Chinese evergreen growing methods

Light management

Chinese evergreen likes bright light and a well-ventilated environment. In spring, the illumination is controlled at 15,000-20,000 Lux; In summer, due to the high temperature, high temperature and humidity, shading and ventilation should be strengthened. It is ideal to control the lighting in the range of 10,000-15000LUX. In autumn and winter, the temperature is lower, and the illumination is controlled to 20,000-30000Lux or full sunshine. Too strong light leaves will be yellow and green, too much shade will be very long, prostrate, affect the ornamental effect.

Temperature management

Chinese evergreen like high temperature, not cold resistant, suitable temperature for growth 20-30℃. The lowest overwintering temperature is above 12℃. Once affected by the cold leaves yellow wilting, terminal bud necrosis.Winter maintenance needs heating equipment. If there is no heating facilities, it can use double insulation facilities, winter afternoon in the temperature drops to 22-24℃ to seal the shed in time (the north of the general greenhouse to seal, the south of the greenhouse can be appropriate to leave some space, to facilitate the air flow in the shed, the control of humidity in the shed is too large). In summer, if you use a simple shed for planting, the film should be lifted on sunny days, and the roof of the shed should be covered with a layer of shading net with a density of 75%. A layer of 50% shading net can be added in the shed, so that it can be used for ventilation and cooling. But in continuous overcast rainy days to cover the film, prevention and control rain too much to cause the matrix in the basin long-term too wet and cause rotting root, rotten stem phenomenon. In summer we can strengthen shade and ventilation.

Moisture management

Chinese evergreen likes high temperature, high humidity, half shade or shade environment, and humidity can be maintained at 60%-70%.

Disease control of Chinese evergreen

Disease control

Leaf spot

At first, the disease spot is a small brown spot, and the surrounding water - impregnation faded green, and a wheel - striated expansion, round to oval, brown inside the edge of gray white. In the late stage, dark brown mildew appeared in the center of the lesion, which turned into dark brown mildew layer under humid conditions. The method to prevent and cure this disease is to remove the diseased and residual leaves in time. With 800 times of mancozeb prevention and treatment, once a week, continuous 3-4 times.

Anthrax

It mainly occurs on leaves, but can spread to petioles in severe cases. In the early stage, the lesions were water-impregnating yellow macules, and after expansion, they were oval to irregular brown or yellowish brown, slightly wheel-striated. In the late stage, the lesions were connected into a piece of dry, and small black spots with wheel-striated arrangement were produced. This kind of disease is mainly because ventilation is not good, when there is scale insect harm advantageous disease occurrence. The methods of prevention and control of this disease are to strengthen conservation, increase phosphorus and potassium fertilizer; At the beginning of the disease we can use 1000 times chlorothalonil to prevent and control, once a week, 3-4 times.

Pest control

Starscream

Air humidity is dry, easy to occur on the bottom leaves and dead leaves. We can use carmite 2000 times.
