The camellia leaves are yellow again? Put it in a new pot and make it big and green.

Yellow camellia leaves need to take countermeasures: if it is less fertilizer, it is necessary to replenish fertilizer properly; if watering is unreasonable, it is necessary to water correctly, and it is best to keep the potted soil slightly moist on weekdays; if the soil quality is not good, it is necessary to change the soil in time and change the basin regularly; if it is because of insect pests, it is necessary to remove the pests in time.

I. replenishing fertilizers

The yellowing of the leaves is most likely caused by the lack of fertilizer or some element it needs. At this time, we should replenish the fertilizer and other elements it needs. Generally speaking, bean cake water should be applied once a month or so. It is worth noting that bean cake water must be rotten and its concentration should not be too high. In addition, adding 1% ferrous sulfate solution during watering can not only effectively supplement the elements needed by flowers, but also keep the soil slightly acidic.

Second, rational watering

The yellowing of its leaves is probably due to unreasonable watering, and too much or too little water may cause its yellow leaves. When watering, we should be careful not to water too much at one time, so that there is stagnant water in the basin, nor can the soil be too dry without watering for a long time. It is best to keep the basin soil slightly moist on weekdays.

Third, change the soil quality

The yellowing of its leaves may be caused by the poor properties of the soil. Camellia prefers to live in acidic soil, which may cause its leaves to turn yellow if the soil is alkalized. In addition, the loss of nutrients in the soil will also cause the yellowing of its leaves. At this time, we should regularly change the potted soil for the flowers, and we can also reasonably apply foliar fertilizer to prevent its leaves from turning yellow.

IV. Timely elimination of insect pests

When raising this kind of flower, we often encounter the pest of red spider, and the existence of this kind of insect is likely to cause its leaves to turn yellow. At this time, we must eliminate these bugs in time. Spraying leaves with 50% parathion solution is a good choice. In addition to red spiders, it is also possible to encounter scale insects, which can also be sprayed with special agents. Therefore, more observation should be made every day, and once pests are found, they will be eliminated in time.
