With the growing number of flower enthusiasts, the fragrance of osmanthus travels far and wide, deeply cherished by people. More and more flower lovers are starting to cultivate osmanthus at home.
So, how to cultivate osmanthus? What are the issues to consider in its care? These may not be clear to everyone. Today, let's share some knowledge about cultivating osmanthus.
1. Selection of cultivation soil. Osmanthus prefers a warm and humid growing environment and the ideal soil should be fertile, loose, and slightly acidic, with good drainage and breathability. It dislikes soil that is sticky and alkaline. For home pot cultivation, a mixture of peat soil, garden soil, and vermiculite rich in organic matter can be used to prepare the cultivation soil. It is suitable to plant in earthenware or ceramic pots with a diameter of 20~30 centimeters and a depth of 35~40 centimeters.
2. Requirements for light and temperature. The optimal growing temperature for osmanthus is around 18~28 degrees Celsius. It is not frost-resistant, so in northern regions, it needs protection against freezing in winter, otherwise, the leaves may freeze and affect the growth the following year. Osmanthus enjoys sunlight but can also grow in semi-shaded conditions. It should be protected from direct sunlight, especially during the strong midday sun in summer.
3. How to water and fertilize. Osmanthus prefers moist conditions but dislikes waterlogging. Watering should be done when the surface of the potting soil is dry, and the soil is slightly moist 2 centimeters below the surface. Avoid积水 in the pot. The soil should be kept moist during the growing period, and the leaves can be sprayed with water frequently, but less watering is needed during the flowering period. Osmanthus enjoys fertilizer, with a thin application every 7~10 days during the growing period, mainly using nitrogen fertilizer. A phosphorus and potassium fertilizer can be applied in summer to promote abundant flowers and leaves.
4. How to prune osmanthus branches. Pruning the branches to reduce their density can save a lot of nutrients and promote the healthy growth of the remaining branches. However, care must be taken not to prune too much during flowering, as this may damage the plant's vitality and affect the next year's bloom.
5. How to prevent and treat diseases and pests. Osmanthus is prone to leaf spot, leaf blight, and sootycrust diseases, which can cause premature defoliation and weaken the plant's nutrient supply, reducing its ornamental value. For home pot cultivation, diseased leaves should be removed promptly, ventilation and light should be improved, and leaf surface moisture should be reduced to prevent the spread of diseases. In the early stages of disease, a fungicide like carbendazim can be used at a dilution of 1:800. For pests like red spiders, miticide can be sprayed on the leaves, making sure to spray both sides of the leaves, with repeated applications 2~3 times to completely eliminate the pests.
6. How to propagate osmanthus. The cutting propagation of osmanthus can be done before the spring sprouts. Choose one-year-old healthy branches, cut them into 5~10 centimeters long, remove the lower leaves, retain 2~3 green leaves at the top, and insert them into the culture medium, which can be river sand, coconut bran, or vermiculite. Wet the culture medium before planting, then seal the pot opening with plastic wrap, keep the medium slightly moist, place it in a shaded area for care, and always maintain an ambient temperature of 20~25 degrees Celsius. After about 2 months, it can be transplanted with soil to the pot of your choice.
