So, how to cultivate osmanthus? What are the issues to pay attention to in cultivation? Perhaps not everyone is very clear about this. Today, let's share some knowledge about cultivating osmanthus.
1. Selection of cultivation soil. Osmanthus prefers a warm and humid growing environment. The selected soil should be fertile, loose, and slightly acidic, with good drainage and breathability. It is best to avoid soils with high clay content and high alkalinity. For home pot cultivation of osmanthus, 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 choose a clay or ceramic pot with a diameter of 20-30 centimeters and a depth of 35-40 centimeters for planting.
2. Requirements for light and temperature. The optimal growing temperature for osmanthus is around 18-28 degrees Celsius. It is not cold-resistant, and in northern regions, measures must be taken to protect it from frost in winter, otherwise, the leaves may freeze and affect the growth of the following year. Osmanthus enjoys sunlight but can also grow well in semi-shaded conditions. It is essential to avoid direct sunlight, especially during the strong midday sun in summer, when proper shading is required.
3. How to water and fertilize. Osmanthus enjoys moisture but dislikes waterlogging. Watering should be done when the surface of the potting soil is dry, and only when the soil 2 centimeters below the surface is slightly damp. However, avoid water accumulation in the pot. During the growing period, the soil should be kept moist, and you can often spray water on the leaves, but water less during the blooming period. Osmanthus enjoys fertilizer and should be fertilized every 7-10 days during the growing period with a thin fertilizer, mainly nitrogen-based, and a phosphorus-potassium fertilizer once in summer to promote abundant flowers and lush leaves.
4. How to prune osmanthus branches. Pruning the branches of osmanthus to reduce their density can save a lot of nutrients and promote the healthy growth of the remaining branches. However, it is important to note that excessive pruning during flowering can damage the vitality of the plant and affect the blooming in the following year.
5. How to prevent and control diseases and pests. Osmanthus is prone to leaf spot disease, leaf blight, and soot disease, which can cause premature leaf drop and weaken the plant's nutritional supply during growth, thus reducing its ornamental value. For home potted osmanthus, it is important to remove diseased leaves promptly, improve ventilation and lighting, and reduce leaf moisture to prevent the spread of diseases. In the early stages of the disease, a fungicide such as carbendazim can be used at a ratio of 1:800 to spray. For pest infestations like red spiders, mitaclear can be used for foliar spraying, with both sides of the leaves sprayed 2-3 times to completely eliminate the pests.
6. How to propagate osmanthus. Osmanthus propagation by cuttings can be done before spring germination, selecting one-year-old healthy branches, cutting them into 5-10 centimeters in length, removing the lower leaves, and retaining 2-3 green leaves at the top, then inserting them into a culture medium that can be river sand, coconut bran, or vermiculite. Before inserting, moisten the culture medium and then proceed with the insertion. After inserting, seal the pot opening with plastic wrap, keep the medium slightly moist, place it in a shaded area for maintenance, and always ensure the environmental temperature is around 20-25 degrees Celsius. About two months later, you can transplant them with soil clumps into your preferred pots.
