Osmanthus is a very famous flower, and the golden autumn October is the peak blooming season. The refreshing fragrance is loved by many people, so everyone starts to cultivate osmanthus. Some friends report that this flower does not bloom much and the fragrance is very faint, which is actually related to the cultivation methods. Today, we will teach you how to cultivate osmanthus better to make it bloom more beautiful flowers.
1. Soil Selection
Osmanthus prefers fertile and deep soil, ideally using loose and breathable slightly acidic loam to prevent yellow leaves and root rot. A mixture of decomposed leaf soil, garden soil, and vermiculite can be used to create a suitable soil for planting, which is rich in nutrients, has good air permeability and drainage, and can meet the growth needs of osmanthus.
2. Temperature
Osmanthus is not cold-resistant and thrives in temperatures between 18 to 28 degrees Celsius. Growth will stop when temperatures exceed 30 degrees. In the summer, provide shading and spray water mist around the plant to cool down; in winter, take measures to prevent frost, keeping the temperature above 10 degrees to avoid frost damage that affects the following year's growth.
3. Ensure Sufficient Light
Osmanthus is a heat-tolerant and sun-loving flower. As a long-day plant, it requires ample sunlight every day to meet its growth needs and perform photosynthesis effectively. You can place osmanthus on a sunny balcony, and during summer, it can be placed outdoors to avoid long-term shading that leads to weak branches and affects the growth and differentiation of flower buds.
4. Reasonable Watering
Correct watering methods are crucial for the healthy growth of osmanthus. Remember the principle of "not watering when dry, and watering thoroughly when needed" to keep the soil slightly moist. Excessive watering can cause root rot. During the rainy season, reduce watering, and in dry weather, you can spray some water mist on osmanthus to increase humidity.
5. Scientific Fertilization
The amount of osmanthus flowers is directly proportional to fertilization. Provide sufficient fertilizer for osmanthus, especially during the growing season, and remember the method of "frequent application of thin fertilizer." Fertilize every two weeks to promote branch growth and make the leaves more lush. From May, fertilize every 10 days.
6. Diseases and Pests
Common diseases of osmanthus include leaf spot, leaf blight, and sootycrust disease, which can cause yellowing and leaf drop, affecting its ornamental value. When diseases occur, promptly prune the diseased leaves, improve ventilation and lighting, and prevent the spread to healthy branches. After pruning, spray a 800-fold solution of carbendazim for disinfection. For pests like red spiders and whiteflies, spray the leaves with acrinathrin.
