Sweet-scented osmanthus, hi dry, evergreen seasons. With proper management, the bonsai landscape of the laurel can be flourished, and the flower blooms year after year. First, change pots and basins are generally used when the plants are 50 cm high, with 24 cm diameter flower pots; when the plants are 80 cm, 32 cm diameter flower pots are used. When changing to a large flower pot, it can be changed every 3-5 years. Prepare nutrient soil before changing basins, nutrient soil use humus soil, garden soil half mixed and stand by. When changing the basin, keep 40% of the old soil, cut off the rot, trim the old roots around the soil, and a small amount of coiled fibrous roots. After changing the basin, add a suitable amount of new soil and pour enough water. After putting it in the cool place for 10 days, move it to a sunny, well ventilated balcony or courtyard. Change basins should be selected in early March. Second, fertilizer and water management Potted osmanthus Due to the limited volume of flower pots, easy to lack nutrients, lack of water, so need to be supplemented by fertilization, watering. The topdressing should be carried out during the growing season. In the year of changing basins, from June, combine watering every 20 days or so, applying 15% of composted manure and soaked fertilizer with tung, or 15% of gluten Compound fertilizer soaked liquid fertilizer, stop fertilizer in early October. In the following year, when the plants were planted with new leaves, the above-mentioned liquid fertilizer was poured 15% every 15 days from April, and the liquid fertilizer concentration increased from 20% to 30% in June-August. If the growth is robust, reduce the number of fertilization and reduce the concentration of fertilizer solution; apply 15% of the above liquid fertilizer every 20 days from September to October, and stop fertilizing after frost. After each fertilization, depending on the dryness of the basin soil, timely watering, watering times, according to the climate, growth conditions, flexible, basin soil moisture to maintain a semi-dry state is appropriate. It is usually poured 2-4 days in spring and autumn and once in 1-3 days in summer. Clear weather, dry, pay attention to more pouring, cloudy, rainy days to less or not pouring. Osmanthus bogey wet, should not be trapped in the pot, especially in the autumn flowering season, too wet can cause falling flowers. Third, pruning pruning is mainly winter shearing, which takes place every year in the early spring. During the first winter cut, according to the seedling size, height, plant shape, etc., the main stem was short cut 1/4-1/3, prompting the adventitious buds to germinate new shoots and trimmed the dense shoots appropriately. After the trimming, the first trimmed off the dead branches, thin branches and branches, and then left 3-5 branches with short internodes, moderate open angles, and uniform spatial distribution. The rest of the buds were removed. When pruning the following year, after the prosperous lateral branches are kept, branches of the base are left as flowering branches, and then the prosperous section is cut short to allow it to grow in coordination with other lateral branches, and at the same time cut off the buds and branches that grow in the summer and autumn and control as needed. The height of the plant is combined with topping and the lower shoots are suspended to form a good canopy structure. IV. Pest control Osmanthus twigs have greyish white dots, which can be removed with a brush, or sprayed with Leko EC 1500-2000 times, once every 7 days, and even sprayed three times.
