Propagation method: Cuttings are commonly used for propagation. Generally during the plum rain season, select mature one-year-old branches 15-20 cm long as cuttings, preferably with a bit of the previous year's wood at the base. The substrate should be loose and well-drained. After inserting the cuttings, cover with plastic film, then build a shade frame above it, keep the seedbed moist, ventilate morning and evening; roots form in about 20 days, and after growing in the bed for 1 year, they can be transplanted. Seed propagation is also possible; seeds should be sown immediately after collection. Since it is dioecious, seed propagation requires artificial pollination, or planting male and female plants adjacent to each other. In the

Propagation method: Cuttings are commonly used for propagation. Generally during the plum rain season, select mature one-year-old branches 15-20 cm long as cuttings, preferably with a bit of the previous year's wood at the base.

After inserting the cuttings, cover with plastic film, then build a shade frame above it, keep the seedbed moist, ventilate morning and evening; roots form in about 20 days, and after growing in the bed for 1 year, they can be transplanted. Seed propagation is also possible; seeds should be sown immediately after collection. Since it is dioecious, seed propagation requires artificial pollination, or planting male and female plants adjacent to each other. In the middle and lower reaches of the Yangtze River, seeds are not easy to collect, so this method is rarely used.

Transplanting is best done in spring or during the rainy season; a soil ball must be kept, sufficient base fertilizer should be applied before planting, and care should be strengthened after planting, keeping the environment shady and moist at all times; after three to five years it will produce a greening effect. Because Aucuba stops growing relatively late, it is susceptible to early frost damage.

In addition to choosing a warm, humid, shaded spot with relatively good microclimate conditions for cultivation, no more fertilizer should be applied after September, to improve its cold resistance. North of the Yangtze River it is mostly grown in pots, especially Aucuba japonica 'Variegata'; because it is extremely shade-tolerant, it is very suitable for home care. In care, the potting soil should be loose and fertile, watering should be timely, the environment should be humid, and freezing must be prevented in winter. It is a foliage plant that is low-maintenance and easy to grow.

Potted Aucuba can be placed on a balcony or indoors. If placed outdoors, prevent exposure to scorching sun in summer, and also keep the soil moist and provide shade; otherwise, the leaves are prone to scorching. If there is a continuous rainy season or the air is hot and stuffy, be sure to pay attention to drainage and ventilation, otherwise the branches and leaves are prone to southern blight. The size of the pot should match the size of the plant. A soil mix of 2 parts garden soil, 1 part leaf mold and 0.5 part chaff ash is better as a growing medium. Transplanting is best done in spring or during the rainy season. During the growing season, apply 20% decomposed cake fertilizer water or human waste once a month, and in autumn apply phosphorus and potassium fertilizer 1-2 times; in this way, the leaves can be made glossy dark green and more ornamental.
