1. Light: Fatsia japonica needs moderate light, but it cannot be directly exposed to strong light. In winter, it can be directly exposed to the sun. In other seasons, it should be shaded or put under the astigmatism. It is necessary to keep enough light time, otherwise the leaves will be very small.
2. Soil: Fatsia japonica requires good drainage. Add proper amount of base fertilizer in basin soil, plant with humus soil, you can add river sand to enhance its water permeability.
3. Watering: the watering of Fatsia japonica varies according to the temperature. In summer and early autumn, when the temperature is high, it needs to be watered frequently and watered for humidification. After October, we should reduce watering to avoid frostbite.
4. Fertilization: Fatsia japonica needs a large amount of fertilizer in the period of vigorous growth. Generally from the middle of spring to the first ten days of autumn, thin liquid fertilizer should be applied twice a month. But other time forbid fertilization, otherwise it will hurt the root.
Cuttage, sowing and plant division are commonly used in propagation. The cutting is carried out in autumn, and the two-year-old branches of 15 cm long are selected to be inserted into the basin soil, and then the water can be poured. The seeds are sown in spring, washed and sown in the soil, covered with grass to keep moisture, and germinated within 30 days. The ramets are also carried out in spring, and the original plants are divided into several plants, which can be maintained in the shade for 2 weeks.
1. Diseases: common diseases include bituminous coal disease, leaf spot disease and yellow disease. At ordinary times, we need to pay attention to ventilation and apply fertilizer on time, which can effectively enhance the resistance. Spray chlorothalonil and other pesticides to treat the disease.
2. Insect pest: aphids, scale insects and spider are common. For different pests, use corresponding pesticides to control.
