This month we've chosen the genus Echinacea.See More
This handsome, glossy-leaved orchid hails from low to mid elevation regions of South America. Of the 15 species of Zygopetalum, many are terrestrial. With multiple blooms that often in flower for 8 weeks, theymake excellent cut flowers and are used commercially for this purpose. The pseudobulbs are eventually deciduous. This orchid's generic name is derived from the Greek term for "'yoked petal,"' referring to the yoke-like growth at the base of the flower lip.
Temperature: Zygopetalum Orchids will tolerate considerable summer heat as long as they have mild night time temperatures between 50-65 degrees Fahrenheit. Exposure to cold temperatures (down to 28 degrees Fahrenheit) for a few hours each night will not damage an acclimatised plant but once the plant spikes or flowers, it should be protected from temperatures below 35 degrees Fahrenheit. Always keep these plants free from frost.
Light: Your Zygopetalum enjoys the morning and afternoon sun but should be protected from hot midday sunlight. A light green leaf with just a hint of yellow indicates that the plant is receiving the maximum amount of sun it can take; a dark green leaf indicates that it needs more sunlight.
Water: Watering of Zygopetalum is a delicate balancing act. They should not be allowed to 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.
Feeding: High nitrogen fertilisers (25-9-9) should be used from February until July, while low nitrogen fertilisers (6-25-25) should be used from August until January. Feed one teaspoon to a gallon of water once a month.
Repotting: Repot 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.
