Follow these simple cymbidium orchid care instructions to keep your cymbidium babies happy, healthy and blooming!
Cymbidium orchids are prized for their long-lasting sprays of flowers, used especially as cut flowers or for corsages in the spring.
Light is important for growing cymbidiums. They need high light but cool temperatures. Leaves should be a medium to golden green in color, not dark green.
Temperatures are another critical factor in flowering cymbidiums. Cymbidiums requre day temperatures of 75 to 85 F (or more) and night temperatures between 50 to 60 F. (Day and nighttime temperatures can be 5 degrees lower during the winter.)
Water to provide a constant supply of moisture to cymbidiums. Water heavily during the growth season (spring and summer), keeping the potting material evenly moist. Reduce water when the pseudobulbs complete growing in late summer. (The pseudobulb is a storage organ derived from the part of a stem between two leaf nodes.)
Humidity should be kept at 40 to 60 percent. Keep air circulating to prevent orchid pests and diseases.
Fertilizer should be applied during the growth season (spring through late summer), high nitrogen fertilizer (such as 30-10-10) is used. In late summer, use a high-phosphorus, blossom-booster fertilizer (such as 10- 30-20), to help form bloom spikes.
Potting is usually done in the spring after flowering, usually every two years or when the potting medium decomposes. See pages 55-61 in Orchids Made Easy for clear step by step instructions and illustrations to show you how to repot an orchid.
