How does bauhinia blossom in autumn?
In the golden autumn, bauhinia blossoms brilliantly. This common ornamental tree in the south shows unique flowering characteristics in autumn. As a typical secondary flowering plant, the maintenance of bauhinia in autumn directly affects the flower quantity and ornamental effect. Mastering scientific management methods can make red flowers and green leaves look interesting. Bauhinia flowers in autumn flowering characteristics, color and shape, the Bauhinia flowers in full bloom in autumn have a gorgeous rose red color. The butterfly-shaped corolla has a diameter of 10-12 cm. It consists of 5 petals in a unique shape: the two pairs of petals at the bottom are symmetrically unfolded, and the single petal at the top is like a flag. Raise high. The germination period of new leaves overlaps with the flowering period, forming a special landscape with red leaves lining red flowers. The three major elements of autumn maintenance are all-sunshine environmental management, ensuring 6-8 hours of direct light every day, and the south-facing open environment is the most ideal. Insufficient light will reduce the number of flowers by 30%-50%. It is recommended to increase the light transmittance by thinning the inner branches so that each cluster of inflorescences can fully receive light. The intelligent water control plan adopts the "see dry, see wet" irrigation method, which is poured thoroughly after 2 cm of topsoil is dry. Keep the air humidity at 60%-70%. Spray it around the plants in the morning and evening to increase humidity to avoid direct spraying and causing mildew. It is recommended to install a soil hygrometer for accurate monitoring. The periodic fertilization strategy starts from the flower bud differentiation period, and potassium dihydrogen phosphate (concentration of 0.2%) is applied every 15 days, combined with decomposed soybean cake water to supplement organic matter. Apply more boron fertilizer in full flowering period to promote pollen vitality, and pour back water immediately after fertilization to prevent root burning. Collaborative pest and insect pest control focuses on aphids and coal pollution diseases in autumn, and sprays matrine biological preparations every month for prevention. Remove diseased leaves in time when found, keep the plants ventilated and transparent, and clean the fallen leaves on the ground every week to prevent the growth of bacteria.
Through precise light, temperature, water and fertilizer control, bauhinia can last for 40-50 days. It is recommended to establish a maintenance log to record the time of each fertilization and plant response, and gradually optimize personalized maintenance plans to keep the courtyard in autumn forever.
