Cymbidium will tolerate considerable summer heat as long as they get cool, mild night temperatures (between 50-65 degrees F.). Cold weather, even down to 28 degrees F. for a few hours each night, will not damage an acclimatized plant, but once the plant spikes or flowers, it should be protected from temperatures below 35 degrees F. Regardless, plants should always be kept free of frost.
Your Cymbidium enjoys the morning and afternoon sun most, but yet should be protected from the hot mid-day sun. A light green leaf with just a hint of yellow indicates the maximum amount of sun the plant can take, and a dark green leaf indicates not enough sun. How should you correct this if you are having problems? Obviously, if your plant is getting too much sun, move it out of the sun and water it a little more to try to correct the damage. It may be irreparable, though. When your plant is getting too little sun, it’s time to bring it to a place that will give it more direct sunlight. Do not leave it there during hot mid-day sun, but make sure it gets a little extra help.
Watering of Cymbidium is a delicate balancing act. They should not be allowed to go dry, yet they don’t care for a soggy environment either. Watering once every seven to ten days is about right. As with everything else, special consideration must be given for the drying effects of varying ambient air temperature and humidity. Make sure the soil is not soaked, but make sure it is not dry either.
High nitrogen fertilizers (25-9-9) should be used from February until July, while low nitrogen fertilizers (6-25-25) should be used from August until January. Feed one teaspoon to a gallon of water once a month. If you need help with amounts, which fertilizer to use, or how to go about using it, give us a call and we will be happy to help you out and get you on the road to a well fed plant.
Re-pot every two to three years from February to June with a well-draining medium. Fine bark is suitable in mild summer climates, while a finer medium Orchid Mix works well in warmer summer areas.
