What to do when camellia leaves turn yellow? After repotting, the leaves grow large and green again
Yellowing camellia leaves need to be addressed according to the cause: if it is a lack of fertilizer, then fertilizer should be supplemented appropriately; if the watering is unreasonable, then water correctly, and it is best to keep the potting soil slightly moist at ordinary times; if the soil quality is poor, then the soil should be changed in time, and the pot should be changed at regular intervals; if it is caused by pests, then the pests should be removed in time.
1. Supplement fertilizer
Yellowing leaves are very likely caused by insufficient fertilizer or some element it needs. At this time, we should supplement fertilizer and the other elements it needs in time. Generally speaking, applying bean cake water about once a month is enough. It is worth noting that the bean cake water must be fully decomposed, and the concentration must not be too high. In addition, adding a 1% ferrous sulfate solution when watering can not only effectively supplement the elements the flower needs but also keep the soil slightly acidic.
2. Water reasonably
Its leaves turning yellow is very likely because the watering is not reasonable enough; too much or too little water can both cause yellow leaves. When watering, we should note that we cannot water too much at one time and let water accumulate in the pot, nor can we go a long time without watering and let the soil become too dry. It is best to keep the potting soil slightly moist at ordinary times.
3. Change the soil quality
Its leaves turning yellow may be caused by poor soil properties. Camellias relatively prefer to grow in slightly acidic soil; if the soil becomes alkaline, it may cause their leaves to turn yellow. In addition, the loss of nutrients in the soil can also cause their leaves to turn yellow. At this time, we should change the potting soil for the flower at regular intervals, and we can also reasonably apply foliar fertilizer to prevent its leaves from turning yellow.
4. Eliminate pests in time
When growing this kind of flower, red spider mites are a pest often encountered, and the presence of these insects is very likely to cause its leaves to turn yellow. At this time, we should eliminate these insects in time. Spraying the leaves with a 50% parathion solution is a good choice. Besides red spider mites, scale insects may also be encountered, and scale insects can also be killed by spraying with a specialized pesticide. Therefore, observe more in daily care, and eliminate pests in time once they are found.
