Cymbidium orchids are evergreen perennials native to tropical regions of Australia and Asia. Due to their natural habitat, Cymbidium orchids are best grown indoors as houseplants, though they can easily be kept outdoors during warmer months. The plants are valued for their large, colorful flowers that bloom during any season--including winter. Cymbidium orchids are relatively easy to care for and add an exotic burst of color to any room.
Keep Cymbidium orchids in a location that receives bright morning and afternoon sun with partial midday shade. Maintain a constant temperature of 70 to 80 degrees Fahrenheit during the day and 50 to 65 degrees Fahrenheit at night.
Water Cymbidium orchid plants once every 7 to 10 days, allowing the soil to dry out slightly between applications. Water during the early morning to allow excess moisture to evaporate before temperatures decrease in the evening.
Mist Cymbidium orchids once per day using a spray bottle filled with warm water to increase the relative humidity of the air around the plants. Alternatively, place a humidifier near your orchids to raise the humidity and negate the need for daily misting.
Feed your Cymbidium orchid plant once per month using a high-nitrogen 25-9-9 NPK fertilizer from February to July and a 6-25-25 NPK fertilizer from August to January. Apply by combining 1 tsp. of fertilizer with 1 gallon of water and pouring over the soil.
Repot Cymbidium orchids once every three years between the months of February and June. Plant in an orchid soil mix to provide the proper fertility and drainage for the plant. Increase the size of the pot by about 3 inches at each repotting to allow plenty of room for growth.
