Dendrobium Orchid (Dendrobium sp.)
Orchids from the jungle absorb carbon dioxide and release oxygen at night, the opposite of most plants. Dendrobiums are moderately effective at removing alcohols, acetone, formaldehyde and chloroform from the atmosphere.
Each variety of orchid has specific care requirements, so consult the care instructions to ensure your indoor environment is ideal for promoting the plant to bloom (flowers can last a week or up to several months, depending upon the species).
Mist often and water generously in the spring and summer. In the winter, water just enough to prevent the bulb from shriveling; do not feed, but do continue to mist often.
Overwatering can promote fungal infection, and spider mites and scale insects will descend if the air is too dry.
Plant in commercially prepared orchid mix. These plants are finicky. If no commercial orchid mix is available, use decayed oak leaves, Spanish moss or sphagnum moss.
