How to cultivate potted osmanthus
Do you know these? Here is an introduction to the green plant flowers about how to cultivate potted osmanthus and the methods and precautions for growing osmanthus in pots, with specific details as follows:
Osmanthus is one of the top ten famous traditional Chinese flowers, combining greening, beautification, and fragrance into an excellent ornamental and practical garden species. Osmanthus is clean and dust-free, with a strong fragrance that can spread far and wide, making it a unique plant. It belongs to the Osmanthus genus of the Oleaceae family, a evergreen shrub or small tree that has been loved by Chinese people since ancient times and is considered a traditional famous flower. It is widely planted in the courtyards of families, parks, and streets in southern regions. In August every year, the fragrance of osmanthus fills the air, deeply loved by people. Osmanthus is a very popular flowering plant among Chinese people. It can be cultivated in courtyards in the areas south of the Huai River, but in the North China region, potted osmanthus is generally used. How to care for potted osmanthus?
1. Cultivation time, osmanthus is usually planted in autumn or spring before germination.
2. Preparation of potting soil, planting osmanthus in a pot has many limitations. A pot is a special small environment. No matter which type of soil is used alone, it cannot meet the needs of potted flowers for all aspects of the soil. Therefore, potted osmanthus must be manually prepared to replace the soil and keep the flowers fixed in the pot, with certain water retention and drainage properties, requiring loose, fertile, well-drained, and well-ventilated soil rich in humus and not too alkaline. The potting soil for growing osmanthus usually consists of three parts garden soil, two parts coal ash or coarse sand, and one part deciduous leaf soil or household waste. Or 75% humus soil or garden soil, 25% coal ash and coarse sand.
3. The pot used for growing potted osmanthus should be relatively large, with the size of the pot matching the diameter of the osmanthus plant's crown. Generally, a two-year-old plant chooses a pot with a diameter of 20-25 centimeters, and a three-year-old seedling chooses a pot with a diameter of more than 30 centimeters. A small pot cannot meet the plant's nutrient and water needs.
4. Planting, place pebbles or coarse sand at the bottom of the pot to aid drainage, then fill in the potting soil, place the osmanthus plant in the center of the pot upright, with the roots spread out, and press the soil layer by layer when adding soil. When the soil is half full, gently shake the osmanthus plant to compact the potting soil. Do not plant too deep, and the potting soil should be 2-4 centimeters away from the pot opening. After potting, water thoroughly. After potting, place the planted osmanthus in a ventilated and cool place to care for about 10 days, then manage it according to the daily method after the osmanthus has recovered.
5. Water and fertilizer management, after the osmanthus has produced new leaves, move it to a ventilated and sunny place, keep the potting soil slightly moist, and water the plant when the soil is dry, avoiding excessive watering and waterlogging in the pot. In the hot summer, when the soil is dry, increase the frequency of watering appropriately. Do not water too much during the flowering period to avoid flower drop. In winter, control watering to avoid leaf drop and affect flowering the following year. Remove accumulated water in the pot after rainfall. During the vigorous growth period, apply a thin solution of animal manure every 7 days. Apply phosphorus and potassium fertilizers from June to August before flowering. After flowering, apply dried pig manure, about one or two taels per pot. It is best to change the soil every year and repot every 2-3 years.
6. Pruning of osmanthus, the shaping and pruning of osmanthus are usually done in early spring. After the flowers fade each year, prune the dense inner branches, slender branches, diseased and pest branches, and dead branches to ensure good ventilation and light penetration. Pay attention to controlling the strong top and weak bottom, achieving a balanced tree crown, but do not prune too much, gradually training it.
7. Winter management, osmanthus that needs to be brought indoors after winter should maintain a room temperature of 0-5 degrees Celsius. High temperatures are not conducive to flowering, and humidity should be kept between 50-80%.
8. Caution, osmanthus is not resistant to soot. It often grows poorly in places with a lot of soot, with smaller leaves that easily fall off and fewer flowers.
