Cymbidium Orchids are admired and enjoyed throughout the world. They are a hearty species of orchid, and endure an extreme variation of temperature for short periods of time. They produce flowers of stunning beauty and surprising color variation. Whether you are a fan of cleansing white petals with pink centers, or a rich, almost velveteen red or purple hue, these exotic flowers can brighten any home or garden.
According to the Cymbidium Society of America, Cymbidiums grow in the mountains of East Asia, the coasts of the Mediterranean Sea, the northern spaces of Australia, South Africa and the California coast. These orchids enjoy warm days and cool nights, preferring temperatures that range ideally from 75 to 50 degrees Fahrenheit. They can endure extreme temperatures of below 30 degrees Fahrenheit, or above 95 degrees Fahrenheit. So long as these flowers have access to water, they will endure harsh conditions for reasonable lengths of time.
The CSA suggests that these orchids receive regular exposure to filtered sunlight. If the plant is becoming darker and richer in its shade of green, the plant is not enjoying enough sunlight. Healthy plants will have leaves and stems that are a light, yellow-green color.
Cymbidium’s are easy to care for. They require water two to three times a week, and four to five times a week during hot summer days. According to Orchids.com, the best rule of thumb for watering these orchids is simply "More heat, more water. Less heat, less water." The humidity should be kept at 40 to 50 percent.
Cymbidiums can be grown commercially year round, but they naturally bloom in late winter and early spring. The blooms have an impressive life span, and will often retain their beauty for two to three months before they begin wilting. Their colors range from white to bright pastels of orange sherbet, to vibrant purple and richly dark reds and blues.
The CSA recognizes that larger plants produce more flowers. However, they still recommend replacing the potting soil or dividing larger plants to avoid the plant becoming too large to handle. They prefer a moist, rich and slightly acidic soil. Trim back roots, and according to Orchids.com, the plant should be repotted directly after flowering. Be sure the soil drains well.
Cymbidiums are not prone to any particular insects or molds. Spider mites might be found on leaves, and slugs may try to eat flower buds, but there are no insects, molds or other nuisances that particularly plague this plant. Orchids.com suggests an "encapsulated pyrethrum time-release insecticide."
