When do chrysanthemums with multiple heads bloom?
As the main star of autumn gardens, chrysanthemums with multiple heads are deeply loved by horticulture enthusiasts for their profuse blooms. However, different varieties of chrysanthemums with multiple heads have significant differences in blooming times, ranging from early summer to the cold winter, their blossoms can be seen. Mastering the blooming patterns can not only create a seasonal flower view but can also extend the viewing period through scientific maintenance.
Chrysanthemum blooming time spectrum
Early blooming varieties from May to July
As the earliest blooming variety, Hongzao flowers with small blooms of 3-5 cm in diameter by late May. June brings the blooming peak of medium-sized varieties like Yuezao and Baidan, which are usually 40-60 cm tall and suitable for potted display. The Chunxiang series that bloom in July can reach 80 cm and require support stakes to prevent falling over.
Autumn chrysanthemums in full bloom from September to October
Classic varieties like Xue and Binzhai enter full bloom in September, with flower diameters generally reaching 8-12 cm. The Haomalao series that bloom in October are known for their double petals, with a single plant producing up to 30-50 flowers. At this time, additional phosphorus and potassium fertilizers should be applied to enhance cold resistance.
Blooming in the cold winter from November to December
Late blooming varieties like Feitisa bloom in early winter, with these plants able to tolerate temperatures as low as -5°C through low-temperature acclimatization. It is recommended to pair them with greenhouse or warm shed care, maintaining a day-night temperature difference within 8°C to effectively extend the blooming period to the following January.
Techniques to extend the blooming period of chrysanthemums with multiple heads
After blooming, promptly prune the spent flowers to retain nutrients, and apply decomposed organic fertilizer and 0.2% phosphorus acid hydrogen potassium foliar fertilizer monthly. In summer, use shading nets to control light intensity to below 30000 lux, and in winter, supplemental lighting is needed to maintain a 14-hour daily light cycle. Temperature control can extend the blooming period of a single plant by 15-20 days.
From the early bloom of Hongzao in early summer to the proud display of Feitisa in the cold winter, chrysanthemums with multiple heads string together the beauty of all four seasons with their long blooming period of up to seven months. By mastering the characteristics of different varieties and combining scientific maintenance methods, one can create a continuous feast of blooming art.
