How to plant potted osmanthus trees

1. Placement:

Potted osmanthus trees should be placed in a warm and sunny place. They should be properly shaded in summer and avoid strong light. Direct shot. In areas north of the Yangtze River, they must be kept indoors for overwintering in winter. It is safer to keep the room temperature at 0-5℃. You can leave the house around the time of the Waking of Insects in the following spring.

2. Watering:

The pot soil should be watered only if it is dry and watered thoroughly. Generally, watering should be done every 3-4 days in spring and autumn, once a day when the temperature is high in summer, and once every 7-10 days in winter. Watering should be done in the morning and evening in summer, and around noon in winter, so that the water temperature is close to the soil temperature. It will not cause sudden cold or heat to damage the root system. Water appropriately in autumn, and prevent the pot soil from getting too wet or accumulating water during the rainy season.

3. Fertilization:

Osmanthus is mainly used for viewing flowers, so sufficient fertilizer should be supplied. When the shoots are growing, nitrogen fertilizer can be applied 1-2 times to promote the growth of branches and leaves; before flower bud differentiation and flowering, phosphorus fertilizer is mainly applied. After moving the sweet-scented osmanthus to the open air in spring, start pouring the cooked and thin bean cakes. Sesame paste, fishy water, etc., once every half month, water once a week from the end of May to before flowering, gradually increase the concentration of fertilizer and water, and topdress with 0.5% potassium dihydrogen phosphate solution every half month from July to August. Apply a light fertilizer solution after flowering to avoid causing autumn branches. In winter, more organic fertilizers and phosphorus and potassium fertilizers should be applied. Generally, 25-30 grams of retting and deodorized cake fertilizer and 10-15 grams of potassium dihydrogen phosphate are applied to the roots every 15-20 days, mixed with 2-3 pounds of water. Apply after drenching, and spray 1000 times nucleotide on the leaves every 10-15 days. 600 times high-efficiency biological phosphorus and potassium fertilizer mixture, spray all branches and leaves evenly until water begins to drip. Before fertilizing, the pot soil should be slightly dry, and the soil should be loosened first to facilitate the absorption of fertilizer. Water should be watered once on the second day of fertilization. If compost or manure is used, it must be completely decomposed before use (the sign is that the fertilizer juice turns black). When applying chemical fertilizer superphosphate, its concentration cannot exceed 2%, and the urea concentration is 0.5-1.0%.

4. Invert the pot:

Potted osmanthus should be inverted and replaced with soil every 2-3 years. Cut off part of the old and dead roots, and use a bamboo skewer to remove part of the old soil. Before potting, put a layer of river sand or vermiculite on the bottom of the pot to facilitate ventilation and drainage, and place decomposed cake fertilizer on the bottom of the pot as base fertilizer. The filling soil must be compacted, which can promote the luxuriant flowers and leaves of the sweet-scented osmanthus. The soil ratio for potted hanging flowers is not very strict. It can usually be prepared with 1/3 each of garden soil, manure and river sand. If the acidity is too high, some lime powder or plant ash can be added; if the alkalinity is too strong, some aluminum sulfate or ferrous sulfate can be added. In spring, after the potted osmanthus is planted, water it thoroughly and then move it to a shaded place for about 10 days to allow it to "fit into the pot". During the potting period, no fertilizer can be applied. Water and fertilize only after growth resumes and new leaves appear. The texture of the flower pot is preferably purple sand pottery pot or glazed pottery pot, and the color is preferably purple or ocher, which can be in sharp contrast with the colors of flowers and leaves to increase its ornamental effect.

5. Pruning and shaping:

Pruning and pruning of potted osmanthus trees should be carried out after autumn. Cut off the upper branches that are too strong to balance the tree vigor. Overly dense branches should be thinned out, and diseased and weak branches should be removed to concentrate nutrients to facilitate flowering. Plastic pruning combined with water and fertilizer management can improve the robust growth of bonsai and maintain its graceful posture.
