Cymbidium orchids offer beauty and ease of care. The orchid belongs to the orchidaceae family and there are 52 species of cymbidiums. Many hybrids also exist. Cymbidium orchids produce large, colorful sprays of flowers. Widely used in the florist trade for corsages, the orchids can also be cut for bouquets. Miniature cymbidium hybrid varieties can withstand temperatures that top 95 degrees F, unlike the larger cymbidiums. In tropical regions, the cymbidium flourishes outside year round.
Place the cymbidium where it receives morning sunlight but afternoon shade. The orchid prefers a ratio that consists of 55 percent shade. If the leaves begin to turn yellow-green, then the plant is receiving too much light. Too much shade will reduce the orchid's flowering ability.
Maintain a daytime temperature of 75 to 85 degrees F during the day. At night, drop the temperature to 50 to 60 degrees F so the flower buds begin to form. During the winter months the cymbidium prefers a cool temperature of 45 to 55 degrees F with a daytime temperature of 65 to 75 degrees F.
Water the orchid heavily during the spring and summer. The orchid should never dry out. During the fall and winter months, the amount of water can be reduced but the medium should still stay moist to the touch.
Mist the orchid daily to raise the humidity level. Place the orchid's pot in a saucer filled with moist pebbles to raise the humidity level. The cymbidium enjoys a humidity level between 40 to 60 percent. During the dry winter months the orchid benefits from a room humidifier.
Place a fan on low in the room with the orchid. The fan helps prevent the development of the Botrytis fungus, which often damages flowers and buds.
Fertilize the cymbidium orchid in the spring and summer using a water soluble 30-10-10 fertilizer. Apply weekly. In late summer switch to a water soluble 10-30-20 fertilizer. Apply weekly until winter and then fertilize once per month.
Repot and divide the cymbidium orchid every two years. Use a pot that is one to two sizes larger then the current pot. Use a medium with fir bark, peat moss and perlite.
