The delicate beauty of orchids has given them a reputation as being difficult to grow. Not so, said Billy Edwards, who's grown orchids for five years. The most important thing to remember, he said, is don't overwater.
There are many species of orchids, but the most common variety found in stores and florists around Chattanooga is phalaenopsis. Some bloom twice yearly, larger ones just once, he said.
Here are Mr. Edwards' tips on caring for them.
1. Growing media: A fresh, fast-draining, but water-retentive medium is imperative for a healthy root system. Some of the most popular are bark-based mixes and those with a peat-moss base.
2. Water and fertilizer: Allow to dry between waterings. Pick the container up, and you can feel it when it's dry. Put up under sink, and let water run into it for a minute or two. Drench thoroughly. Fertilize every time you water with a 20-20-20 fertilizer using 1/4 teaspoon per gallon of water.
3. Light: Orchids need bright, indirect sunlight and are best grown in a window facing east, west or south. If using fluorescent lights, place cool and warm fluorescents roughly 12 inches from the plant.
4. Temperature and humidity: Temperature should be 70 F to 85 F. Bathrooms with enough light are excellent growing locations due to their humidity levels. Or set the orchid container in a shallow tray filled with pea gravel and water.
5. Insect and disease control: Basic insecticide soap sprayed onto the orchid once a month -- or more when infestation is present -- will help prevent damage from mealy bugs, scale, white flies, moth flies and other critters that eat on the roots and blooms of orchids.
