    Courtship. Among dendrobiums, two groups of species can be distinguished. The first include immigrants from the Asian continent. They require high temperature, as well as humidity of air and substrate during the period of active growth. During the rest period( winter months), they need relative dryness and low temperatures( 10-13 ° C).The second group consists of species inhabiting the islands of the Malay Archipelago, Australia and New Guinea. In the period of active growth, they need a uniform, high temperature( 28 ° C), 90-100% of air humidity and an abundance of light. The rest period is experienced at a lower temperature - 18-20 ° C - and moderately humid air. The lower the temperature, the more dry the air should be. Dendrobiums must be planted in small pots with a lot of drainage holes, preferably in baskets or special boxes. Completely do not stand the stagnation of water at the roots and require good ventilation in the terrarium! As a substrate, most standard mixtures are suitable. For example: 1) pine bark, sphagnum and dry shredded beech leaves( in the ratio 2: 2: 1);2) the roots of the royal fern( osmunda), pine bark, sphagnum, dry beech leaves( 3: 2: 2: 1);3) the roots of the fern of the centipede( polypodium), sphagnum, and the leaves that have perished( 2: 2: 2).Other combinations are also recommended.
