Osmanthus, as one of the famous traditional flowers in China, is deeply loved by people for its unique fragrance and graceful posture. Potted osmanthus, due to its easy maintenance and strong ornamental value, has become a favorite in many households and offices. To make potted osmanthus bloom more luxuriantly and fragrant, proper fertilization is the key. This article will introduce in detail how to fertilize potted osmanthus, helping you to cultivate beautiful osmanthus.
Understanding the growth habits of potted osmanthusBefore fertilizing, it is very important to understand the growth habits of potted osmanthus. Osmanthus prefers a warm and humid environment, has poor cold resistance, and is suitable for growing in fertile and well-drained soil. The flowering period of osmanthus is generally from September to October, and fertilization should follow its growth rhythm.
Fertilization time and frequency1. Spring fertilization: Spring is the vigorous growth period of osmanthus. At this time, the amount of fertilization should be appropriately increased. Generally, fertilization starts in March, with one application every 15 days until one week before flowering.
2. Summer fertilization: In summer, the temperature is high, and the growth rate of osmanthus slows down. Therefore, the frequency of fertilization should be reduced, and one application per month is sufficient.
3. Autumn fertilization: Autumn is a key period for osmanthus to form flower buds. The application of phosphorus and potassium fertilizers should be increased to promote the development of flower buds. Generally, fertilization starts in August, with one application every 20 days until flowering.
4. Winter fertilization: In winter, osmanthus enters a dormant period and basically does not require fertilization. However, one application of organic fertilizer can be applied after the leaves fall in winter, in preparation for the next year's growth.
Fertilization methods and fertilizer selection1. Fertilization methods: There are mainly two types of fertilization methods for potted osmanthus - base fertilizer and top dressing. Base fertilizer is generally applied in spring, mainly organic fertilizers such as decomposed chicken manure and cow dung, while top dressing is selected based on the growth stage with appropriate fertilizers such as nitrogen, phosphorus, and potassium.
2. Fertilizer selection: When choosing fertilizers, the following principles should be noted:
- Choose fertilizers that are non-polluting and non-harmful.
- Choose appropriate fertilizers based on the growth stage and needs of osmanthus.
- Pay attention to the fertility of the fertilizer to avoid over-fertilization.
Precautions for fertilization1. Fertilization amount: The amount of fertilization should be determined based on the size and growth condition of the potted osmanthus, avoiding over-fertilization that may cause root burn.
2. Fertilization time: Fertilization should be done in the morning or evening to avoid direct sunlight.
3. Fertilization method: When fertilizing, spread the fertilizer evenly on the surface of the potting soil and then cover it with soil to avoid direct contact between the fertilizer and the roots.
