What to do when camellia leaves turn yellow? Find the cause and treat it accordingly

1. Supplement fertilizer

Yellowing leaves are very likely caused by insufficient fertilizer or a certain element it needs. At this time, we should promptly supplement fertilizer and the other elements it needs. 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 its leaves to turn yellow. When watering, we should note that we cannot water too much at one time, causing water to accumulate in the pot, nor can we go a long time without watering, causing the soil to become too dry. It is best to keep the potting soil slightly moist on ordinary days.

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 its leaves to turn yellow. In addition, the loss of nutrients in the soil can also cause its leaves to turn yellow. At this time, we should regularly replace the potting soil for the flower, and can also reasonably apply foliar fertilizer to prevent its leaves from turning yellow.

4. Eliminate pests promptly

When growing this flower, you will often encounter the pest red spider mite, and the presence of this insect is very likely to cause its leaves to turn yellow. At this time, we should promptly eliminate these insects. Spraying the leaves with a 50% parathion solution is a good choice. Besides red spider mites, you may also encounter scale insects, and scale insects can also be killed by spraying with a special pesticide. Therefore, observe more in daily care, and eliminate pests promptly once they are found.
