Follow the editor to find out more!The lotus, known as the "goddess of water," is an aquatic plant with high ornamental value. Its unique feature is that it blooms during the day and closes at night. This miraculous phenomenon of life has sparked great interest among people. This article will explore why lotus flowers open during the day and close at night and introduce how to properly care for them.I. Why do lotus flowers open during the day and close at night?This characteristic of the lotus is mainly related to the photoperiod and physiological rhythms. The lotus is a plant with very strong photosynthesis, opening during the day to fully absorb sunlight for photosynthesis and store energy. Closing at night can reduce water evaporation and prevent damage from cold dew, protecting the flowers from harm.Photoperiod: The lotus is very sensitive to light, and changes in the photoperiod will affect its growth, development, and blooming and closing. When the duration of sunlight reaches a certain threshold, the lotus will trigger its growth switch and reveal beautiful flowers; when there is insufficient sunlight, the lotus will automatically close and enter a dormant state. Physiological rhythm: The opening and closing of the lotus are also controlled by intrinsic physiological rhythms. The lotus contains a genetic mechanism called a "biological clock" that can accurately regulate the timing of flowering and closing.II. How to properly care for lotus flowers?To ensure that the lotus grows vigorously and blooms continuously, proper care is crucial. Here are some suggestions:Light: The lotus enjoys plenty of sunlight and should be placed in a well-lit area but avoiding direct sunlight. If there is insufficient light, a plant growth lamp can be used to supplement the light. Water quality: The lotus has high requirements for water quality and should use clear, unpolluted freshwater. During the growing period, it is important to observe the water quality and change it if pollution is detected. Water temperature: The suitable water temperature for lotus growth is between 20-30℃. In winter, when temperatures are lower, it is important to keep the water warm to prevent frostbite. Fertilization: The lotus grows vigorously and requires sufficient nutrients. During the growing season, a water-soluble compound fertilizer can be applied once a month, following the principle of "small amounts multiple times." Pruning: The leaves and flowers of the lotus will age as they grow and need to be pruned regularly. Removing withered leaves and wilted flowers helps maintain the plant's growth vitality. Pest and disease control: The lotus is susceptible to pests and diseases and should be inspected regularly. If pests or diseases are found, they should be treated promptly. Biological or low-toxic agents can be used for prevention and control. Overwintering: In areas with lower temperatures, the lotus needs to take measures to overwinter. It can be dug up and placed in moist sand, then stored in a basement or greenhouse.In summary, the lotus is a beautiful and unique aquatic plant. Understanding its growing habits and caring for it properly can make the lotus bloom beautiful flowers. I hope this introduction is helpful to you.
