Cattleya Orchids Growing Tips

Cattleya orchids are one of the most common species grown and are often referred to as corsage orchids thanks to their big flowers. The flowers can measure up to eight inches and are also fragrant. If you want to grow one of your own, there are a few things you should know beforehand.

Humidity

Maintaining proper humidity levels is extremely important when caring for one of these plants. The relative humidity in your home should fall between 50 and 80 percent. This can easily be done by using a humidity tray. Simply sit the orchid atop a tray of gravel filled with a little water.

Air Circulation

It is more important to provide adequate air circulation in a high humidity environment. This helps prevent the plant from falling victim to a bacterial or fungal disease. Cooler temperatures can also increase the risk of one of these diseases when there isn't proper air circulation.

Temperature

It's best to have a higher temperature level during daytime and a lower level at night. During the day keep the temperature between 70 and 90 degrees Fahrenheit and at night, it should be between 50 and 60. The maximum temperature you can expose the plant to, without causing damage is 95 degrees Fahrenheit.

Water

Cattleya orchids are epiphytic, or air plants, which means that they have organs that store water called pseudobulbs. These plants also have large roots covered with velamen which help retain water. Let the plant dry out almost completely between watering, however you will need to provide a bit more water while the orchid is in active growth.

Light

Light is the single-most important factor when growing cattleya orchids. They need at least a half day of bright light but make sure you don't allow direct sun during the middle of the day. The leaves will have a medium-green color if the plant is receiving the correct amount of light.

Fertilizer

Fertilize these plants on a regular basis. If your plant is potted in fir bark, use a fertilizer with an elevated amount of nitrogen. Formulations with more phosphorus or potassium will deliver better flowers and sturdier growths. However, it should be used rarely. When the orchid is resting, you should apply fertilizer once a month. While growing, it's best to give fertilizer every two weeks.
