Light:
Tolumnia calochila needs a light level of 20000-3000 lux. These plants require bright, slightly filtered or scattered light and protection from the direct action of the midday sun. Strong air movement should be ensured all the time.
Temperature:
The average temperature of the summer day is 30-31 ° C, night 22 ° C, and the daily difference is 8-9 ° C. The average temperature of the winter day is 28-29 ° C, the night 18-19 ° C, and the daily difference is 10-11 ° C.
Humidity:
The Beautiful Lip Tolumnia needs the average humidity for almost the entire year of almost 85%, and it drops to 80% in winter and at the beginning of spring.
Substrate, growing media and repotting:
Tolumnia calochila are usually grown on rootstocks made of cork, tree ferns or on hardwood branches. If they are mounted, it is necessary to protect high humidity and fogging in the summer at least once a day. Spraying several times may be necessary during extremely hot and dry weather.
Watering:
This species should be abundantly watered during active growth from spring to autumn, but their roots must dry quickly after watering. When new growths reach maturity in late autumn, the amount of water should be gradually reduced.
Fertilizer:
Weekly application of 1/4-1/2 of the recommended dose of orchid fertilizer during active growth is recommended. From spring to mid-summer, high-nitrogen fertilizer should be used, and then until the end of autumn high-phosphoric fertilizer.
Rest period:
The amount of water in winter should be reduced, but Tolumnia calochila can not be completely dry for too long. Fertilization should be reduced or eliminated until spring, when new growths appear and more watering begins. The plants should also provide a higher level of light during this period.
