Full description and specifications
From the point of view of cultivation, for Calanthe Rubra, the culture mode typical for the Cattleya genus can be applied, with strong to moderate light (25000 - 35000 lux), strong permanent ventilation and temperatures of 18℃ at night and up to 26℃ during the day , to benefit from a vigorous growth regime. The recommended humidity for this taxon will be between 40% and 80%, depending on the growing season.
Being a taxon with seasonal growth, similar to the genera Cycnoches and Catasetum, it is recommended to make the growth process more efficient in the appropriate period, in order to obtain pseudobulbs of the largest size during the summer, by frequent administration of water and fertilizers. After the ripening of the pseudobulbs, the watering will be gradually reduced, until the leaves fall, at which point the water administration will be completely stopped.
The substrate used must have the ability to retain moisture, but at the same time to quickly and efficiently drain the excess water, we recommend mixes specific to groups of orchids with terrestrial growth. They can contain fir or pine bark, sphagnum moss, peat, but also organic matter or horticultural soil. Calanthe Rubra also lends itself well to hydroponic culture.
Fertilization will be administered twice a week during the growth period, and will be stopped during the rest season, after the leaves fall.
In exceptional climatic conditions, when humidity and temperature remain constant, one can notice a continuation of growth without a rest season, and sometimes without flowering, its initiation being closely linked to the presence of a dry season, as in the case of the Catasetines. In this case, if the initiation of leaf fall does not occur by itself, it is recommended to intervene by reducing and stopping the administration of water, a practice also applicable to species of the Dendrobium genus in monsoon climates.
Flower size approx. 5-7 cmGenre/Type: Specialties
