What s going on with camellia yellow leaves falling off their leaves?

There are many reasons for the yellowing of camellia leaves, including maintenance and management factors, as well as physiological factors. The yellowing or whitening of leaves occurs in summer because the soil is deficient in nutrients such as phosphorus, iron, or sulfur, so it can be cultivated with humus-rich mountain mud by changing the potting soil. From April to September, every 15 days, foliar sprays with 300 times diluted ferrous sulfate solution or trithionphos solution can alleviate the symptoms.

Spraying should be done on cloudy days and early morning or late afternoon on sunny days. If the nitrogen element ** is insufficient, there will also be yellowing of the leaves, you can apply rotted bean cake water, once a month, the ratio of fertilizer to water is 20 to 30. If you add 1 more person.

Ferrous sulfate solution in fertilizer solution, the effect is better. If not watered properly, persistent drought or excessive humidity can also cause yellow leaves. If the potting soil is too wet, the root system of the plant will turn black and rot, causing the leaves to turn yellow and fall off.

On hot and sunny days, although the plants are shaded by curtains, the potting soil is often dry, which will also cause the leaves to turn yellow and fall off. Rubikite spiders or scale insects can also cause yellowing of leaves. Red spiders can be sprayed with 25 dimethoate with water 1000-1500 times, or 50 dimethoate with water 2500 to 3000 times; Scale insects can be sprayed with 5 dimethoate aqueous solution.

Camellia is an evergreen tree, the leaves do not fall off 2-3 years after the formation of new shoots, but in the leaf-changing period of April to May, a small number of old leaves will also turn yellow and fall off, which is a normal phenomenon.

Camellia often leaves yellow leaves, don't panic, the solution is very simple, just avoid a few thunders.

Why do the camellias you raise often lose their leaves? It may be caused by these reasons, and we must pay attention to maintenance.

Camellia yellow leaves are due to excessive watering, soil discomfort, lack of nutrients, normal metabolism, camellia is suitable for planting in loose and fertile, good drainage, rich humus acidic soil, usually put it in the semi-shade, avoid strong light exposure in summer, watering should be diligent, but the amount can not be much, keep the soil moist, do not have stagnant water, and apply a rotten soybean cake water once a month.

Camellia yellow leaf cause.

1. Overwatering

Camellia tea likes a moist environment, but too much watering can easily cause water accumulation in the soil, and the roots will rot when soaked in water, resulting in yellow leaves.

2. Soil discomfort

Camellia is suitable for growing in acidic soil, if the soil is alkaline or the soil nutrients are gradually lacking, so that it lacks nutrients, it is easy to cause yellowing of leaves.

3. Lack of growth elements

Camellia will need some growth elements during normal growth, and if nitrogen is lacking, there will be yellow leaves and leaf loss.

4. Normal metabolic phenomena

Camellia is an evergreen plant, and its leaves generally do not fall off in a short period of time, but there may also be leaf changes, when the leaves will turn yellow, which is a normal phenomenon.

What to do if the camellia leaves are dropped.

Method 1If the yellow leaves of camellia are caused by excessive watering, first suspend watering, then turn the soil, put it in a well-ventilated and cool place for a period of time, and then slowly recover, and then water appropriately.

Method 2If the yellow leaves of camellia are unsuitable for the soil, they should be regularly replaced with acidic and humus-rich soil, and before changing for new soil, the new soil needs to be exposed to the sun for a few days to prevent the occurrence of pests and diseases.

Method 3If the yellow leaves of camellia are caused by normal metabolism, no special treatment measures are required, normal maintenance can be, if it is caused by the lack of maintenance of this noisy stool, it can be supplemented with the required nitrogen elements, and you can apply a rotten soybean cake water or add 1% ferrous sulfate solution once a month.

Prevent the yellow leaves of camellia from falling off.

Camellia is suitable for planting in loose and fertile, well-drained soil, usually put it in semi-shade, avoid strong light exposure in summer, provide long-term light in autumn and winter, can promote flower bud differentiation, usually watering to be diligent, but the amount can not be much, keep the soil moist, do not have water.

