Cymbidium orchids are favorites because they are long-lasting. They grow well in pots, they tend to produce more leaves than other varieties of orchid and their thick blooms can last for months. Many people grow these flowers to use for cuttings. When cut, the flowers can last up to four weeks in a refrigerator. The key to successfully growing Cymbidium orchids begins with the potting.
Choose a pot that is twice the size of the container that the orchid is housed in when purchased or obtained. Make sure the pot has a drainage hole in the bottom and something to sit on to collect the water as it runs out of the pot.
Place a 1- to 2-inch layer of pea gravel into the bottom of the pot. The pea gravel will make it easier for water to drain. Fill the rest of the pot with potting soil.
Dig a hole that is roughly the same depth as the orchid's growing container.
Remove the plant from its container and place it in the hole. Back fill the hole with soil, leaving the top two-thirds of the plant's bulb exposed above soil level. Gently tamp around the plant with your hands to ensure no air pockets remain around the roots.
Water your orchid lightly. The goal is to keep the soil moist, but not wet or too dry. Plan to water your plant every week to 10 days.
Place your potted Cymbidium orchid in an area where it will receive indirect sunlight. If your orchid's leaves turn dark green, it needs more light. If its leaves turn yellow, it is not getting enough sunlight. A Cymbidium orchid that is receiving the proper amount of light will develop apple-green leaves.
Fertilize your orchid with a 25-9-9 fertilizer each month from February through July. Fertilize with a 6-25-25 fertilizer every month from August through January. Follow dosing instructions of the product you are using.
