1. Supplement fertilizerThe yellowing of leaves is most likely caused by insufficient fertilizer or certain elements it needs. At this time, we should add fertilizer and other elements it needs in time. Generally speaking, it is sufficient to apply bean cake water once a month or so. It is worth noting that the bean cake water must be decomposed and the concentration cannot be too high. In addition, adding 1% ferrous sulfate solution when watering can not only effectively supplement the elements needed by flowers but also keep the soil slightly acidic. 2. Reasonable wateringThe yellowing of its leaves is most likely due to improper watering. Too much or too little water may cause yellow leaves. When watering, we must be careful not to water too much at one time, causing water accumulation in the pot, nor to not water for a long time causing the soil to become too dry. It is best to keep the soil in the pot slightly moist on weekdays. 3. Change the soil qualityThe yellowing of its leaves may be caused by poor soil quality. Camellia prefers to live in acidic soil. If the soil becomes alkaline, its leaves may turn yellow. In addition, the loss of nutrients in the soil can also cause its leaves to turn yellow. At this time, we need to change the potting soil of the flowers regularly, and we can also apply foliar fertilizer reasonably to prevent the leaves from turning yellow. 4. Eliminate pests in a timely mannerWhen growing this kind of flower, you will often encounter pests such as red spider mites. The presence of this insect is likely to cause its leaves to turn yellow. At this time, we must eliminate these insects in time. Spraying the leaves with a 50% solution of trithion is a good choice. In addition to red spider mites, you may also encounter scale insects, which can also be killed by spraying with special pesticides. Therefore, we should observe more frequently on a daily basis and eliminate pests in time once they are found. |
