Houseplants, Air Quality, and You

IrisesIt’s houseplant appreciation day! I did not know this, until fellow blogger This Veggie Life mentioned it (https://thisveggielife.blog/2018/01/10/houseplant-appreciation-day/). Evidently I am not the only one who loves to have plants around!

So take a moment to water your plants. Repot them if they are getting a little root bound – or buy yourself a new plant for your desk or your home. Here’s my confession – I am more of a light green thumb than a true green thumb. But, I’m working on it. My goal this year is to keep more plants alive than I let go through neglect or any of the many errors we all make with watering, light, and so on. Actually, I’d love to be able to pull of a jungalow style! (look it up on Pinterest – it’s a thing!)

I don’t know about you, but when I walk into a space full of lush green plants, I just feel like a breathe easier. Science says that we actually do breathe more easily when we have plants indoors.

A team of researchers in Portugal wanted to find out if this effect works for schools as well. After nine weeks of looking at the air quality of school rooms with six hanging potted plants compared to rooms without plants, as well as outdoor air. The rooms that contained plants had a higher indoor air quality – lower levels of volatile organic compounds (VOCs), lower levels of carbon dioxide, and even lower levels of particulate matter in the air! The research appeared in the Journal of Toxicology and Environmental Health in 2012 (https://www.ncbi.nlm.nih.gov/pubmed/23095155).

NASA has established that there are certain plants that do the best job of improving indoor air quality. Researchers there started looking at the question because if humans are going to live in space, we are probably going to be living in enclosed areas. The NASA teams wanted to know which plants would be most useful in that kind of environment. The answer is a list of plants that you can find easily, including golden pothos, English ivy, Peace lily, potted mums, and gerbera daisies. You can find the study results here:  https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930073077.pdf On the whole, the plants improved the air in numerous ways, including removing benzene and formaldehyde from the air.

People are happier and more creative when they have plants in their workspace. I imagine this is true for children, too, although no study has been done to find out. One of the big challenges of course – as any indoor gardener knows – is keeping the plants alive and healthy looking. So, that is a little extra “work” but the pay off in terms of improved air quality and improved mood could be worth it!

Alright, so, I have a personal commitment to buy at least one new houseplant every other month. (On the in between months, I am focusing on lighting!) And I have to say that one of the sites that I am finding most inspiring this year about plants is http://www.succulentsandsunshine.com
