The fact that plants have a positive effect on their immediate environment and our wellbeing is one that has been proved by scientific research, but not everyone knows the exact amount of plants they need per room in order to maximise those effects. Considering Australians are now spending around 90 per cent of our time indoors, ensuring our working and living environment has a positive impact on our health is now more important than ever.

Horticultural initiative Plant Life Balance joined forces with the scientists at RMIT University in Melbourne to analyse past and present research on the benefits of plants, and how that information applies to our modern living conditions.

Β The magic number for optimum purification and wellbeing benefits was 10 plants in an average four by five metre room.

While one plant makes very little difference to your wellbeing, a range of plants in different sizes and varietals are capable of making you feel more relaxed, inspired and positive.
