Why can't I grow osmanthus at home?
Every golden autumn season, the fragrance of osmanthus always makes people fascinated. However, the statement that "osmanthus is not suitable for growing osmanthus at home" has discouraged many flower lovers. Where do these taboos originate? What issues should we pay attention to in modern home planting? Let us discuss from two dimensions: scientific conservation and traditional folk customs. 1. Folk disputes over osmanthus planting 1.1 The two sides of the feng shui theory "Yin and Yang Zhai Jing" The saying that "osmanthus in the courtyard, ghosts return outside the house" is often cited as a taboo basis, but there is also an auspicious record in ancient books that "osmanthus planted in front of the door, noble people come naturally." Folk experts pointed out that such contradictory statements reflect regional cultural differences. The north mostly regards osmanthus as a "ghost tree", while the Jiangnan region regards it as an auspicious tree. 1.2 Changes in modern concepts With the development of botany research, more and more families have begun to view osmanthus planting from a scientific perspective. The 2019 home gardening survey report shows that 38% of courtyards in the Yangtze River Delta region have planted osmanthus, and it is increasing year by year. 2. Four major precautions for indoor planting 2.1 Air circulation management Adult osmanthus trees consume about 0.8 cubic meters of oxygen per hour at night. It is recommended to place them in the bedroom for no more than 2 hours. The timed basin transfer method can be used: place it on the southbound sill during the day and move it to the balcony at night, which can not only ensure photosynthesis, but also avoid competition with people for oxygen. 2.2 Control the concentration of floral fragrance. The concentration of volatiles in a single sweet-scented osmanthus plant in full flowering period can reach 1200μg/m³.
