Cymbidium orchids are tropical flowers with thick, hard, waxy blossom petals. Long flower spikes grow with 20 to 30 blossoms draping from the stalk. These blossoms are 1 to 5 inches across. The annual blooms are available in all colors but blue and red. Leathery green leaves reach 1 to 2 feet tall and spread 1 to 2 feet wide. Cymbidium orchids enjoy cool moist growing conditions. The most popular use for this orchid is for corsages. Cymbidium orchids need repotting every two to three years during the spring before new growth begins.
Wash the plant pot with soapy water and rinse it with one part bleach and nine parts water. This sterilizes the new container by eliminating hiding pests and diseases. Drill drainage holes in the bottom of the container if there are no holes.
Mix together six parts redwood bark chips, one part coarse charcoal and one part peat moss in a large bucket. This produces a good-draining mixture with organic materials. Place 2 inches of your potting mix in the bottom of the container.
Remove the cymbidium orchid from its container. Be gentle so you do not damage the roots. Place the orchid in its new plant pot and fill it the rest of the way with your potting mixture. Gently firm the mixture around the orchid.
Fill a 3- to 4-inch deep tray with pebbles. Pour in enough water to fill the pan to just below the top of the pebbles. Place your repotted cymbidium orchid on top of the pebbles. This will increase the humidity around the orchid.
Place your cymbidium orchid in a location with bright indirect light. Refill the pebble tray anytime that the water level drops to halfway below the pebble layer.
