Chrysanthemum is afraid of waterlogging, has strong drought resistance and good working ability. Therefore, in the case of watering, the water flow should be moderate and the bonsai soil should be kept moist. It is better to water less than to water more to prevent bonsai soil from storing water. In the growing season of spring and autumn, dilute liquid fertilizer should be applied to the loose-leaved chrysanthemum once every half month to ensure sufficient nutrients, so that the plants can grow vigorously and promote flowering. However, it should be noted that there should not be too much liquid fertilizer, otherwise the plants will grow steeply and bloom less. In summer and winter, because the temperature is too high or too low, it is necessary to stop fertilization and reduce irrigation.
Chrysanthemum morifolium likes warm and sunny natural environment, and the suitable temperature for its growth is between 18℃ and 25℃. It is not tolerant of low temperature and afraid of high temperature. Autumn and spring are the growing seasons of chrysanthemums, and the temperature and light are also suitable, so you should get more exposure to the sun. In summer, the sunshine is obvious and the temperature is high, so shading and maintenance must be carried out in a cool and naturally ventilated place. In winter, the temperature is low, so it should be kept in an area with obvious indoor sunshine and the temperature should be kept within a certain range.
In the whole growth process, common diseases and insect pests are brown spot, rust, budding insects and so on. We often observe the growth of chrysanthemum plants, find diseases and deal with them properly. In the early growth stage of chrysanthemum, the top can be picked to promote the growth of plants. Pruning should be done moderately after flowering to keep the plant beautiful and generous. In the whole growth process, we must pay attention to its over-summer and over-winter to prevent plant death. Chrysanthemum morifolium likes warm, dry and naturally ventilated natural environment, and the lowest temperature is 10℃. Growing season is not suitable for being too wet and too cold. Good lighting is necessary except in summer. Loose, moderately rich sandy loam and excellent drainage pipes are needed.
plant
The survival seedlings of cuttings can be planted with 3-5 plants in potted flower pots, and the pot soil is molded with sandy soil, and some fertilized peanut bran is added as base fertilizer. Because of the poor flowering of the old plants, the trees will be upgraded to cultivate new plants in 2-3 years. Fertile pine leaves and chrysanthemums like warm, dry and sunny natural environment, which is neither resistant to low temperature nor high temperature, and is afraid of waterlogging and drought. Spring and autumn are the key growth periods, and fertilization can be applied once every half month to make the plants grow vigorously and bloom continuously. But too much liquid fertilizer, especially too much base fertilizer, will lead to steep plant growth and reduced flowering. Bonsai soil should be kept moist at ordinary times, and it is better to water it less and more. In addition to a little shade in summer, we should give plenty of light in other seasons. If the light is not enough, the pitch will be lengthened, the stems and leaves will be soft, and it is very easy to drop seedlings.
When plants are semi-dormant in hot summer, they should be kept in a cool place with natural ventilation, stop fertilization and control irrigation amount to avoid root rot caused by high temperature, humidity and cold. The winter temperature cannot be lower than 10? C, stop fertilizing, reduce watering and keep the leaves from wrinkling. If the temperature is low and the environmental humidity is high, the leaves are easy to wither and relax, and even the whole tree withers and dies in severe cases. When planting, you should always pick the top of the plant to control the upward trend, promote more branches, and then achieve the purpose of more flowers. Turn over the basin once a year in early spring, and it should be planted in a place with rich sandy soil layer and excellent ventilation performance of drainage pipes. Trim plants and promote new branches when turning pots. Beautiful flowers can be given until April-May.
Cutting propagation method
Chrysanthemum fruit is not easy to be perfect, and seed collection is difficult, so cutting is often used. Autumn and spring are cutting time. Choose plump and round branches, cut off 3-4 leaves and shoots about 5 cm long as cuttings. Roots can grow up and down in 1 month when inserted into sandy loam and kept at a certain temperature and environmental humidity. When 2% red bean syrup is needed to solve the cutting problem 10 hour before cutting, the actual effect of long roots is stronger. It can also be planted and propagated in spring. Seed germination is very easy, but it is not easy to pick. The seedlings survived by cutting can be planted in an egg shell pot of 1 8cm, and the pot soil should be sandy soil, and some fertilized peanut bran should be applied as base fertilizer.
Because the old plant didn't bloom well, the tree was upgraded for 2-3 years. Applying 1 times thin fertilizer every half month can promote the growth and development of plants, and the leaves are flourishing. Irrigation should be sufficient during the growing period, and rainy weather and rainy season should be controlled. The temperature and light in the growing season, with at least 6 hours of sunshine every day, will flourish and produce bright flowers. The growth temperature is 18-25℃, and it should be kept in a cool place in summer and watered to make it semi-dormant. In winter, it should be placed in an indoor sunny area, and the indoor temperature should be kept at 5- 10℃. Plastic and cosmetic pruning 1 time at the initial growth stage. Buds should be trimmed and shaped appropriately to maintain a beautiful and generous plant shape.
