Chrysanthemum is one of the traditional horticultural plants in China. Because of its arrogant image and elegant and noble character, it is endowed with rich cultural connotation and emotional value. But how long is the chrysanthemum's growth cycle? This is a question many people want to know. This paper will introduce the growth process and cycle of chrysanthemum in detail from the beginning of seed germination.

1: The seed germination period is in spring. When the temperature gradually increases to about 10℃, the chrysanthemum seeds begin to germinate. This process takes 3-5 days. The hard shell on the outer layer of the seed is softened by water, and then the germ begins to grow and break out of the soil.
2: Seedling stage It takes about 1 week from seed germination to seedling stage. During this period, seedlings need enough sunshine, water and nutrients to grow healthily. At this time, the root system of the seedling is constantly developing and the stem becomes thicker and thicker.

3: Growing Period It takes about 2 weeks from seedling stage to growing stage. During this period, the growth rate of chrysanthemums reached its fastest. The stems and leaves continue to grow, and the buds gradually form flower buds. At this time, chrysanthemums need more nutrients and light.
Four: The flower bud stage takes about 1 week from the growth stage to the flower bud stage. During this period, the flower buds of chrysanthemums gradually become larger and their shapes begin to mature. At this time, attention should be paid to properly control the watering amount and light time to ensure that the flower buds can fully open.
Five: The flowering period takes about 1 week from the bud stage to the flowering stage. During this period, the buds of chrysanthemums gradually turn bright yellow or white. At this time, chrysanthemums need enough sunshine and appropriate temperature to stay healthy.

6: It takes about 1-2 weeks to reach full flowering stage from flowering stage to full flowering stage. During this period, chrysanthemums are at their most beautiful moment, with bright flowers and beautiful shapes. At this time, attention should be paid to timely watering and fertilizing to ensure the vitality and beauty of the flowers.
Seven: Withering period It takes about 1-2 weeks from full bloom to withering period. During this period, the flowers of chrysanthemums gradually withered and their vitality gradually weakened. At this time, watering and light time should be appropriately reduced to avoid affecting the health of the plants.
Eight: Dormitory period It takes about 2-3 months from the withering period to the dormancy period. During this period, the chrysanthemum plants entered a dormant state and the growth rate slowed down significantly. At this time, attention should be paid to properly control the temperature and watering amount to ensure the vitality of the plant.
Nine: The germination period is in spring. When the temperature gradually increases to around 10℃, the chrysanthemum seeds begin to germinate. This process takes 3-5 days. During the germination period, the chrysanthemum plants begin to recover and gradually resume growth.
Ten: The plastic surgery period takes about 1 week from the germination period to the plastic surgery period. During this period, the chrysanthemum plants need to be properly trimmed and shaped to maintain a neat and beautiful shape. At this time, pay attention to maintaining appropriate temperature and humidity.
Eleven: The update period takes about 2 weeks from the shaping period to the update period. During this period, chrysanthemum plants need to be renewed with soil and fertilizer to ensure sufficient nutrients. At this time, attention should be paid to removing pests and diseases in a timely manner to ensure the health of the plants.
Twelve: Aging period takes about 3-4 months from renewal period to aging period. During this period, the chrysanthemum plants gradually age and their vitality gradually weaken. At this time, the watering amount and light time should be properly controlled to avoid affecting the health of the plants.
Thirteen: The withering period takes about 1-2 weeks from the aging period to the withering period. During this period, the chrysanthemum plants gradually withered and their vitality was exhausted. At this time, the plants should be removed in time and garbage disposal should be carried out.
Fourteen: The regeneration period is the next spring. When the temperature gradually increases to around 10℃, new chrysanthemum seeds begin to germinate. This marks the beginning of the regeneration period of chrysanthemum. During this period, we need to start planting and caring for chrysanthemums again to ensure the continuity of the chrysanthemum growth cycle.
Fifteen: The growth cycle of chrysanthemum is a cyclical process. From seed germination to flowering to wilting, each stage requires different light, temperature and moisture to ensure the health and growth of the plant. Understanding the growth cycle of chrysanthemums can better care and manage chrysanthemums and allow them to play a better value in the horticultural landscape.
