How Can Osmanthus Blossom
Here we share how to make osmanthus bloom and some small gardening knowledge about the planting steps of osmanthus. Below is a detailed introduction for you.
Osmanthus is a very famous flower, and the golden autumn, October, is the time when osmanthus is in full bloom. The refreshing fragrance is loved by many people, so everyone starts to cultivate osmanthus. Some friends have reflected that this flower does not bloom much and the fragrance is very faint, actually, all these are related to the cultivation methods. Today, I will teach you how to cultivate osmanthus better to make it bloom more beautiful flowers.
1. Soil Selection
Osmanthus prefers fertile and deep soil, and it is best to use loose and breathable slightly acidic loamy soil to avoid yellowing leaves and root rot. A mixture of decomposed leaf soil, garden soil, and vermiculite can be used to prepare the soil for planting. This type of soil is rich in nutrients, has good breathability and drainage, and can meet the growth needs of osmanthus.
2. Temperature
Osmanthus is not cold-resistant and thrives in temperatures between 18-28 degrees Celsius. Growth will stop when temperatures exceed 30 degrees. In summer, it needs to be shaded and water mist should be sprayed around the plant to cool down. In winter, measures should be taken to prevent frost, maintaining temperatures above 10 degrees to prevent frost damage that could affect the next year's growth.
3. Ensuring Sufficient Light
Osmanthus is a heat-tolerant, sun-loving flower. As a long-day plant, it needs to receive ample sunlight every day to meet its growth needs and carry out photosynthesis effectively. You can place osmanthus in a sunny balcony, and it can also be kept outdoors in the summer. Avoid keeping it in a shaded environment for long periods, as this can lead to weak branches and affect the growth and differentiation of flower buds.
4. Reasonable Watering
Proper watering is an important part of ensuring the healthy growth of osmanthus. When watering osmanthus, always remember the principle of "water only when dry, and water thoroughly when you do." Keep the soil slightly moist. Too much watering can lead to root rot. Reduce watering during the rainy season and spray some water mist on osmanthus to increase humidity when the weather is dry.
5. Scientific Fertilization
The amount of osmanthus flowers is directly proportional to fertilization. It is necessary to provide sufficient fertilizer for osmanthus, especially during the growing season. Remember the method of "applying thin fertilizer frequently." Fertilize every two weeks with a dilute fertilizer 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 yellowing and shedding of leaves, affecting its ornamental value. When diseases occur, prune the diseased leaves promptly, improve ventilation and lighting to prevent the disease from infecting healthy branches and leaves. After pruning, spray with a 1000-fold solution of carbendazim for disinfection. For pests like red spider mites and whiteflies, you can spray the leaves with pyridalyl.
