Chimonanthus praecox, also known as Chimonanthus praecox, is a deciduous or semi-evergreen shrub of Chimonanthus in Chimonanthaceae. Chimonanthus praecox is called plum blossom, but it is not actually plum blossom. Because its flowers are similar to plum fragrance and shape, waxy yellow, and generally bloom in the twelfth month, it is named wintersweet. After the seeds mature in August, they can be stored in dry storage, sown in the next spring, and soaked in warm water for two days before sowing, so that the seedlings can emerge orderly. If the planting management is moderate, it will start to bloom in 3 ~ 4 years.

The plant height of Chimonanthus praecox planted underground can reach 4 ~ 5 meters, the root neck is developed, and it often forms a fat root disk, which is strong, leafy and resistant to pruning, so there is a saying that Chimonanthus praecox does not lack branches. In order to cultivate potted Chimonanthus praecox with well-proportioned and beautiful plants, it is necessary to keep shaping and pruning from childhood, leaving only 3 ~ 5 main branches evenly distributed per plant, controlling the branches at 10 ~ 20cm, with thick branches and many flowers. Chimonanthus praecox likes light and is more resistant to shade and cold. The ground should be planted in the leeward and sunny place, and it can safely overwinter when the temperature is not lower than-15℃. I like the slightly acidic soil with deep soil layer, loose and fertile soil and good drainage. I am resistant to drought and waterlogging, and I am afraid of dry wind intrusion. The bottom of potted plants should be padded with coarse sand as drainage layer and planted with slightly acidic sandy soil containing humus and a small amount of base fertilizer. During the growth period, organic liquid fertilizer and compound chemical fertilizer solution are applied alternately every half month.