Causes of yellow leaves of camellia: excessive watering, soil discomfort, normal metabolism.

1. Too much watering: Camellia tea likes a humid environment, but too much watering can easily cause water accumulation in the soil, and the roots will rot when soaked in water, resulting in yellow leaves. First pause watering, then turn over the soil, put it in a well-ventilated and cool place for a period of time, then slowly resume, and then water moderately.

2. Soil discomfort: Camellia is suitable for growing in acidic soil. If the soil is alkaline or progressively lacking in soil nutrients, it can easily cause the leaves to turn yellow.

Acidic and humus-rich soils should be replaced regularly. The new and disturbed soil needs to be exposed to sunlight for a few days before being exchanged for new soil.

3. Normal metabolism: Camellia is an evergreen plant, and its leaves generally do not fall off in a short period of time, but there may also be leaf changes, and the leaves will turn yellow at this time, which is a normal phenomenon. No special treatment measures are required and can be maintained normally.

If there is a lack of nutrients, the required nitrogen can be supplemented. Cooked soybean cake water or a 1% ferrous sulfate solution can be applied monthly.

Growing environment

Camellia is afraid of wind and sun, high terrain, air circulation, warm and moist, well-drained, loose and fertile sandy loam, loess or humus. The pH is optimal. The suitable temperature is between 20 and 32, and the growth stops when it is above 29, and the leaves will be wide and scorched at 35, requiring a certain temperature difference.

The ambient humidity is more than 70%, most varieties can tolerate 8 low temperatures (natural wintering, cloud tea is slightly not cold-tolerant), and in the area south of the Huai River, it can generally naturally overwinter acidic soil, and requires good air permeability. Camellia can be shaded in spring, autumn and winter, and can be treated with 50% shading in summer.

Transfer the camellia to a well-ventilated area, stop watering, and remove the yellow leaves from the plant.

1. Long-term drought: Reason: If the camellia is not watered for a long time or forgets to water, the potting soil is too dry, and the leaves of the plant will be yellow and dry when they are out of water, and they will fall off when touched.

Remedy: Hydration should be given in time to encourage the plant to return to normal metabolism and grow new leaves. 2. There are many reasons for watering:

Raised in a closed room, the ventilation is not good, but the watering is too diligent. After the camellia is raised for a period of time, the leaves will turn yellow, brown and black spots appear, and if you do not adjust the watering, the leaves will slowly turn yellow and dry up. Remedy:

Transfer the camellia to a well-ventilated area, stop watering, and remove the yellow leaves from the plant. After a period of repair, the root system will slowly return to normal. 3. Poor ventilation and poor environmental conditions

Many flower friends will keep camellia indoors, but often ignore the ventilation and light conditions are not suitable, resulting in poor maintenance environment, poor growth of camellia, yellow leaves, dead leaves. Remedy: Transfer the camellia to a well-ventilated, brightly lit place to maintain, remove the dry, yellowed leaves, and let the plant recover on its own.

4. Reasons for environmental mutations: The newly bought camellia suddenly changed to a new environment, and there was no way to adapt to the world for a while, and there may be some yellow leaves and dead leaves. Remedy:

Try to put the new camellia in a scattered light place first, and do not expose it to the sun or put it in a dark place all at once. If only a small amount of yellow leaves and fallen leaves appear, it is normal and does not need special treatment. 5. Causes of violence:

If the newly bought camellia is directly taken to remove the pot and soil, wash the roots, and after repotting, due to the damage to the root system, the leaves cannot absorb enough water, and the leaves will turn yellow and wither, and all the leaves will fall off in serious cases. Remedy: The leaves and branches of the plant are thinned to reduce the consumption of water and nutrient lead, and reduce the burden on the plant.

If the plant is more vigorous, it will re-germinate later. It is recommended that the newly bought camellia should not be taken to wash the roots at once, as it is easy to have a large number of fallen leaves.
