How to Bloom Cymbidium Orchids
- 1). Plant the cymbidiums in a potting medium of a medium-grade fir bark, peat moss and perlite. The pot should be large enough to avoid crowding. Position the active growing bulbs furthest from the sides of the pot. Hold the plant in the pot as you add the potting medium, working the medium around the roots carefully.
- 2). Place cymbidium orchids near a bright (but not hot) window. Northern exposure probably won't supply sufficient light, so choose the brightest of eastern, western and southern exposure.
- 3). Keep the plants away from heating vents. While cymbidiums require a lot of light, they also need cool temperatures.
- 4). Place the pot on an evaporation tray and keep water in it at all times. Humidity should be between 40 to 60 percent.
- 5). Mist the plant a little each day with a spray bottle (preferably filled with filtered water). Cymbidiums require constant moisture.
- 6). Feed the orchids every time you water them. Feed them with a water soluble 20-14-13 orchid food for three consecutive feedings then feed with a water soluble 11-35-15 every fourth feeding. During the spring and summer, water heavily, keeping the potting medium continually damp; during fall and winter, keep potting medium barely moist.
- 7). Repot the plants every two years because the potting medium decomposes over time. Repot in the spring after the plant's blooming period has ended. You can divide the root bulbs into separate plants, if desired, but divisions must have at least three bulbs to produce blooms.
