How to Cultivate Osmanthus Trees for High Survival Rate
Introduction to the core of the text: This is an introduction to the related knowledge of how to cultivate osmanthus trees for high survival rates and the planting methods and precautions of osmanthus trees. Next, the editor will introduce them.
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 tree species. When osmanthus flowers bloom, they can be refreshingly dust-free and strongly fragrant, widely loved by everyone.
Planting Methods for Osmanthus Trees:
1. Choosing soil is the first step in planting, and also the most important step. The requirements for the planting soil of osmanthus trees are slightly acidic and alkaline-resistant. Potted osmanthus can use sandy soil with thick soil layer, loose fertility, and good drainage. Use decomposed leaf soil, garden soil, sandy soil, and decomposed cake fertilizer mixed in the ratio of 2:3:3:2, then mix well and plant in pots.
2. Newly planted osmanthus trees must be watered to maintain the humidity in the air, but osmanthus trees are not flood-tolerant, so avoid waterlogging. In northern winter, potted osmanthus should be paid attention to indoor ventilation and lighting, and less watering. After April, the water amount can be increased appropriately.
3. In the summer, osmanthus trees can be applied with phosphorus and potassium fertilizer, which is beneficial for flowering and lush leaves. After entering winter, an organic fertilizer can be applied, mainly decomposed cake fertilizer, and concentrated fertilizer should not be used. Fertilization should follow the principle of "frequent application of thin fertilizer," mainly using fast-acting nitrogen fertilizer and fertilizing according to the growth of the osmanthus. For newly planted osmanthus, avoid early topdressing to prevent root damage.
4. Osmanthus trees prefer to grow in warm environments, with an average temperature of 14-28°C. The temperature in winter should not be lower than 8°C, and the humidity throughout the year is best maintained between 75%-85%.
5. Osmanthus trees should be moved indoors in winter and placed in a sunny location to receive sunlight. In the summer, when the sun is strong, shading should be provided. During the growing period, ensure sufficient sunlight to avoid bud differentiation.
6. The main diseases of osmanthus trees include brown spot and withered spot diseases. A 1:2:200 dilution of Bordeaux mixture can be used for spraying. It is necessary to clear the diseased leaves and remove them in time.
7. Prune the osmanthus trees in time, cutting off the diseased branches, withered branches, and overly long branches.
The above is the specific content of how to cultivate osmanthus trees for high survival rates and the planting methods and precautions of osmanthus trees, for everyone's reference and operation.
