one. Cause Analysis1. Too many water supply times and water volume. Because of excessive watering, the new leaves turn yellow, but there is no obvious change in the old leaves. 2. Lack of water. If there is too much water, there will inevitably be a lack of water. Insufficient water will cause the old leaves below to turn yellow. Over time, the entire plant's leaves will turn yellow and then dry up and die. 3. Too much fertilizer. Too much fertilizer will cause the surface of new leaves to become bumpy and uneven. 4. Lack of fertilizer. Failure to fertilize on time will cause the plant to lack nutrients, the new leaves and tender stems will turn yellow, and the plant will die over time. 5. The plant is iron deficient. Indoor planting will make the soil unstable and change at any time, causing the leaves to become shriveled and yellow to varying degrees. two. Solution1. Watering problem: Water on time, control the amount and frequency of watering to avoid the leaves from drying up due to excessive watering or lack of water. 2. Fertilizer issue: Topdressing should be carried out on time and in the appropriate amount to avoid excessive application of fertilizer at one time causing plant deformities or long-term lack of fertilizer causing the plant to lack nutrients and cause yellowing of leaves. 3. Plant iron deficiency problem: Mix 7 parts of cake fertilizer and 5 parts of ferrous sulfate with water to make a diluted solution and water it on the plants to solve this problem. Summary: Be more careful in maintenance and fully understand its habits and growth environment. Maintain moisture in the pot while providing appropriate sunlight exposure. Also, pay attention to ventilation and sun protection when the temperature is high. In addition, the plants should be pruned regularly and the soil in the pot should be loosened and breathed. |
