How to propagate osmanthus trees
This article brings you the topic of how to propagate osmanthus trees and the key points of osmanthus tree cultivation technology, please see the detailed introduction below.
Osmanthus is also known as rock osmanthus. Osmanthus is one of the top ten famous traditional flowers in China, integrating greening, beautification, and scent into an ornamental garden species. When osmanthus flowers bloom, they can be both refreshingly dust-free and strongly fragrant, widely loved by everyone.
Osmanthus tree planting methods:
1. Choosing soil is the first step in planting, and also the most important one. The soil requirements for planting osmanthus trees are slightly acidic and alkaline soil is to be avoided. Potted osmanthus can use sandy soil with a thick layer, loose and fertile, and good drainage. A mixture of decomposed leaf soil, garden soil, sand, and decomposed cake fertilizer in the ratio of 2:3:3:2 can be used to mix evenly and then planted in pots.
2. Newly planted osmanthus trees must be watered to maintain the humidity in the air, but osmanthus trees are not tolerant of waterlogging, so avoid积水. In northern winters, potted osmanthus should be kept in a well-ventilated and sunny room with less watering. After April, the water volume can be appropriately increased.
3. In the summer, osmanthus trees can be applied with a phosphorus and potassium fertilizer, which is beneficial for flowering and lush foliage. 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 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℃, and cannot be lower than 8℃ in winter. 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 light. In the summer, when the sun is strong, they should be shaded, and they should have sufficient sunlight during the growing period to avoid flower bud differentiation.
6. The main diseases of osmanthus trees include brown spot and dry spot diseases. A 1:2:200 dilution of Bordeaux mixture can be used for spraying. It is necessary to clean up diseased leaves and remove them promptly.
7. Prune osmanthus trees in time, cutting off diseased branches, withered branches, and overly long branches.
