The Rhizosphere: How Indoor Plants Really Clean the Air | Gardening Australia

Ever wondered why being around plants makes you feel better? It's not just in your head — science says so. In this video, two leading researchers take us into the glasshouse to explain the rhizosphere: the compact, root-level ecosystem where plants and bacteria join forces to strip harmful pollutants from the air. We explore everything from carcinogenic petrol vapours in underground car parks to easy changes you can make at home to help your indoor plants do their best air-cleaning work.
