Osmanthus is a very famous flower, and the golden autumn October is the time when osmanthus flowers are in full bloom. The refreshing fragrance is loved by many people, so everyone has started to grow osmanthus. Some friends reflect that this kind of flower does not bloom much and the fragrance is very faint. Actually, these are all related to the breeding methods. Today, I will teach you how to grow osmanthus better to make it bloom more beautiful flowers.
1. Soil Selection
Osmanthus trees prefer fertile and deep soil, it is best to use loose and breathable slightly acidic loam to avoid yellow leaves and root rot. You can mix decomposed leaf soil, garden soil, and vermiculite to make soil for planting. This kind of soil is rich in nutrients, has good breathability and drainage, and can meet the growth needs of osmanthus.
2. Temperature
Osmanthus trees are not cold-resistant and thrive in temperatures between 18-28 degrees Celsius. Growth will stop when the temperature exceeds 30 degrees. In summer, shading and care are needed, and some water mist should be sprayed around the plants to cool down; in winter, anti-freezing measures should be taken to maintain temperatures above 10 degrees to prevent frost damage that could affect the following year's growth.
3. Ensuring Sufficient Light
Osmanthus is a heat-resistant and sun-loving flower. As a long-day plant, it needs to receive sufficient sunlight every day to meet its growth needs and carry out good photosynthesis. You can place the osmanthus tree on a sunny balcony, and in summer, you can also place it outdoors to avoid long-term shading that could lead to weak branches and affect the growth and differentiation of flower buds.
4. Reasonable Watering
Correct watering methods are essential for the healthy growth of osmanthus trees. When watering osmanthus, remember the principle of "not watering when it's not dry, and watering thoroughly when you do." Keep the soil slightly moist. If you water too much, root rot may occur. If it's the rainy season, reduce watering, and during dry weather, you can spray some water on the osmanthus to increase humidity.
5. Scientific Fertilization
The amount of osmanthus flowers is directly proportional to fertilization. It is necessary to provide sufficient fertilizer for osmanthus trees, especially during the growing period. Remember the method of "applying thin fertilizer frequently." Apply a light fertilizer to the osmanthus every two weeks to promote branch growth and make the leaves more lush. By May, switch to fertilizing every 10 days.
6. Diseases and Pests
Common diseases of osmanthus include leaf spot, leaf blight, and sootycrust disease, which can cause the leaves to turn yellow and fall off, affecting their ornamental value. When diseases occur, timely pruning of diseased leaves, improving ventilation and lighting, and preventing disease infection in healthy branches are necessary. After pruning, spray with a 800-fold solution of carbendazim for disinfection. For pests such as red spiders and whiteflies, you can spray the leaf surface with acethrin.
