1. Normal metabolismCause: Normal physiological metabolism may cause signs of aging and yellowing on its bottom leaves. Solution: If the leaves at the bottom turn yellow, this is a normal growth phenomenon and there is no need to worry. At this time, normal fertilizer and water management is sufficient. 2. Improper lightingReason: If the plant is kept in a dark place with insufficient light for a long time during its growth process, it will lose vitality, causing the leaves to turn yellow and fall off. However, if the sunlight is too strong and the plant is exposed to the sun for a long time, its leaves will be burned, turning yellow and falling off. Solution: The light needs to be adjusted in time. It is best to place it in a semi-sunny place and receive appropriate sunlight. 3. Insufficient wateringReason: If there is insufficient watering and the soil in the pot is too dry, the plant will have yellow leaves due to lack of water. Solution: Water the plant thoroughly first, and then place it in a cool place for maintenance. Wait until it recovers, then carry out daily fertilizer and water management. 4. Too little fertilizerReason: The soil fertility of the maiden heart grown in potted plants is limited. If there is a lack of fertilizer for a long time, it is easy to suffer from malnutrition, causing the leaves to turn yellow and fall off. Solution: Top dressing is needed in time. In the following period of time, more topdressing will be needed. But be careful not to use too much fertilizer or it will harm the plants. 5. The potting soil is not replaced in timeReason: The nutrients in the potting soil will continue to be consumed. If the soil in the pot is not changed for a long time, the soil in the pot will not have enough nutrients, resulting in insufficient supply of nutrients needed for plant growth, which will cause the plant to turn yellow and lose leaves. Solution: The potting soil needs to be replaced in time. Try to replace the potting soil every 1-2 years. The best time to replace the potting soil is on a sunny day in spring and autumn when the temperature is suitable. During the replacement process, the roots can be trimmed appropriately. |
