Lime wood is an evergreen shrub or small tree of Malus in Loganiaceae, with a height of 5 ~ 12 m and a trade name of African jasmine. Because the homonym of flower pear wood is similar to jasmine, and in order to make the name sound good and sell well, the flower shop gave it a new name, African jasmine. The other names of Huahui Wood are Huihui Wood, Huihui Wood and Huangguo. The leaves are fleshy, green and shiny, and the color is white or slightly yellow. The inflorescence is erect and terminal, and the flowers are fragrant and elegant. In frost-free areas, they are excellent green flowers and trees and can also be used for hedge cultivation. In the northern region, potted plants are the main ornamental plants, and most of them are placed on both sides of the unit gate during the growing period.

(1) sow and raise seedlings. The fruit is mature and oval in autumn and winter, and can be sown directly after seed collection. Make a seedbed in the open space and cover it with soil for 2 ~ 3 cm after sowing. The ground is covered with straw to prevent moisture and cold. Seeds sown in late autumn and early winter will not germinate until spring. Or hide the seeds in the sand and sow them after the cracks in the seeds are exposed in spring. After emergence, straw should be removed, water and fertilizer management should be strengthened, and summer seedling stage should be shaded.

(2) Cutting propagation. Cutting propagation can be carried out throughout the growing season, and summer is the most conducive to rooting. Use 1 ~ 2-year-old robust branches as cuttings, with the length of 12 ~ 15 cm, leaving 2 ~ 3 leaves on the upper part, and cutting off 1/2. It is more suitable to cut the lower end of cuttings at 0.2 ~ 0.3 cm below the node. Use sand or peat soil as cutting medium. Shade and moisturize after cutting, and the temperature is suitable for rooting 1 month.

(3) Propagation by ramets. Some roots near the ground will grow buds, and the buds will be cut off with the roots to become new plants. In spring, when the plants just germinate, separate them, cut them with a sharp knife at the weak root joint, and take the separated plants out of the flowerpot or dig them out of the ground. Each newly divided plant should have a part of complete root system.

(4) Layered propagation. The middle and lower parts of the 2-3-year-old robust branches germinated at the base are peeled or scratched, buried in the soil, and take root in 40-50 days. Or peel off 2-year-old robust branches at the position about 0.5 cm below the internode, the width of which is about 3 times the thickness of the branches, and air layering takes root for 2 ~ 3 months. Seedlings propagated by various methods should be cultivated in a warm, humid and well-ventilated environment. The soil should be loose, moist, fertile and well drained. The light should be sufficient to avoid direct light.
