| Solution | Reduce watering frequency and allow soil to dry out between waterings to prevent root rot. |
Overwatering can cause camellia leaves to turn brown. When a camellia plant receives excessive amounts of water, its roots become waterlogged, leading to poor oxygen supply and root rot. This root rot prevents the roots from absorbing nutrients properly, resulting in a lack of essential nourishment for the plant. As a result, the leaves start turning brown as they are unable to receive the necessary nutrients and water.
To address this issue, it is important to adjust the watering frequency and amount for camellia plants. The first step is to ensure that the plant is placed in well-draining soil, as this helps prevent waterlogging. Additionally, it is recommended to water camellias deeply but infrequently, allowing the soil to dry out slightly between waterings. This helps promote healthy root growth and prevents overwatering. Regularly checking the moisture level of the soil by sticking a finger into the soil can also be helpful in determining when to water. Adjusting the watering schedule according to the specific needs of the camellia plant and providing proper drainage will help prevent the leaves from turning brown due to overwatering.
3. Underwatering

|---|---|
| Solution | Increase watering frequency to ensure soil moisture is consistently maintained, preventing dehydration and browning. |
Underwatering is a common reason for camellia leaves turning brown. When a camellia plant does not receive enough water, it struggles to absorb nutrients from the soil, causing its leaves to dry out and turn brown. Inadequate water supply can also lead to stress on the plant, making it more susceptible to pests and diseases.
To address this issue, it is crucial to ensure that the camellia plant receives an adequate amount of water. Regular watering is essential, especially during dry periods or when the plant is actively growing. It is important to water deeply, allowing the water to penetrate the root zone of the plant. However, it is equally important to avoid overwatering, as this can lead to root rot and other issues. Checking the moisture level of the soil regularly and adjusting the watering schedule accordingly can help maintain optimal hydration for the camellia plant.
Additionally, providing a layer of organic mulch around the base of the plant can help retain moisture in the soil and prevent evaporation. Mulching also helps regulate soil temperature, reducing stress on the plant. Ensuring proper drainage in the planting area is vital to prevent waterlogged soil, which can also cause browning of the leaves.
By addressing the issue of underwatering and implementing these solutions, camellia plants can regain their health and vitality, with green and vibrant leaves.
4. Nutrient deficiency

|---|---|
| Solution | Increase watering frequency to ensure soil moisture is consistently maintained, preventing dehydration and browning. |
Camellia leaves turning brown can be attributed to nutrient deficiency. When a camellia plant lacks essential nutrients, it directly affects its foliage, leading to browning of the leaves. This problem may occur due to insufficient levels of nutrients like nitrogen, phosphorus, potassium, or iron in the soil.
To address this issue, it is crucial to provide the necessary nutrients to the plant. Conducting a soil test can help identify the specific nutrient deficiencies and allow for targeted fertilization. Adding organic matter, such as compost or well-rotted manure, can improve soil fertility and provide a slow release of nutrients. Additionally, using a balanced fertilizer specifically formulated for camellias can help replenish the lacking nutrients.
Regularly monitoring the plant’s nutrient levels and adjusting the fertilization accordingly will promote healthy green foliage and prevent further browning of the leaves.
5. Fungal or bacterial diseases
