The most common mistake beginning orchid growers make when choosing their first orchid is to purchase the showiest plant.
Unfortunately, the showiest orchids are often the most difficult to grow. Four of the most popular orchids are Cattleyas, Phalaenopsis,
Paphiopedilums and Oncidiums. These orchids are not only beautiful, but they are among the easiest to grow.
Cattleya
Cattleya (CAT-lee-uh), or Corsage Orchid, is the most commonly grown orchid in the home. These epiphytic plants originate from Mexico to Brazil, where they are often found growing on trees. They come in a widearray of colors ranging from lavender to white, red, yellow, orange, green and blue. Cattleyas, or “catts,†as they are sometimes called, are often fragrant. Catts require bright light and some sun to flower. An east or west window is ideal, or a slightly shaded south window can be used.
Artificial lights may also be used. Four 40-watt fluorescent bulbs and two incandescent 40-watt bulbs placed 8 inches above the plants will provide sufficient light. Dark green, limp foliage or poor flowering indicates insufficient light. Catts require a 15 to 20 degree difference in night and day temperature. Day temperatures ranging from 70- 85F with night temperatures ranging from 55-66F are recommended.
Cattleya orchids possess a psuedobulb that stores water, so they must be allowed to dry between waterings. They need 50 to 60 percent humidity in the home. Place the plants on trays of moistened gravel or use a humidifier to increase the humidity. Catts should be fertilized weekly with a onequarter to one-half diluted 10-10-10 or 12- 12-12 fertilizer. Repot Cattleyas every two to three years in the spring. Select a container that is slightly larger than the root system so the plant can grow without repotting for another two to three years.
Good aeration and drainage are essential to successfully growing Cattleyas.
