How to Plant and Cultivate Osmanthus Trees
Today, we will introduce how to plant and properly care for osmanthus trees, sharing knowledge about the cultivation of these plants. Let's take a look together.
Osmanthus is also known as rock osmanthus. It is one of the top ten famous traditional flowers in China, combining greening, beautification, and fragrance into an ornamental garden species. The flowers of osmanthus are refreshingly dust-free when in bloom and their fragrance can spread far and wide, widely loved by everyone.
Methods for Planting Osmanthus Trees:
1. Choosing the right soil is the first and most important step in planting. Osmanthus trees require slightly acidic soil and dislike alkaline soil. For potted osmanthus, you can use sandy soil that is deep, loose, and fertile with good drainage. Use a mixture of decomposed leaf soil, garden soil, sandy soil, and well-rotted cake fertilizer in the ratio of 2:3:3:2, mix well, and then plant in the pot.
2. newly planted osmanthus trees must be watered to maintain air humidity, but they are not tolerant to waterlogging, so avoid积水. In northern winters, 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, you can apply a phosphorus and potassium fertilizer to the osmanthus tree, which is beneficial for flower and leaf growth. In winter, apply an organic fertilizer, mainly well-rotted cake fertilizer, and avoid using concentrated fertilizers. Fertilizing should follow the principle of "frequent application of thin fertilizer," mainly using fast-acting nitrogen fertilizer and adjusting according to the growth of the osmanthus. For newly planted osmanthus, avoid early top-dressing to prevent root damage.
4. Osmanthus trees prefer to grow in warm environments, with an average temperature of 14-28°C. The temperature should not drop below 8°C in winter, and the annual humidity should ideally be maintained between 75%-85%.
5. In winter, osmanthus trees should be moved indoors and placed in a sunny location to receive sunlight. In the summer, when the sun is strong, they should be shaded, ensuring they get sufficient sunlight during the growing period to avoid bud differentiation.
6. The main diseases affecting osmanthus trees are brown spot and leaf blight. You can use a 1:2:200 dilution of Bordeaux mixture to spray on the trees. It is important to promptly clear away diseased leaves and remove them.
7. Regularly prune the osmanthus tree, cutting away diseased, dead, or overly long branches.
