Calanthe rubens needs a light level of 20000-30000 lux. The light should be bright but filtered or dispersed, and the plants should never be exposed to the direct sunlight of the midday sun. Strong air movement should be ensured all the time.
Temperature:
The average temperature of the summer day is 29-30 ° C, the night 23 ° C, and the daily difference is 7 ° C. In spring, at the end of the dry season, the average day temperature is 32-33 ° C, night 21-23 ° C, and the daily difference is 9-11 ° C.

Humidity:
From spring to autumn, The Reddish Calanthe needs the humidity of 80-85%, and at the end of autumn and winter it drops to 70-75%.
Substrate, growing media and repotting:
Calanthe rubens require a fertile, perfectly permeable substrate. You can use a mixture of 1 part of fertile clay soil, 1 part of well-fermented manure, 1/2 part of cut osmunda fern and 1/2 part of chopped tree fern fiber or a mixture consisting of 6 parts of fine bark, 1 part of pearlite or pumice, and 3 parts of peat mixed with live moss sphagnum. One part of charcoal can be added to each of the aforementioned mixtures, which improves the airiness of the substrate and prevents it from getting sour. After reaching maturity, they lose their leaves, and then grows inflorescence. It also recommends reducing or even stopping watering when the plants bloom.
After flowering, the plants should be removed from the pots, pseudobulbs cleaned, and all old roots removed. The plants should be divided into individual pseudobulbs and then for the winter season located without roots in a cool, dry place. When new growths reach a height of about 5 cm in spring, they should be planted again. These plants should be split and repotted each year, because this ensures the creation of flowers.
Watering:
Precipitation in a natural habitat is abundant from mid-spring to autumn. Then their number drops sharply and there is a dry season, lasting from late autumn until the beginning of spring. Calanthe rubens should be abundantly watered during active growth, but excellent drainage and aeration of the substrate must be ensured, which can never be soggy or damp.
Fertilizer:
It is recommended to use 1/2-3/4 of the recommended dose of fertilizer for orchids in the growing season every week. These orchids require high doses of fertilizers. You can use sustainable fertilizer throughout the year, but also can use high-nitrogen fertilizer from spring to mid-summer, and then until the end of autumn, high-phosphoric fertilizer.
Rest period:
In the winter and at the beginning of spring, the amount of water should be significantly reduced or even eliminated during flowering, and then you should stop watering until the spring appears new increments when the Calanthe rubens are repotted. Fertilization should be eliminated until new growths appear and spring watering begins in the spring.
If it's native malaysia and thailand, why this article writes all about how they lived in 4 season rather than 2 season?
ReplyDeleteThere are 2 seasons: dry and wet season in Malaysia and Thailand. 4 seasons mean the more precise date of the year!!!
