Spider Plants are air purifiers. They are hardy and thrive with minimal maintenance. Moist soil is recommended but an occasional drying out won’t hurt them. Bright and indirect sunlight is preferred, ut it can tolerate moderate lighting as long as it is not directly exposed to the sun. The plant must be fertilized every two weeks. Spider plants clean the air of carbon monoxide, formaldehyde, benzene and xylene. They are safe for children and dogs, but they have a very mild hallucinogenic effect for cats.
