The key to raising good autumn chrysanthemums is to make Qiuju better than winter. The main methods for overwintering the potted autumn chrysanthemum are described as follows: Perennial root preservation method: cut the old wood after flower shearing, and then pour water once, place it in a cold room with light, and room temperature is 0°C～3°C. At this point we must strictly control the watering, do not water the basin soil too dry. When watering, the amount of water should not be less, so long as the pottings are kept wet. This will enable it to be in a fully dormant state, which is conducive to the healthy growth of Qiu Ju in the coming year. The place to be placed in winter should not be too shady. The room temperature should not be too high. Otherwise, the lack of light, excessive temperature, and excessive watering will easily lead to yellow and weak root buds. This will consume a lot of nutrients, and will inevitably affect the coming year. Normal growth and flowering. Therefore, it is necessary to maintain an environment that is not dry, wet, hot or cold throughout the winter. At the same time, care must be taken to prevent it from drying out. After the warmer weather in March of the following year, gradually increase the amount of watering, and move to the outdoor sunny place to maintain the sprouting of old roots for cuttings. Bud method: In the late fall and early winter, the first generation shoots of the rhizomes were picked. When picking buds, select buds with budding heads, dig out the soil with a sharp knife about 2 centimeters deep into the soil, and insert them into the pots and bowls containing half of the soil and fine sand. After plugging in the cold room with light, the room temperature is maintained at about 3°C, less watering, so that the basin soil remains slightly wet. Pay attention to when there are four bogey buds, avoid bogey temperature, avoid moisture, avoid bogus, avoid drying. In the middle of March of the following year, it is moved to the outside, and the leeward sunshine is exercised for 7 to 10 days. China Agricultural Network Editor
