How Many Times Does Chrysanthemum Bloom in a Year
As the main star of the autumn courtyard, chrysanthemum is deeply loved by gardening enthusiasts for its abundant flower quantity and long ornamental period. These clustering blooming chrysanthemums are not annual flowering plants, and only by mastering their unique growth patterns and maintenance points can this autumn beauty be expected year after year.
Annual Growth Cycle of Chrysanthemum
Single Season Flowering Characteristics
Chrysanthemum blooms only in autumn (August to October) each year, with a single plant capable of blooming hundreds of double flowers at the same time. Its blooming period is regulated by the photoperiod, and short-day conditions stimulate the differentiation of flower buds, so areas in the north usually enter the full blooming stage 2-3 weeks earlier than those in the south.
Advantages of Perennial Rhizome
As a rhizomatous plant, the underground stems of chrysanthemum can survive for 3-5 years. After the aerial parts wither in winter, new buds will sprout from the base the following spring, and continuous reblooming can be achieved with proper care.
Management Plan to Extend the Blooming Period
Care During Flower Bud Formation Stage
During the flower bud formation stage in July-August, ensure 6 hours of direct sunlight daily and fertilize with phosphorus-potassium fertilizer (diluted 1000 times) every 10 days. Keep the soil slightly moist without waterlogging and control the air humidity between 50-60%.
Techniques for Controlling Full Bloom Stage
Removing the central flower bud in the early stage of blooming can promote the development of side flowers, and regularly removing withered flowers can extend the overall blooming period by about 15 days. When the nighttime temperature is below 10°C, it is recommended to build a simple greenhouse to maintain the growth temperature.
Key Measures for Revitalization After Flowering
Scientific Pruning Plan
After the flowers fade, retain the main stem 15 cm from the base and make a 45° oblique cut to promote wound healing. After pruning, spray a carbendazim solution (1:800) to prevent diseases and retain 4-5 functional leaves for photosynthesis.
Timing for Potting Revitalization
Change the pot around Qingming Festival the following year, choosing a ceramic pot 5 cm larger than the original one. Mix garden soil, decomposed leaf soil, and perlite (5:3:2) and add bone meal as a base fertilizer. Place the plant in a diffused light environment for 10 days after potting to acclimate.
By accurately grasping the phenological characteristics of chrysanthemum and combining scientific maintenance methods, not only can the annual autumn bloom be guaranteed, but the plant can also maintain vigorous vitality. This cluster of autumn chrysanthemums, symbolizing noble character, will continue to add elegant charm to the courtyard under careful care.
