Originating in China and Japan, it is distributed in parts of South China, Southwest, Central China, East China and Northwest China. There are many cultivation applications in this area.

Ecological habits:

Neutral tree, slightly shade-tolerant, adaptable, hi warm, moist climate, intolerant to drought and barren, strict requirements on the soil, suitable for deep fertile slightly acidic soil or slightly alkaline soil, still cold. Scallops are well developed, grow fast, have strong sprouting ability, and are resistant to pruning. Strong anti-pollution.

Privet can be used for sowing and cutting seedlings. Sowing seedlings should be sowed immediately after winter sowing, and the stone fruit will not be treated in any way.

If sowing in the spring of the following year, the stone fruit should be soaked in water to remove the skin, washed and dried, and stored in layers with wet sand. If it is not sun dried in the sand, the germination rate is low and it takes a summer to emerge. Therefore, it is better to use winter sowing, which can not only emerge earlier, but also have higher germination rate and emergence rate than spring sowing.

When planting, sowing or seeding is commonly used. The thickness of the cover soil is 1 to 1.5 cm. After sowing, the grass is covered. The seedlings will emerge in spring next year and the plant height can reach 50 cm.

As an ornamental street tree, it is necessary to cultivate high-stemmed plants, close planting at the seedling stage, pruning and shaping, and then changing into a big seedling, and then leave the garden after four or five years.

As hedgerow planting, the garden can be planted in winter.

Ligustrum fine wood, for the fine woodworking timber. Fruit Ligustrum lucidum is a traditional Chinese medicinal material that has the effect of supplementing liver and kidney. The privet twigs are carried out, the crowns are inverted oval, the summer flowers are fragrant, and the winter is frost-bearing. It is a common garden ornamental tree. Horticultural workers use privet as rootstock and sweet-scented osmanthus as scion to graft and cultivate “Four Seasons Gui”.

China's white wax is one of the world's leading specialty products. Privet trees can be stocked with white wax insects, producing white wax, so it is also known as "water wax tree." The wax has a high melting point and is not easily melted in the tropics or under high temperatures. It can be used as a vessel sealer, silk polisher, and a pill coat, which has a high economic value.

Ligustrum is also a good tree species to reduce noise. Osaka Airport, Japan, has planted nearly 4,000 privets and cedars on both sides of the runway to reduce noise and reduce noise by 10 decibels.
