When do chrysanthemums bloom?
This article provides an overview of the blooming month of chrysanthemums and related experience in planting methods and precautions. Let's take a look together.
Chrysanthemum, as one of the top ten traditional famous flowers in China, is known for its unique ornamental and medicinal value. The blooming period of chrysanthemums is generally in autumn, especially from September to November. Different varieties of chrysanthemums may have slightly different blooming times, but most varieties bloom during this period. The following are the planting methods and precautions for chrysanthemums:
### 1. Choose the right variety. There are many varieties of chrysanthemums, some for viewing and some for medicinal purposes. When planting chrysanthemums, it is first necessary to clarify the purpose of planting and then choose the appropriate variety according to the purpose. Ornamental varieties include multiple chrysanthemums, marigolds, and pot marigolds, while medicinal varieties mainly include Hangbaiju and Gongju.
### 2. Prepare suitable soil. Chrysanthemums prefer loose, fertile, and well-drained soil. Before planting, it is necessary to improve the soil by increasing the organic matter content and enhancing the soil's water retention and breathability. Organic fertilizers such as compost and cow dung can be added to the soil to provide the nutrients needed for the growth of chrysanthemums.
### 3. Sow at the right time. The sowing time for chrysanthemums is generally in spring, with specific times varying by region and variety. Generally, when the spring temperature stabilizes at above 15°C, sowing can begin. Before sowing, the seeds need to be soaked in water for 24 hours to promote water absorption and swelling, which can improve the germination rate.
### 4. Plant with proper density. The planting density of chrysanthemums varies by variety and purpose. The planting density of ornamental chrysanthemums is generally 30-40 cm per plant, while that of medicinal chrysanthemums is 20-30 cm per plant. When planting, dig holes according to the predetermined density, place the seeds or seedlings in the holes, cover with soil, and press firmly.
### 5. Watering and fertilizing. Chrysanthemums prefer a moist environment but are not tolerant to waterlogging. During the planting process, it is necessary to water according to soil moisture and weather conditions to keep the soil moist but not waterlogged. During the growth of chrysanthemums, it is necessary to fertilize regularly to provide ample nutrients. A combination of organic and chemical fertilizers can be used, such as applying ripe organic fertilizer every half month and a compound fertilizer every month.
### 6. Pest and disease control. Chrysanthemums may be affected by pests and diseases such as aphids, red spiders, and powdery mildew during growth. In the early stages of pest and disease occurrence, physical and biological control methods can be used, such as manually capturing pests and using natural enemies. When pests and diseases are severe, chemical control is needed, but it is important to use medications rationally to avoid harm to the environment and human health.
### 7. Pruning and shaping. Proper pruning and shaping are required during the growth of chrysanthemums to promote ventilation and light penetration, as well as to enhance ornamental and medicinal value. In the early stages of growth, weak and dense branches can be cut to promote strong plant growth. Before the flowers bloom, pinching can be performed to promote the development of lateral branches and increase the number of flowers. After flowering, withered flowers should be promptly removed to reduce nutrient consumption and promote plant recovery.
### 8. Harvesting and storing. The harvest time for medicinal chrysanthemums is generally during the bud stage, when the petals have not fully opened. When harvesting, the buds should be cut with scissors without damaging the plant. After harvesting, chrysanthemums should be dried or dried in a timely manner to maintain their medicinal value. During storage, chrysanthemums should be placed in a dry, well-ventilated, and light-avoiding environment to prevent moisture and mildew.
### 9. Winter protection. In winter, chrysanthemums require proper protection to avoid the effects of low temperatures and frost. Before frost arrives, a layer of straw or plastic film can be covered on the chrysanthemum plants to increase insulation. In winter, watering should be reduced to avoid soil freezing. In spring, when temperatures rise, the covering material can be gradually removed to allow chrysanthemums to receive sunlight and rainwater.
In summary, the planting of chrysanthemums needs to consider many aspects, including variety selection, soil preparation, sowing time, planting density, watering and fertilizing, pest and disease control, pruning and shaping, harvesting and storage, and winter protection. Only by doing a good job in these aspects can the healthy growth and high yield and quality of chrysanthemums be ensured. At the same time, the planting of chrysanthemums also needs to be adjusted and optimized according to local climate, soil, and environmental conditions to achieve the best planting results.
