Green plants that release oxygen at night, the green guardians of home air
Snake plant (Sansevieria) can remove harmful gases such as toluene, formaldehyde, hydrogen sulfide and trichloroethylene from the air. It can absorb carbon dioxide at night and produce oxygen. One medium-sized snake plant can absorb more than 80% of various harmful gases in a 10 sq m room, and 2 snake plants can basically completely purify the indoor air.
Because it can produce more negative ions, it can improve the reduction of negative ions caused by turning on TVs and computers in a room, and it is quite effective at improving the indoor environment. Snake plant is also one of the most popular plants in South Korea and Japan.
The snake plant's long, narrow leaves are mottled like tiger stripes, which is how it got its name. This type of plant is very peculiar; sometimes it has no stem at all, and can grow small pale green flowers from the ground. As long as there is soil, it shows excellent vitality, so it is also called "thousand-year orchid" and is a favorite indoor plant among office workers.
The snake plant's color is relatively understated and elegant, and its leaf shape resembles a sword, strong and upright. Shorter snake plants can accent a study desk or windowsill. Because it releases oxygen at night, it is also often placed in the bedroom to accent a bedside table.
The snake plant can be called a bedroom plant; even at night it can absorb carbon dioxide and release oxygen. Six waist-high snake plants can meet one person's oxygen intake. Growing snake plants indoors together with coconut coir charcoal can not only improve people's work efficiency, but also reduce the need to open windows for ventilation in summer.
The snake plant has vigorous growth. It is not strict about light, but grows best in a semi-sunny, ventilated spot. It needs no careful care and is rarely troubled by pests and diseases, making it the first choice plant for office workers. Whether or not light is sufficient, it can adapt well to the environment. Normally water when the soil is dry; even watering once after a long time is fine. The temperature should not be lower than -10°C. Its most suitable growing temperature is 20-30°C. It is not demanding about potting soil, and fertile leaf-mold loam is best. If it has been planted a long time and is too crowded, it should be divided, which can be done together with repotting.
