Why Can't We Keep Begonias at Home?
As a traditional famous flower in China, begonias are loved for their beautiful and艳 (gorgeous) blooms. However, there is a saying among the people that 'it is not suitable to keep begonias at home.' This misunderstanding often stems from a one-sided understanding of the characteristics of the plant. This article will combine scientific maintenance and traditional culture to uncover the real taboos and correct methods of growing begonias at home.
The Three Major Misunderstandings about Begonia Maintenance at Home
Misunderstanding 1: The Feng Shui Taboo of the Whole Plant Being Harmful
Traditional Feng Shui believes that live potted begonias are 'money-attracting plants,' with their round leaves and bright red flowers symbolizing the accumulation of wealth. What truly needs to be avoided is the dried begonia decorations, as recorded in the ancient book "Qun Fang Pu," which states that their dried state easily forms a 'sha' pattern. Modern horticultural research confirms that the volatile substances released by fresh begonias can adjust the humidity of the air, coinciding with the Feng Shui principle of 'accumulating wind and energy.'
Misunderstanding 2: Completely Unsuitable for Indoor Planting
Experimental data shows that an adult begonia plant can absorb 1.2 cubic meters of carbon dioxide per hour, and the release at night is only 0.3 cubic meters, much lower than common indoor green plants. The key is to ensure more than 4 hours of scattered light every day, and it is recommended to place it on an east-facing windowsill or with a supplementary light. Regular pruning to maintain a height of 30-50 centimeters can maintain its ornamental value and prevent excessive growth.
Misunderstanding 3: All Varieties Can Be Potted
Woody varieties such as Western Begonia and Weeping Begonia require an overwintering environment above 10 degrees Celsius. It is recommended to choose cold-tolerant varieties like the adherent begonia or the evergreen begonia. Research from the Beijing Botanical Garden in 2018 showed that mini begonia varieties can bloom all year round in a 15-25 degree Celsius environment, and using ceramsite culture can effectively prevent root rot disease.
The Four Major Advantages of Scientific Maintenance of Begonias
1. Air Purification: In addition to the regular carbon-oxygen cycle, the downy leaves of begonias can adsorb PM2.5 particles. 2. Humidity Regulation: The transpiration keeps the indoor humidity stable within the healthy range of 40-60%. 3. Emotional Healing: The pink flowers stimulate the brain to secrete 5-HT, easing anxiety. 4. Cultural Implications: The idiom 'Begonia Spring Nap' endows the space with aesthetic value.
By scientifically selecting the location and variety, begonias can become high-quality household plants. It is recommended to maintain the potting soil slightly acidic (pH 5.5-6.5), supplement with bone meal during spring and autumn, and avoid positions directly exposed to air conditioning to create a healthy and beautiful begonia home landscape.
