Sandy loam is the best way to cultivate fragrant roots. Whether planted in the ground or in a pot, sandy loam with good drainage and high fertility is better, and saline-alkali land is avoided. Potted plants should be covered with a layer of broken bricks at the bottom of the basin to facilitate ventilation and drainage. Transplanting or turning over pots to change soil should be carried out after the flowers wither. Before the new leaves unfold, bring soil balls to avoid affecting the next year's flowering. Water and fertilization should be moderate. It is best to water regularly during the growing season to keep it slightly wet. Accumulated water is easy to rot roots, and it is easy to fall leaves if it is too dry, resulting in less spring flowers in the next year. After flowering, apply a fertilizer mainly containing nitrogen fertilizer to promote the growth of branches and leaves, and apply a compound fertilizer mainly containing phosphorus and potassium fertilizer in autumn to promote the differentiation of flower buds, and do not apply fertilizer at other times.
Sexual preference for semi-humid sun protection, aromatic semi-cloudy, can be planted or placed in the south of the back wall. It is best to avoid the scorching sun in midsummer and bask in the sun in winter. Potted plants should be placed in sunny places from autumn to spring and in semi-cool places in summer. Over-sun leaves tend to turn yellow and have few flowers; If it is cloudy, the flowers will fade.
Sweet temperate tree species like warm and cold, like warm climate, and can withstand freezing below -20℃. It can overwinter outdoors in the south of Beijing, but the flowering period will be postponed from March to April in the place of-10℃ to -20℃ in winter, and it is only suitable for potted plants in the place below -20℃ in winter and placed on the south window sill in winter.
Cutting by ramets is easy to propagate, which makes the fragrant wood loose. After 10 years of cultivation, it will age, so we should pay attention to propagating new plants instead. All cuttings are easy to survive. Dividing plants can be combined with turning over pots and filling soil, and at the same time, the roots of the seedlings sprouting from the roots of the mother plants can be cut off and planted separately. When the ground temperature is above 15℃, select the middle and lower parts of robust annual branches, cut them into cuttings of about 15 cm, insert them into the soil of 1/3 ~ 1/2, water them in the shade, spray water frequently to keep warm, take root in about 50 days, and plant them in the next spring. It is better to divide plants for family reproduction, and you can see flowers next spring. Cutting in the flower field is better and the propagation coefficient is large, but flowers can't be seen until the third year.
