What are the fertilizer precautions for osmanthus bonsai?
Osmanthus is very famous in China. Because osmanthus has a rich fragrance and can also be made into food ingredients, osmanthus bonsai is an ideal household potted flower. So when cultivating osmanthus, how should you fertilize osmanthus to ensure the flowering quality of osmanthus?
Osmanthus
Because potted osmanthus has limited potting soil and insufficient nutrients, it is difficult to meet the needs of long-term osmanthus growth and development, so fertilizer must be continuously supplied. Otherwise, the plant will be weak, new shoots will grow poorly, flower buds will be few, flowering will be sparse, or it may even fail to bloom, seriously affecting the ornamental effect.
After mid-October, the flowering of potted osmanthus has basically ended. At this time the temperature is still high, and the photosynthesis of osmanthus leaves is still going on; at the same time, the root growth of osmanthus has not yet stopped, and it is also entering the autumn growth peak. At this time, apply 1 quick-acting fertilizer mainly of nitrogen fertilizer, supplemented with phosphorus and potassium fertilizer, to help accumulate nutrients, strengthen the root system, and lay the foundation for the growth and flowering of potted osmanthus next year. The fertilizer should not be too concentrated, the amount should not be too much, and the timing should not be too early, to avoid triggering new autumn shoot branches.
Fertilizing potted osmanthus should use local materials, mainly farmyard organic fertilizer. Home flower growers can apply fully decomposed bean cake water or soybean water, etc. When using chemical fertilizers, you should understand the composition and content of the fertilizer, and apply it reasonably according to the different growth and development stages of potted osmanthus. The safe concentration of urea is 0.5%-1.0%, and the safe concentration of superphosphate is 2%.

Shaping: Osmanthus bonsai shaping adopts a method combining bending and pruning. The trunk can be bent into a curved-trunk form or a slanting-trunk style. If the trunk is relatively tall, it can be appropriately shortened to encourage new branches and trunks to sprout from the base, so that the lower part will not be empty, or heavily prune the upper branches and overly dense branches to stimulate new branches from the lower part of the trunk, maintain balance between top and bottom, make the tree shape beautiful, and make flowers and leaves luxuriant.
Material selection: The stump material for making osmanthus bonsai can be obtained through sowing, cuttings, layering, grafting, and division propagation to raise seedlings, or old Chinese fringetree stumps collected from the mountains and fields can be used as material for osmanthus bonsai.
Pruning: During the first pruning, according to the size, height, plant shape, and other conditions of the seedling, shorten the trunk by 1/4-1/3 to promote adventitious buds in the lower part to sprout new branches, and appropriately prune overly dense branches. After that, prune dead branches, thin and weak branches, and diseased and damaged branches, then prune year by year according to the desired plant shape, pruning leggy branches and overly dense branches, gradually forming the required tree shape.
Watering: Because osmanthus bonsai has limited pot capacity, it is prone to insufficient water, so water must be supplemented by watering. Water timely according to the dryness and moisture of the potting soil of the osmanthus bonsai. Generally, in spring and autumn, water once every 2-4 days, and in summer, water once every 1-3 days. When the weather is clear and dry, water several more times, and on cloudy and rainy days, water less or not at all. Osmanthus dislikes wetness, and water accumulation in the pot must be avoided, especially during the autumn flowering season, as excessive moisture will cause flower drop.
Fertilizing: During the growth period of osmanthus, apply once every 20 days a fertilizer liquid made by soaking 15% decomposed pig manure and tung bran, or a liquid fertilizer made by soaking 15% tung bran and compound fertilizer. Stop fertilizing in early October. The next year, after osmanthus grows new leaves, apply liquid fertilizer once every 15 days, and from June to August increase the liquid fertilizer concentration to 20%-30%. From September to October, apply the above liquid fertilizer at 15% once every 20 days, and stop fertilizing after Frost's Descent.

Osmanthus has strong sprouting ability and tolerance to pruning. One to two years after potting, during the plum rain season or after autumn flowering, process and shape it using a method combining bending and pruning. The trunk can be bent into a curved-trunk form or a slanting-trunk style; if the trunk is relatively tall, it can be appropriately shortened to encourage new branches and trunks to sprout from the base, so that the lower part will not be empty, or heavily prune the upper branches and overly dense branches to stimulate new branches from the lower part of the trunk, maintain balance between top and bottom, make the tree shape beautiful, and make flowers and leaves luxuriant. Osmanthus is best shaped into a curved-trunk style, slanting-trunk style, or flowing style. The tree posture spreads diagonally, with dense branches and leaves, simple and natural, and is most enjoyable to appreciate. When flowering, the strong fragrance fills the air and refreshes the heart.
For potted osmanthus, first choose slightly acidic soil; at the same time, water timely and grasp the principle of "two less, one more"; skillfully apply topdressing, applying once every 10 days in spring a fully decomposed dilute cake fertilizer water, after July apply dilute decomposed chicken and duck manure water or fish offal water, and in early September apply once a liquid fertilizer mainly of phosphorus fertilizer; prune appropriately.
In short, osmanthus has the flower language of nobility, beauty, auspiciousness, and friendliness, and using osmanthus bonsai as a gift for friends is a very good present.

Pot selection: Osmanthus has green leaves and yellow flowers and stays evergreen all year round. It is advisable to choose a relatively deep round pot or square pot. The diameter of the pot mouth should be roughly equivalent to the spread of the osmanthus branches and leaves, which is beneficial to root development and growth. The texture of the pot is best if it is purple clay pottery or glazed pottery. The color is better if it is purple or ochre, which can form a sharp contrast with the colors of the flowers and leaves and increase its ornamental effect.
Soil: Osmanthus likes fertilizer, so it is advisable to use fertile, loose, and well-drained sandy loam. The culture soil for potted osmanthus is usually prepared from garden soil, composted manure, and river sand in a ratio of 1B3 each. Attention must be paid to disinfection treatment so that it will not be infected by pests and diseases.
Osmanthus cultivation techniques: Osmanthus is suitable for planting in early spring or autumn. Before potting, place a layer of river sand or vermiculite at the bottom of the pot to facilitate ventilation and drainage, and then spread a layer of peat soil or fine mud about 2-3 cm thick on top, reaching 1B3 of the pot depth. Then, put the osmanthus seedling with a root soil ball into the pot, fill it with culture soil, press firmly with your fingers, and fill soil until close to the pot mouth. The soil surface should be 2-3 cm lower than the pot mouth to facilitate watering and fertilizing. After planting, water thoroughly, then move it to a shaded place for about 10 days so that it can "adapt to the pot" and gradually resume growth.
