Proper Brassia orchid care consists of providing temperature, humidity, light, water, and nutrients that are at least similar to their natural environment. Growing spectacular Brassia orchids can be accomplished by optimizing these key factors. To determine these factors we use what we know about where they live naturally.The genus of Brassia can be found naturally in Central and South America and the West Indies. Some can also be found in South Florida. They grow naturally mainly in wet forests at elevations that range from sea level up to 3000 feet above sea level. The Brassia orchid is an epiphytic plant and grows in trees and anchors itself to the bark. The temperature where they are found naturally averages 55 to 60 degrees Fahrenheit during the night and 65 to 70 degrees during the daytime. From this information we can determine what the plant needs in respect to five factors above.
Temperature
With the average temperatures listed above it can be determined that an optimal temperature during the growing season will be between 75 and 80 degrees Fahrenheit. During the resting season or cool season the optimal lowest temperature will be around 65 degrees Fahrenheit.
Humidity
Because Brassia are found in wet forests and at low elevations, you can safely say that they prefer humid conditions. Lower elevations are normally more humid than higher elevations. To survive during drier times, epiphytic plants absorb moisture from the air and this makes humidity a necessity. Most epiphytic plants require at least 50% humidity during growing season with an optimal humidity of about 70%. A humidity tray may be needed if your are attempting to grow Brassia in your home.
