1. Sowing: after the fruit is ripe in autumn, harvest it, grind off the pericarp, wash it clean, use wet sand to accelerate the germination of seeds in layers at low temperature, and sow it before March of the following spring. Seedling growth is slow, so it should be carefully maintained and managed. Holly seeds usually germinate every other year if they don't germinate.
2. Cutting: In rainy season, it is advisable to use tender cuttings, the length of which is 6-8 cm. Cut off the lower leaves, leaving only L-2 leaves and short cuttings, and the cutting depth is 1/2. After cutting, it is necessary to use sandy soil as the substrate, build a shed for shade, spray water frequently to keep moisture, and take root after about 1 month.

3.？ Management: After the seedlings are cultivated in the nursery for 2-3 years, they can be transplanted and planted. Transplanting should be carried out in spring, and roots should not be damaged when digging seedlings, and seedlings should be transplanted with soil. Attention should be paid to weeding in intertillage, watering when dry and strengthening management. Holly is easy to be affected by ash medium, with dense branches and leaves, and soot disease is easy to occur between burnt skins, so attention should be paid to timely prevention and control.
Holly is suitable for planting in humid and semi-cloudy places, likes fertile soil and can grow well in general soil, and has no strict requirements on the environment. The seedlings planted in that year can grow naturally by watering once, and watering once every 15 days according to the soil moisture. Combined with intertillage weeding, topdressing 1 ~ 2 times a year in spring and autumn is appropriate, and dilute liquid fertilizer mainly containing nitrogen fertilizer is generally applied. Holly sprouts and grows branches many times a year, which is extremely resistant to pruning. It should be pruned once in summer, and it can be pruned into a flat shape or a spherical shape or a conical shape in autumn according to different greening needs, and the branches should be properly thinned to maintain a certain crown-shaped branching state. Measures such as piling up soil to prevent cold can be taken in cold places in winter. Leaf spot is the main disease of Ilex, which can be controlled by carbendazim and chlorothalonil.
Cuttings of Ilex are mostly carried out in May-June. First, we can cut obliquely from the middle and upper part of the crown, take 5 ~ 10 cm long and vigorous lateral branches to cut off the lower leaflets, and keep all the upper leaves. Then it is treated with rooting powder, cut off and cut into seedbeds. The seedbed should be selected in a ventilated and shade-tolerant place, or it can be cut in shade, with high survival rate.
