What season are dandelions in?
In the warm spring sun and the midsummer breeze, dandelion becomes a poetic ornament in the fields with its unique pompool-shaped flowers. This tenacious plant not only carries childhood memories, but is also favored by gardening enthusiasts for its ornamental and ecological value. Natural rules for dandelion flowering. Regional climate affects the flowering cycle. The flowering period of dandelion shows significant regional differences. The first blooming buds can be seen in late March in the area south of the Yangtze River, the North China Plain is concentrated in May to July, and the northeastern alpine areas are postponed to June. Mid-to-August. The flowering period lasts for about 45-60 days, and a single plant can bloom 3-4 times. Double control mechanism of temperature and light is the best flowering range with the average daily temperature of 15-25℃. When the temperature exceeds 30℃, the plant enters a semi-dormant state. Scattered light energy for more than 6 hours a day promotes flower bud differentiation, but a sunshade net is needed to filter 40% of the strong light at noon in midsummer. Efficient cultivation management plan Scientific light control implements full sunshine maintenance in late spring and early summer, and cooperates with rotating flowerpots to ensure uniform light reception. When the flower stem grows to 15cm, the flowering quality can be improved by extending the light to 14 h/d. Accurate water management adopts the irrigation method of "seeing dry and seeing wet," watering water after the surface soil is dried for 2cm. It is recommended that the air humidity at flowering stage be maintained at 50-65%, and local humidity control can be achieved by tray water storage method. Nutrient supply strategy: potassium dihydrogen phosphate solution (0.2%) was applied every 15 days in budding stage, and decomposed sheep manure was used to improve soil structure. Calcium and magnesium foliar fertilizer can effectively prolong the flowering period of single flower by 3-5 days. Dandelion has multiple ornamental values. Dandelion is a seasonal morphological aesthetic feature. The full-cycle change from golden petals to silver-white pomodies is very ornamental. The compound inflorescences with a diameter of 1-3cm present dynamic beauty in the breeze, especially suitable as macro photography subjects.
