Aglaonema commutatum Pseudo-bracteatum White

Growing environment

Half Yin resistance, death day light is too strong, but the light is too dark, will also lead to leaf fading.

Like water wet, March - August growth period to water more. In summer, water should be sprayed frequently to increase the humidity of the environment.

Like high temperature, not cold, growth suitable for temperature 20-30℃. The lowest overwintering temperature is above 12℃.

Cultivation technique

Initial management

Maintenance to keep the substrate moist, March - August growth period to water more. In summer, water should be sprayed frequently to increase the humidity of the environment. Fertilizer should be applied in sufficient amount during the growth period to promote rapid growth. Fertilizer water should be applied once every two weeks from March to August. Reduce fertilization after autumn. Can use flower bud balance fertilizer 20-20-20 watering.

Sunshine management

Snow White rough ribwort likes bright and airy environment, light control is 15000 to 20000Lx in spring; In summer, due to high temperature, high temperature and high humidity, shading and ventilation should be strengthened, and illumination control at 8000-10000Lx is ideal. In autumn and winter, the temperature is low and the illumination is controlled to 20,000-30000lx or full sunshine. Too strong light leaves will be yellow and green, shading will be too long, lodging, affecting the ornamental effect.

Temperature management

Snow White rough ribwort likes high temperature, does not tolerate cold, the growth temperature is suitable for 25-30℃. The lowest overwintering temperature is above 13℃. Once frozen leaves yellow wilt, terminal bud necrosis, bottom leaf shedding. Winter maintenance requires heating equipment.

Humidity management

Snow White coyote is fond of high temperature, high humidity, semi-shade or shade environment, humidity is maintained at 60%-70%

Pest control

1. Leaf spot disease

High humidity weather, easy to happen. The lesion was initially small brown spots, the periphery was watered-like and faded green, and was wheel-shaped expansion, round to oval, the edge of the brown inner gray white. In the later stage, black and brown mildew appeared in the center of the plaque, which became black and brown mildew layer under humid conditions. The way to prevent and cure this disease is to remove the diseased leaves in time; Prevention with 800 times mancozeb, once a week, consecutive 3-4 times.

2. Anthrax

It mainly occurs on the leaves and can spread to the petiole in severe cases. At the beginning of the lesion, it is a small macula of water infiltration, and after expansion, it is an oval to irregular brown or yellowish brown, slightly wheel-shaped. At the later stage, the lesion is connected into a dry patch, and produces a wheel-shaped arrangement of small black spots. This disease is mainly due to poor ventilation, which is conducive to the occurrence of scale insects. The method of this disease is to strengthen conservation, increase the application of phosphorus, potassium fertilizer; At the beginning of the disease, 1000 times of chlorothalonil can be used for prevention and treatment, once a week, 3-4 times consecutively.

Special reminder

The whole plant is poisonous, do not ingest, ingestion will cause inflammation of the mouth, stomach pain, diarrhea, etc., should be treated at the hospital immediately.
