Cultivation methods and precautions of Osmanthus fragrans

Osmanthus fragrans is a very popular ornamental plant with a strong fragrance and blooming all year round. It is suitable for garden planting or potted maintenance. Osmanthus fragrans likes light, but needs to avoid direct sunlight in summer. The lighting time can be appropriately increased in winter. Let’s learn about the cultivation methods and precautions of Osmanthus fragrans below.

1. Breeding methods

1. Choose the right venue

Osmanthus fragrans prefers an environment with plenty of sunlight, but can also tolerate partial shade. When choosing a planting location, ensure that it receives at least 4-6 hours of sunlight per day and avoid prolonged exposure to the sun or complete shade.

2. Soil selection

Osmanthus fragrans is suitable for growing in loose, fertile, well-drained acidic soil. You can mix humus, river sand, garden soil and coal slag in a certain proportion to ensure the air permeability and fertility of the soil.

3. Watering management

Osmanthus fragrans has a moderate demand for water, and watering should follow the principle of "watering when the soil is dry and watering when the soil is wet". Keep the soil moist, but avoid waterlogging, especially in winter, when you need to water less frequently to prevent root rot.

4. Fertilization management

Osmanthus fragrans likes fertilizer and needs to be fertilized regularly during the growing period. Apply diluted cake fertilizer water or compound fertilizer once a month. During the bud formation period, additional phosphorus and potassium fertilizers can be applied to promote flower development.

5. Temperature management

Osmanthus fragrans likes a warm environment, and the most suitable growth temperature is 18℃-25℃. The temperature in winter should not be lower than 5℃, otherwise frost damage may occur.

6. Pruning and shaping

Regular pruning can promote the healthy growth and flowering of Osmanthus fragrans. After the flowering period is over, cut off dead flowers and overly dense branches in time to reduce nutrient consumption and keep the plants well ventilated and light-permeable.

7. Reproduction Method

Osmanthus fragrans can be propagated by cuttings or division. When taking cuttings, choose strong branches and insert them into moist soil. They will take root in about 2-3 months.

2. Precautions

1. Keep warm

Osmanthus fragrans is not cold-resistant, so anti-cold measures need to be taken in winter. You can cover the plant with insulation or move it to a warmer place indoors.

2. Pest and disease control

Osmanthus fragrans is easily infected by pests such as red spider mites and white scale. Check the leaves regularly and spray pesticides if any pests or diseases are found.

3. Avoid stagnant water

Osmanthus fragrans cannot tolerate waterlogging. During the rainy season, attention should be paid to drainage to avoid the roots being soaked in water for a long time.

4. Adequate lighting

Osmanthus fragrans needs plenty of sunlight, insufficient light will affect its flowering effect. Appropriate shade can be provided in summer, while sufficient sunlight must be ensured in winter.

5. Repotting and loosening the soil

Potted osmanthus fragrans needs to be repotted regularly, and the potting soil should be replaced every year or every two years. At the same time, regular loosening of the soil can prevent soil compaction and promote root growth.

In short, Osmanthus fragrans has high temperature requirements, and the indoor temperature should be kept between 15℃-25℃. Avoid placing it in poorly ventilated places such as air conditioning vents, radiators, etc. Keep the soil moist, but avoid standing water. Reduce watering frequency in winter. It can effectively improve the growth quality and flowering effect of Osmanthus fragrans.
