What to do if Camellia sasanqua leaves fall off

reason

Improper lighting

Although Camellia sasanqua prefers warm environment and sunlight, it cannot tolerate strong sunlight exposure. If it is placed in direct sunlight during its growth period, it will affect its growth and cause its leaves to fall off. The strong sunlight in summer will burn the leaves and buds, causing the leaves to curl, burn and fall off.

However, if the camellia sasanqua is placed in a dark environment for a long time and does not receive sunlight, it will not be able to carry out photosynthesis and its leaves will fall off.

Improper watering

Camellia sasanqua prefers shade and humidity, and grows best in a semi-shady environment, but improper watering is also the key to the healthy growth of Camellia sasanqua.

Too little watering can cause the soil to dry out, which can cause the branches and leaves to dry out and fall off.

Excessive watering will cause water accumulation, which will affect the breathing of the camellia roots and also affect the growth of the leaves.

Overfertilization

Especially for the one- or two-year-old camellia sasanqua seedlings, the roots are tender and weak, and concentrated fertilizers cannot be applied. Excessively concentrated fertilizers will burn the roots of the camellia sasanqua, causing the leaves to fall off, and in severe cases, even lead to the death of the plant.

what to do

Proper shade

Since the newly planted Camellia sasanqua cannot withstand the cold wind and sun in early spring, it should be placed outdoors in a windproof, warm, semi-shaded place.

If it is cold outside, it should be placed in a place with diffuse light indoors. As the temperature rises, the pot can be gradually placed outdoors.

As the temperature continues to rise, the pot can be placed on the north windowsill of the south room or the balcony of the north room around noon, receiving only the morning sun and the evening sun, and avoiding direct sunlight around noon. In summer, it should be placed under the eaves or under the shed in the yard.

Watering

For newly transplanted or just-mailed camellia sasanqua seedlings, after watering them sufficiently for the first time, do not water them again as long as the soil in the pot is not dry. Spray water on the plants and the pot surface 2-3 times a day to keep the soil in the pot slightly moist. This ensures that the leaves are not short of water, without making the soil in the pot too wet.

Normally water when the soil is dry and water thoroughly.

Light fertilization

Generally speaking, apply a thin layer of nitrogen fertilizer once from February to March to promote the growth of branches and leaves.

Apply a thin layer of cake fertilizer water once between April and May to facilitate flower bud differentiation.

Apply 0.2% potassium dihydrogen phosphate once from September to October to promote large and colorful flowers.

In order to maintain the appropriate acidity of the potting soil, you can combine fertilization with watering with alum fertilizer or water soaked with grass.
