how to grow fresh air by Dr B C Wolverton
The EPA state that indoor air pollution is up to 5 times more than outdoor! So do yourselves a favour, get up from your computer right now and throw open your windows!
I guess with double glazing, insulation and wall to wall carpets, along with our desire to fill our homes with new furnishings, MDF furniture and electronic gadgets we are polluting our homes as well as our environment. Add to that the fact that we spend 90% of our time indoors and it’s a sure recipe for ’sick building syndrome’ and multiple chemical sensitivity.
Respiratory infections are a well known consequence of poorly maintained air and air conditioning systems. I bet you can all recount times when one person in an office has succumbed to a cough or cold and within 2 weeks everyone has had it.
Low relative humidity levels are also associated with poor indoor air quality. During the winter months especially, humidity drops well below the ideal range. Cold winter air is normally dry and when you add your heating system into the mix you’ve got the perfect conditions for colds, allergic attacks and asthma.
Well, there’s good news from Dr Wolverton! He did some lengthy studies on houseplants and their ability to purify the air.
So, if you end up with colds every winter or fatigue, headaches and sinus congestion every day, perhaps all you need is a visit to the garden centre rather than some toxic over the counter medication!
You may remember from your biology lessons at school that plants breathe in carbon dioxide and breathe out oxygen during the day. This increases humidity which helps to improve the quality of the air. According to Dr Wolverton, some plants also absorb pollutants from the air such as formaldehyde, toulene and benzene.
Following research, the recommendation is that you use 15 to 18 good-sized houseplants in 6 to 8-inch diameter containers to improve air quality in an average 1,800 square foot house.
The best plants for removing trichloroethylene were Gerbera daisy (Gerbera janesonll), Marginata (Dracaena marginata) and Peace Lily (Spethiphylium “Muana Loa”)
The best for removing benzene were Gerbera daisy (Gerbera janesonll), Pot Mum (chrysanthemum morifollum), and Peace Lily (Spethiphylium “Muana Loa”)
The best plants for removing formaldehyde were Bamboo Palm (chamaedorea selirizll), Janet Craig (Dracaena deremensis “Janet Craig”) and Mother-In-Law’s tongue ( sansevieria laurentii).
Now you have a great excuse to indulge yourself in some of nature’s finest gifts and be sure to give your friends plants whenever they move into a new home. It could be the best gift they receive!

I grew up with houseplants as my mother was very keen on their purifying qualities as well as their beauty. Dragon Plants (Dracaena) and Spider Plants (Chlorophytum comosum) were what I started with but now I have several exotics and my husband is just as into them as I am. When friends come to dinner they all go away with a little cutting and the enthusiasm for houseplants grows. I consider houseplants just one of the ways to ‘Green’ the home, add beauty, and be a little micro-hobby that even the busiest person should have time for.

Hello Mrs Green! I will check that book out. Now that I have no proper garden, just a very small narrow concrete path outside my flat and a wall, I am going to start growing more house plants. A good way of growing house plants for free and recycling is using seeds from fruit. Occasionally I treat myself to an avocado and the big seed germinates pretty quickly and grows into a nice plant. We gave the last few away as gifts, but I will grow another one and show the process in a blog post perhaps.
Speak soon, keep up the great work x

Hi Shauna,
What lovely memories you have of your home full of plants. My first houseplant when I left home was a spider plant, but my cat LOVED the thing and ended up eating it! It’s beautiful that you send your friends away with cuttings. I love that idea.
Anna-Lisa, it is so good to see you again. I think of you often. Oh do grow another avocado and lots of houseplants too! the book is well worth a read; I got mine from the library and was so inspired by it. I’m not good at looking after plants for some reason, but this motivated me to get into it more.
