Osmanthus is also known as rock osmanthus. It is one of the top ten famous traditional flowers in China, integrating greening, beautification, and fragrance into an ornamental garden species.

Osmanthus Tree Planting Methods:
1. Choosing soil is the first step, and also the most important one. The requirements for the planting soil of osmanthus trees are slightly acidic and avoiding alkaline soil. For potted osmanthus, a sandy soil with a deep, loose, and fertile layer and good drainage can be used. Mix decayed leaf soil, garden soil, sandy soil, and decomposed cake fertilizer in a ratio of 2:3:3:2, then plant in the pot.
2. newly planted osmanthus trees must be watered to maintain humidity in the air, but osmanthus trees are not tolerant to flooding, so avoid waterlogging. In northern winter, potted osmanthus should be kept in a well-ventilated and well-lit indoor environment, with less watering. After April, water can be increased appropriately.
3. In summer, osmanthus trees can be fertilized once with phosphorus and potassium fertilizers, which is beneficial for flower and leaf growth. After entering winter, an organic fertilizer can be applied, mainly decomposed cake fertilizer, and concentrated fertilizers should not be used. Fertilization should follow the principle of "frequent application of thin fertilizers," mainly using fast-acting nitrogen fertilizers and fertilizing according to the growth condition of the osmanthus. For newly planted osmanthus, avoid early top-dressing to prevent root damage.
4. Osmanthus trees prefer to grow in a warm environment, with an average temperature of 14-28°C, and should not be below 8°C in winter. Annual humidity is best maintained at 75%-85%.
5. Osmanthus trees should be moved indoors in winter and placed in a sunny location to receive light. In summer, when the sun is strong, they should be shaded, and they need sufficient sunlight during the growing period to avoid bud differentiation.
6. The main diseases of osmanthus trees are brown spot andwithered spot. A 1:2:200 dilution of Bordeaux mixture can be sprayed. It is necessary to clean up the diseased leaves and remove them promptly.
7. Prune osmanthus trees in time, cutting off diseased branches, withered branches, and overly long branches.
