Houseplant Appreciation Day is celebrated on January 10, 2021. A houseplant is a plant that is grown indoors in places such as residences and offices. Houseplants are commonly grown for decorative purposes, positive psychological effects, or health reasons such as indoor air purification. Plants used in this fashion are most commonly, though not always, tropical or semi-tropical.
Major factors that should be considered when caring for houseplants are moisture, light, soil mixture, temperature, humidity, fertilizers, potting, and pest control. The following includes some general guidelines for houseplant care. For specific houseplant needs, the tags that sometimes come with plants are notoriously unhelpful and generic. Specific care information may be found widely online and in books.
Indoor plants reduce components of indoor air pollution, particularly volatile organic compounds such as benzene, toluene, and xylene. The compounds are removed primarily by soil microorganisms. Plants can also remove CO2, which is correlated with lower work performance, from indoor areas. The effect has been investigated by NASA for use in spacecraft. (With material from: Wikipedia)
