When do orchids bloom in what season?
As a representative of elegant flowers, orchids always show their beauty at specific seasons. There are more than 28,000 orchid families, and their flowering periods are like nature's precise clock. Different varieties correspond to unique blooming moments. Mastering the rules of opening orchids can not only improve the viewing experience, but also provide necessary cultivation knowledge for orchid farmers. The flowering period of the orchid family The cold fragrance that blooms in winter and spring From the end of the year to early spring (December to February), the black orchid adorns the cold winter with deep purple petals; the cold orchid reveals its elegant flower appearance from November to January of the following year. These cold-resistant varieties require a temperature difference of 5-15 ° C between day and night to stimulate flower bud differentiation, and northern regions need to pay attention to heat preservation at night. At the beginning of March, the main spring flowering group, Hydra is the first to flower, and the clusters can last until mid-April. The cymbidium opens from March to May, and its thick stems can carry more than 20 flowers. As the messenger of early spring, Chunlan blooms from January to March with an elegant fragrance. Jianlan, a sustainable flower species in summer and autumn, has become the main ornamental character from May to October due to its long flowering period. Reasonable temperature control (22-28℃) can make the number of blooming times per year reach 3-4 rounds. Combined with phosphorus and potassium fertilizers, it can effectively extend the flowering period of a single flower to 45 days. The core maintenance techniques and temperature control points throughout the year use a mixed substrate of pine bark + volcanic stone + lime soil (ratio 4:3:3) to ensure that the porosity is greater than 35%. Temperature management follows the principle of "no warmth in winter, no boredom in summer," and uses intelligent temperature control equipment to maintain the ideal range of 18-30℃. Collaborative management of water and fertilizer implements the watering method of "seeing dry, seeing wet", and adjusts the frequency in combination with light intensity: 3-4 days per time in spring and autumn, once in morning and evening in summer, and 7-10 days per time in winter. Use special slow-release fertilizer for orchids, combined with foliar spraying of potassium dihydrogen phosphate (concentration 0.1%), and apply additional flower-promoting fertilizer 30 days before flowering.
Orchids bloom is the perfect combination of natural rhythm and artificial maintenance. By observing the biological clock characteristics of different varieties and cooperating with precise environmental control, the cultivation vision of "orchid fragrance all year round" can be fully realized. It is recommended to establish a flowering period observation log to record correlated data between temperature, light and flowering, and gradually form a personalized maintenance plan.
