| has shown that the popular spider plant consumes tobacco smoke and that philodendrons and aloe vera are effective air purifiers. To help your plant collection improve the quality of indoor air, place a layer of activated carbon at the bottom of each pot before adding soil; place a drop or two of grapefruit seed extract or tea tree oil or a tablespoon of topical hydrogen peroxide in drainage dishes every week before watering to prevent the growth of mold and bacteria in standing water; keep air circulating around the plants with a low speed fan; position plants at different heights; use a variety of plants; position shade-loving plants in areas that receive little or no natural light and place sun-loving plants near windows; use at least one plant for every 100 square feet of floor space (two is better) in rooms of average height and increase the number of plants for rooms with high ceilings, in areas in which cigarettes are smoked or in homes near busy highways.

For a wealth of information on indoor gardening, see your local library and visit nurseries and plant stores. |
