causes the Camellia Yellow Leaves to Fall Off
Camellia yellow leaves and falling off are caused by excessive watering, unsuitable soil, lack of nutrients, and normal metabolism. Camellias are suitable for planting in loose, fertile, well-drained, and humus-rich acidic soil. They should be placed in semi-shaded areas, avoiding strong sunlight in summer. Watering should be frequent but not excessive, keeping the soil moist without积水. Apply decomposed soybean cake water once a month.
Reasons for Camellia Yellow Leaves
1. Excessive Watering
Camellias like a moist environment, but excessive watering can cause soil积水, leading to root rot and resulting in yellow leaves.
2. Unsuitable Soil
Camellias thrive in acidic soil. If the soil is alkaline or the nutrients are gradually depleted, it can lack nutrients and cause the leaves to turn yellow.
3. Lack of Growth Elements
During normal growth, camellias require certain growth elements. If there is a lack of nitrogen, yellow leaves and falling off may occur.
4. Normal Metabolic Phenomenon
Camellias are evergreen plants, and their leaves usually do not fall off quickly. However, they may undergo leaf replacement, causing the leaves to turn yellow, which is a normal phenomenon.
What to Do When Camellia Leaves Fall Off
Method 1: If yellow leaves and falling off are caused by excessive watering, stop watering first, then loosen the soil and place it in a well-ventilated, shaded area for a period of time. Once it recovers, water moderately.
Method 2: If yellow leaves and falling off are caused by unsuitable soil, change to a soil that is slightly acidic and rich in humus regularly. Before replacing the soil, place the new soil in the sun for a few days to prevent the occurrence of diseases and pests.
Method 3: If yellow leaves and falling off are due to normal metabolism, no special treatment is needed, just maintain normal care. If it's due to a lack of nutrients, supplement the required nitrogen, which can be done by applying decomposed soybean cake water or adding a 1% ferrous sulfate solution once a month.
Preventing Camellia Yellow Leaves and Falling Off
Camellias are suitable for planting in loose, fertile, and well-drained soil. They should be placed in semi-shaded areas, avoiding strong sunlight in summer. In autumn and winter, provide long hours of sunlight to promote bud differentiation. Watering should be frequent but not excessive, keeping the soil moist without积水.
